47 functions and 59 parameters that are important when choosing a printer and MFP

Printer - an external peripheral device, the main purpose is to display a graphical and textual information on a solid physical media (paper, thermo).

Information stored on a computer or other electronic media, with the ability to connect to the printer in a wired or wireless way to transmit information.

Devices called MFP - combined the functions of the scanner, copier, printer and fax.

Recommendations for choosing a

Buying a vehicle with one function will not solve the problem arising 2-3 - decision MFP - a device with a large number of different functions.

When you select should answer the points stated below:

1. Where the device will be used at home or in the office? Depending on the cases in which the device will be used, it depends on a set of functions. For home use MFP with a smaller set of features for office - with a lot.
2. What are the requirements to the device. In many cases, the IFI and the printer is purchased for specific tasks, taking into account which is held model selection.
3. What speed should be ensured in the implementation of the MFP. This indicator measures how fast you can get a copy or printed material.
4. How many people will work in the office or at home with the purchased device.
5. Do I need access to the Internet. Internet access function is implemented in the remote sending cases to print.

   It should be noted that the connection to the network can significantly increase the functionality of the device.

The printer creates only a graphic print on a sheet of black-and-white and color. Therefore, initially to be the choice of the machine, with emphasis on printing functions.

Ease of use and cost, as well as the availability of service - separate devices are more expensive, as well as their repair. Further, how much space to allocate to the device - desk, bathroom, separate area.

There are different categories for the MFP:

• small working groups,
• the middle group,
• to ensure high performance.

Personal devices with a small number of functions. Machines in this category are suitable for home and small office, where work is carried out in the directions:

• printing,
• scanning,
• installation of facsimile,
• up.

The models are the smallest in size and are not designed for high loads. Characterizes these devices are as follows:

1. Significantly saves space on the desktop.
2. Multitasking, simultaneous execution of multiple types of work.
3. Intuitive panel.

Office model. Used for network printing, built-in web interface and facsimile communication, the ability to integrate with existing document management systems - for home use is required.

Classification of the MFP of this group held the performance, the number of people using the device - the main categories:

• Up to 5 people. Model for small workgroups. Performance in this case is relatively small.
• From 5 to 25 people. For the middle of the working group - the simultaneous execution of multiple tasks.
• More than 25 people - a high performance system, are installed in the offices of a number of staff of over 50 employees.

The special features include:

1. The optimum ratio of a set of specifications and functions set.
2. Ease of use, installation, operation and management. When you create a technology that is included in this group, it takes into account that will be used untrained personnel.
3. Laser technology copying documents formats A6-A3.
4. The possibility of organizing a network to send the original document to print - no purchase of additional stand-alone printers.
5. Control panel push button or touch-type, as well as multi-language menu. Touch Screen Control will greatly enhance the functionality - the control unit is less.
6. Getting multiple copies of a single scan - increased productivity.

For medium-sized workgroups Consider the availability of functions:

• two-sided printing,
• auto sheet feeder with the coup and the stock feeder for 200 sheets - a standard set.

In this case, there are several standard elements:

• For ease of use the screen functionality provides support for context-sensitive help.
• Conventional models only work with sheets of 80g / m². However, in some cases it is necessary to use high-density paper. Therefore, the models provided with a paper work, density up to 216 g / m² - the presence of the bypass tray.
• The presence of unique networking functions: scanning for Email, the ability to send and print documents over the Internet.
• Collection of statistics, accounting for the use of the device.
• Network connectivity to Ethernet (port RJ45), as well as the ability to connect parallel port interface.

In such devices the high cost, but also high efficiency. Often they acquire for small and medium-sized office. However, not all the feature set and performance is sufficient for the task.

For large offices highlighted the following features:

• Sending documents for printing via the Internet.
• Automatic printing on both sides.
• Grouping sheets on a certain basis.
• Automatic and semi-automatic stapler. Mechanism holds a certain amount of bound sheets.
• Using paper weighing 200 g / m2, with the lower trays.
• The high rate of loading, which enables printing of up to 400,000 prints within one month.

Application area

To simplify the choice of MFP model makers spent conditional classification application devices - common groups:

• The small office is represented by one or more rooms for workers, one user is connected to the MFP.
• Personal - for use in the home.
• Large and medium-sized office represented by a large number of users. Users are connected to a single printer or MFP to display digital information on paper.

Personal printers and MFPs, as a rule, it is common and low-end models.

Is used under the condition of a small print volume. Not provided functional expansion through compartments for modules, usually laser and LED printers.

For small office devices are able to print from 10 000 to 50 000 pages per month norms without knots wear. The expensive models with similar performance provides the ability to use plug-ins and are characterized by a huge number of functions.

For the average office model, with a capacity of 50 000-100 000 sheets per month. Set in large offices, to facilitate the work of staff connected to the local network without being tied to a particular desktop. Given the high productivity, the feed and receiving trays, calculated on 1000 sheets or more.

For large office performance index greater than 100 000 pages in daily work for 30 working days.

As a general rule, established interfaces allow simultaneous connection of multiple devices.

Conclusion: The note which category applies to the printer or MFP. Performance - an important feature, but just is not recommended for it to carry out the selection of models.

Manufacturers often make mistakes when you create a product, for example, the high-performance model malovmestitelny tray or a slow connection interface cartridges with low ink level.

Types of printing technologies in the MFP

The functions for which a classification of printers and MFPs is extensive, but the main classification - used technology of drawing ink.

Laser printing

The laser is used to form an image on the photosensitive drum. After the starting material has been loaded or scanned is its transfer to paper. As the ink used toner powder special magnitosoderzhaschy - created from polymer micropellets.

Once the information is transferred to the photosensitive drum is its fixing on the sheet (in non-bound form), then the sheet passes through a heated roller (oven) and fixed on the paper.

Fixed toner is not afraid of water exposure.

LED models are based on a technology similar to the technology of laser toner deposition. This design is based on a static line of LEDs (in models of laser travels along the drum), the magnetizing image on the photosensitive drum. The use of this technology reduces the cost of the device.

Laser technology is less reliable, but less effective, and the LED has a more complicated system. LED technology is quite rare, but still deserves attention.

inkjet printing

The technology involves the use of microscopic ink droplets formed on the print head. The head, is a special matrix with nozzles (nozzle). Through them there is squeezing the ink.

The technique involves two methods of forming droplets:

• piezocrystal is used with a special diaphragm,
• It uses a heating element located in the vicinity of the nozzle head.

When using an electric discharge of the piezoelectric crystal causes bending of the crystal, which causes the impact on the diaphragm. The diaphragm pushes ink out of the nozzle.

The method is widely used by Epson printers to create. The second method is also based on the electricity supply, after which there is heat and extrusion nozzle ink. The development of technology uchuvstvoval Canon and Lexmark company.

Sublimation printing

Sublimation printer based on the use of tape with a dye on the surface. The head, serves as an active element, represented by a set of thermocouples, upon heating which solid ink passes into the gaseous state, in contact with the paper becomes a point on print.

The printing process is divided into 3 phases of R / G / B - the colors red, yellow and blue are applied alternately to form a full color image, the quality is superior to offset and inkjet printing - no rough raster and characteristic of Shred inkjet models.

Small dot size ensures smooth color transition is determined small distance between the head, the tape and paper. Use for printing photographs.

Printing with ink using the methods of solid laser and ink jet coating. When performing work on the transfer of electronic information on the paper is melted solid ink to a liquid state, then transferred to the head and then onto the drum. The drum is in contact with the paper, after cooling the ink remains on the surface of the image.

thermal

Thermal carried out only by using special paper, which reacts to exposure to elevated temperature. The printer contains no ink, toner, and other design elements with the presence of consumables. The virtue of such technology - installing printer practically any angle, as leakage or the precipitation of the active substance (toner, ink) is excluded.

Service is rare. The technology used in the creation of printers intended for mobile use. Example: Device rapid withdrawal of photos on paper - camera instant print using thermal transfer technology.

Conclusion: to perform color printing ink jet printing is preferred (but inkjet printing takes longer), Black and White - Laser.

Continuous Ink Supply System (CISS)

Continuous ink supply - significantly reduces the cost of the output of the digital information on the physical media several times, the system reduces the amount of ink used when printing and costs print.

Printers and MFPs with a similar system easier to maintain. Due to the fact that the ink is supplied to the executive head from the container, refill the syringe is made. Each tank is reserved for cyan, yellow, magenta, black.

Conclusion: The system can significantly save on maintenance of the printer or multifunction device. Suitable for printing large volume.

pigment ink

Special ink dries quickly and well absorbed. Often pigmented inks are ink jet printers. Pigment type inks are based on the dry powder dye, water, and special additives.

Almost all of the options of inkjet MFP and printer models work with inks by water based.

The special features of using the aqueous ink include:

• Realistic transfer of shades that allows you to create vivid and realistic pictures, the display of special effects.
• Ink washed off if the surface of the printed material gets wet. Therefore, you should avoid it.

Adding pigment determines the following:

• Resistant to water.
• Light has no effect on the printed image. Generally, after prolonged exposure to sunlight on the image printed aqueous ink, burnout occurs. Pigment inks are based on the fact that they will not lose their quality with prolonged exposure to light fingerprint.
• Pigment inks are resistant to handling. High humidity and temperature changes do not adversely affect surface quality.
• Using ink for double-sided printing - ink does not penetrate deeply into the structure of the paper.
• Long term storage of printed material, over time, they do not change their brightness, contrast.

Conclusion: The pigment ink well transmit all the features of the created image. In this case, the cost is low because of the water base, which simplifies the process of refilling the cartridges.

color printing

Initially, the printing device were given only black-and-white image. Monochrome printers and MFP gradually recede into the past, they were replaced by models with color printing.

Black-and-white device, although it is still very popular as a cost-effective way to print documents. Black and white printing speed up the process that much important in solving everyday office tasks.

Color printing with the economic side, is much more expensive. This is due to the fact that the colored pigment is more expensive, each color separately dressed, image sources often contain a solid color fill (background) - when printing large consumption of red.

Conclusion: for office use it is advisable to use the equipment for black and white printing. Suitable for home use models with color printing.

device type

When choosing peripherals consider the functionality that allows you to divide the printing devices into two main categories:

MFP - multifunction device with the features:

• fax,
• scanner,
• printer,
• the copier.

Thus the cost is significantly lower than when buying individual devices.

However, the quality of performance of individual devices above, as well as their cost.

In most cases, used in the production of plastic housing, with low cost. Metal is also used to create the body, but the construction cost and weight is significantly increased.

From the brand manufacturer, determines the quality of the build, the cost of the device. As a rule, in all models, regardless of manufacturer's standard set of features, but differ in the technology used in the production. An example of a situation, the manufacturer installs the cartridge identification chips - to lay the resource on which taken into account the amount of toner / ink, even if such a cartridge refill chip block it (applies to models Epson).

Printers cheaper than the MFP, but only if you want to print, not a copy, select the printer. They are compact, in the production of housing, used plastic. Other construction elements are also manufactured using plastic, which reduces the structural weight and cost.

As a rule, the oblong shape of printers. Printers capable of transmitting sheets by 10 centimeters in width to A0 - a professional jet, wide format model.

It is for models with wireless interface or the ability to connect to them mobile devices (smartphones). In this case, no need to install drivers or software. However, in this case the functional considerably limited.

MFPs are used only with a special program and install the drivers. An example of a situation - getting up and preserving digital documents. With the program adjusts the image, select the type of format in which the electronic document is stored.

Printers used in homes and small offices. For small or large office it is advisable to use the MFP.

scanner type

There are several options in the scanner multifunction device:

• flatbed Scanner - glass masking frame on which the original is placed. As an original document performs conventional paper book with additional film frames. In step scanning starting material is completely static, otherwise the image will appear blurred. The flatbed scanner is popular because it works quietly.
• proheavy scanner - a model designed to scan the individual sheets. To scan the sheet with the bulk source code (book, magazine) will not work. This is due to the fact that during operation there is movement of the source code relating to the establishment of a static sensor.

Popular both technologies combined variants used in some models.

Conclusion: The flatbed scanner is versatile - suitable for home use and office use. On the quality of the scan tablet exceed broaching model. Sheetfed scanner is suitable only for offices that require quick scan documents - forms, contracts.

Expendable materials

resource developer

Developer - ferromagnetic powder (composition powder included in the toner for laser printers) is transferred to the drum after its magnetization laser - that carries a dye developer.

In many models, the developer can be replaced. Resource developer measured by the number of prints, without replacing it. The higher the share, the less have to carry out the replacement.

Conclusion: The increase in the share of the developer increases the service life without the need for replacement of magnetic powder. This figure is rarely indicated in the documents that come in the package. the resource index in the range of 320 - 50 000 pages.

drum life

Drum - magnetizing device is used to transfer toner to the paper. Used in LED and laser printers. Like many other elements of printers and MFPs, limited operating time. Measuring this parameter is carried in an amount of pages, but the resource is higher than that of the cartridge or toner.

Drums are often become part of a cartridge installed inside. Therefore, the resource is a resource of the cartridge. When replacing a cartridge change is carried out and the drum.

In complex, professional models, the drum is installed in a separate module, and replaced at any suitable time. Service life of between 10 000 to 5 million pages.

Conclusion: The low-end models are equipped with a built-in drum cartridges. Expensive models have a separate drum.

Source cartridge / toner

Color toners, ink or toner are used to print full-color images. Cartridge Construction for laser printers and MFP - generally elongated vessel, the inner chamber is a screw, stir the developer with dye. The resource color cartridge range from 350 up to 540 000 pages.

Suitable for home use model, which is enough for the toner 1 000-5 000 pages.

Cartridges for ink-jet models, the stock to print less. Typically, the ink lasts for 100-300 pages, and the cost of the cartridges themselves great.

The resource color cartridge depends on:

• Production technology and cartridge size.
• features of operation
• compliance with operating rules.

In black-and-white toner higher service life than the color, but the service life of the component b / w cartridge significantly lower resource drum - as a rule, before the change of the drum in the printer 4-5 are replaced cartridges.

At the low-end models resource of 1000 - 5000 pages at high 10 000 -30 000 pages.

It is recommended to use the printer just before the time indicated a small amount of ink. If you use cartridges to complete desiccation, there is a risk of drying nozzle print head, resulting in the impossibility of further work - will require flushing of the entire system.

Violation of the rules of operation and errors while filling the cartridge will lead to significant problems, reduced service life of the cartridge.

Conclusion: Source in an amount of sheets in the inkjet ink of the models calculated flow rate (drops) in laser toner models centimeter inch at 100% fill. Printing full color fills (backgrounds) reduce resource usage and economical mode increases, but the quality of the result is decreased.

Black and white printing is carried out more frequently. Therefore, you should conduct thorough selection of high-performance models.

functions

copy function

The MFP is integrated copy function for control is not required for the computer connection.

An example of using the function:

• The source code is located on the crop frame.
• The top cover is closed - source fixes tightly pressed to the glass of the trimming frame.
• Copy mode is selected: the number of copies, scaling, two-way output (After copying one side is required to shift the sheets back side, then output start copies).

The special features of copying features include:

• The choice of color output - in color or black and white copies.
• The number of copies produced.
• Scaling of the displayed image / text - to be scanned in A4 (source code) to set the output format A5 (copies).
• At the time of copying and display a large number of copies of the unit heats up. Therefore, usually after 20-50 copies (depending on model) is required to stop the printing process (related to laser models). If you do not follow the materials from the print will come out faded (when printing black / white material), with the wrong color (when outputting color copies)
• The thickness of the area to be scanned depends on the original document should be used to sheets or books, other bulk source. Basically presser cover is equipped with a removable "cushion" - when scanning books, magazines cushion is removed.

Conclusion: The copy function is suitable for use in small and large office.

scan function

The scan function is similar to copying, but in this case the material scanned is stored in electronic form. MFPs with copy function can create a copy in electronic form, as a rule, the scanner will give high quality images.

Speed ​​scanner to make copies slower, but better and mostly for storing files used two JPG or PNG format. Each image format specific features:

• PNG compressed image format is saved without loss of quality. The main purpose of the network schedule.
• JPG compressed image format, depending on the compression quality is maintained or reduced.

But with the help of software (included on the CD, such as: ABBYY FineReader) may hold text recognition and image:

• scanned document
• the program recognizes the characters in the image,
• of the image is transferred in text format and is saved for further editing.

In some situations, for example when the paper was badly dented, chances are that the creases lead to a deterioration in the scan result.

Conclusion: If a large amount is provided with periodic multiplication of copies, purchase MFP Scan function - in certain models feature is available without connecting to a computer using a single block memory.

feature phone

phone function is present in the MFP models with the presence of the fax. Dialing is done with the MFP's control panel or by using the software installed on the computer. In the event of failure of one of the components (printer, scanner) to take advantage of the phone will not succeed.

answering machine
MFP models with the phone function, as a rule, are equipped with an answering machine. It serves to answer if the call was not coming call automatically recorded earlier or Answer mode is set to run continuously.

AND HE
There are several standards for determining the number, among which the most common - Caller ID. This standard is supported by almost all the network fixed telephones on the territory of CIS countries. At the time of an incoming call Caller ID system performs request the caller's number from the PBX, and then displays the information on the display.

Caller ID - the standard method for determining the subscriber number, provided that the phone is connected to a digital PBX. During a call or receive a fax on a multifunction monitor displays the sender's number.

Such a feature greatly simplifies the use of the equipment, since it determines the sender by a unique ID number - in this case, reflected seven-digit number, the PBX does not require a connection in the case of Caller ID, the display can be displayed ten-digit numbers.

Conclusion: Due to the high accuracy of the feature recognition subscriber Caller ID number has become very popular, an increasing number of models have begun to support this feature. Before buying check on telephone system works whether this function on your site communication, in the absence of technical capabilities feature useless.

speakerphone - "hands-free" mode. The ability to communicate using the MFP without picking up the handset. The sound output from the external speaker, and capture via a built-in microphone. The speakerphone is used in offices for meetings and conferences.

A tube. There are wired and wireless options.

Typically, the wire tube is characterized by:

• The light weight, since only a plastic housing mounted speaker and microphone.
• Large dimensions.
• The cable connecting the handset and the base unit, with the possibility of rapid replacement.

Cordless handset, Comes with a special "glass" is used for charging. Charger base located anywhere, the range of the wireless connection steps within a radius of 100 meters.

The only drawback - the need to be recharged, for which the tube is installed in the base.

DECT standard. Connection is carried out by the cordless handset DECT standard - used for radio frequencies 1880-1900 MHz for transmission of digital information. DECT standard provides the best degree of protection against listening signal, allows a connection of one tube to several databases - a stream protected 64-bit encryption.

There is also a possibility of creating internal communication between multiple handsets.

Conclusion: if the envisaged use of the MFP in the small or large office, the DECT handset - the most correct choice. This is due to the fact that the signal transmission is carried out without any loss of quality, and to conduct wiretapping impossible because of the high security signal.

fax feature

Facsimile - a method of transmitting images and text information on the analog phone line. To transfer data, usually provided sheetfed scanner and the communication module - information is sent, depending on the model in two ways:

• The scanned document is saved in the MFP memory and sent to a single file. If the facsimile message takes multifunction device, the document is saved in memory - the amount of stored information is calculated in the sheets. fax memory stores from 19 to 5 000 pages. However, many models allow you to set automatic or manual storage of information in memory.
• The document is scanned and sent in real time - in this case, the time required to send and receive, depends on the quality of a communication channel and processing of information by the fax - the maximum data rate of 34 Kbit / s.

The fax feature allows you to track the sending and receiving of documents - a report is generated after the transmit / receive data. For companies it is important, as it confirms receipt of the documents - the parish fax, the address of the sender.

Color fax. Initially, facsimile transmission is used for black-and-white information. This was due to the fact that the earlier devices do not output color information - printing the received data performed by the method of thermal printing in facsimile (thermal) paper.

In a color fax, is generally used ink-jet printing - available send / receive, pre-editing of images without using a computer and print full-color images.

PC Fax. Fax has long been used as a reliable way to transmit information. Even after the advent of electronic methods of sending fax messages have not stopped using.

However, not always easy to read from a physical media, in some cases it is more useful in electronic form. This function allows you to display the fax as an e-mail message that can be opened on your computer.

Communication Speed ​​Facsimile - an important parameter that must be considered. The higher it is, the faster the device will hold the display transferred image.

Conclusion: if the facsimile is used frequently, then you should choose a model with a very high speed connections, and save documents in memory. However, keep in mind, and quality of the telephone line.

Characteristics

Minimum system requirements values

The minimum values ​​of the system requirements - the characteristics of personal computers, in which are able to work with the peripheral equipment. To perform certain required information processing resource of the computer - the operation associated with image processing.

The basic system requirements relates installed processor and RAM devices, wherein:

• To compute tasks sufficiently Pentium processor, Pentium II, Pentium III, Intel 486 or older generation.
• Memory (RAM) 512 to 1000 MB and above.
• USB port 2.0

Due to the fact that many printers are configured via the program - established manufacturer of equipment and included in the supply of equipment. Modern versions of popular operating systems allow printing directly via a standard print function.

Conclusion: if you as a source of information for the press is a modern computer, pay attention to the system requirements are required. However, older models can still be found in offices, schools. In these cases, consider the above information in the selection of the printing device.

CPU

The multifunction device processor controls the operation of the electronic components and functions:

• The liquid crystal display.
• Control Panel.
• Operating modes - sleep, standby ...
• Prepress processing (PostScript, PCL) - before sending an output, the processor calculates the resulting image / text, the time spent on processing depends on processor speed.

Despite the fact that the problem of printer and MFP is quite simple, the device also has a processor with a different frequency. Thus the redistribution component varies from 32 to 3000 MHz.

In this case, all in print tasks, moving at high speed.

Every year manufacturers are introducing increasingly performance processors having low power consumption at high performance. However, only the increase in CPU frequency does not determine an increase in productivity.

old and new generation of processor of the same clock frequency has a different index of performance because of the technology used in chip manufacturing.

Conclusion: if the MFP or printer is used in a small or a large office to display digital information on paper from multiple sources, it is recommended that the CPU frequency of 600 MHz.

For home use is not necessary to choose a model with a high processing speed.

Memory size

Tasks sent multifunction device or a printer, require RAM. Unlike conventional memory (HDD) provides instant access to information.

The more memory, the faster will be printing - before printing material posted placed in RAM and stored there until a new task or reboot / shutdown device.

LED and laser unlike inkjet models often equipped with RAM. The information processing speed is often dependent on this, since the inkjet model data rendering takes place directly on the computer.

Conclusion: The higher the value of the maximum amount of memory, the more users at the same time be sent to the printing task. As the number of connected users is expected to increase and RAM, otherwise the task will be carried out very slowly. Used similar equipment in offices, where daily tasks involve the conclusion of a large number of prints.

Memory element

Hard drive for many years is a place to store digital information. Some models are equipped with a hard disk. The speed of the device is significantly increased due to the fact that the information is not transmitted, and is read from the internal memory.

Main characteristics of the hard disk to printer - the volume. The greater the volume, the more information can be stored. However, the increase in volume increases the cost of construction.

Conclusion: if the model has a private memory, it is necessary to choose the option with the capacity of 60 GB. For domestic use and for printing small party has enough memory to 20 GB. For use in the need for high-performance models to be selected with a large amount of memory.

Operating Systems

work MacOS

Apple Inc. creates its products on a unique operating system MacOS. However, the original OS code is closed, so few manufacturers of printers and MFPs provide drivers for this operating system.

In MacOS several series, which should be considered. Typically, after an upgrade license the operating system to the latest version when there are serious errors in its structure, re-conduct the procedure obnovleniya will be difficult.

Conclusion: if the device is running on a Mac operating system, its support - an important parameter, which allows use of all printer and MFP functions.

Support for Windows

The Windows operating system - one of the most common. That is why almost all the models of printers and MFPs to work with her.

In Windows pre-installed features for printing. To ensure the work is sufficient to install the required drivers to the OS itself assembly often included drivers popular models in the absence of the installation files Microsoft provides driver downloads in the center obnovleniya.

Built-in functionality is usually enough to solve the fundamental problems. That is why many use features fast printing.

Among other things, we note that there were different versions of the OS. Current models of printers and MFPs support the version of Windows 8, or 10. Older versions of, for example, Windows 98 is no longer used, but nevertheless still occur.

If there is no support for Windows OS or a specific version arise. EXAMPLE problem situation, when the connected apparatus is determined or not determined correctly.

Support for Linux

The Linux operating system is very popular, but still share that falls on it, a little. Manufacturers do not always provide drivers for this operating system.

If your computer runs under Linux, consider the compatibility of the equipment.

data communication interfaces

To launch the MFP and printer is required, send the task with digital information. For the interaction of different interfaces are used.

The main interface types include the following:

Ethernet (RJ-45) - a common data interface in local area networks. All computers and laptops equipped with a similar interface. The advantages of the method include a data connection speed of 100 Mbit / s, the technology allows to connect the device to several sources combined into one network.

FireWire (IEEE 1394) - as well as an Ethernet port for LAN, data transfer up to 400 Mbit / s. But there is not all PCs are less raspostranen.

LPT - outdated interface, a parallel port for connecting printers to a PC.

RS-232 - outdated, a serial port is used to connect media devices - replaced by USB port.

USB - universal serial port (bus) is widely used to connect personal computers to peripheral equipment. It differs from other interfaces, the ability to provide power to peripheral equipment 5 volts.

Wi-Fi - wireless data transmission technology, has three standard IEEE 802.11 - b / g / n / are used for peripheral equipment, personal computers and mobile devices. Using this method of communication can significantly increase the functionality of the device - sending a print job from any device in the presence of them in WIFI module.

The range of wrap to 300 meters. Thus among devices receiving the signal and transmitting various possible obstacles including walls, but in this case the range of the reception and transmission is reduced.

Bluetooth - type of connection for wireless personal area networks designed to interface various peripheral devices, including printers. However, the data flow rate is low, the low reliability of created connection.

Advantages - a huge number of devices with Bluetooth wireless technology: tablets, phones, cameras.

infrared port - legacy wireless communication method by coupling devices via infrared beam - reception / transmission devices have to be in direct visibility, maximum transfer rate 5 Mbit / s. Infrared receiver is used as a remote control signal.

Conclusion: Considering wireless networks, look for a model with Wi-Fi module. When considering wire bonding methods obligatory presence of USB-ports.

For larger offices and enterprises suitable models with Ethernet interface (connector RJ45), FireWire - is to provide remote work with the printer, in this case, will be able to send a document over the Internet, while in any place.

USB version

There are several versions of the interface:

• Standard 1.1 - got quite a large spread immediately after the USB interface. A significant disadvantage of this compound standard relatively low speed connections, up to 12 Mbit / s. This index is often not enough to transfer large files - photographs and drawings.
• Standard 2.0 - it is most prevalent. Virtually all modern devices are equipped with 2.0 interface. Its features significant increase connection speed in comparison with the previous embodiment - theoretically 480 Mbit / s. In comparison with the previous standard speed has increased more than 30 times.
• Standard 3.0 - Version is gradually introduced into various devices. This embodiment differs from the preceding only in increasing the data flow rate. Speed ​​Indicator can reach 6 Gbit / s.

An example of a situation where an inkjet printer is used for printing large-format images. The time available to load the file may be quite large if you use an older version of the interface.

Conclusion: The interface standard is an important moment, as of this file transfer speed depends. For home use enough model with USB 2.0 version.

If the MFP is used for printing photos, drawings and other information, should choose a model with USB 3.0.

Connectivity Wi-Fi 802.11n

Wireless communication Wi-Fi 802.11n standard enables data transmission at high speed at a distance of up to 300 meters and speeds of up to 600 Mbit / s. operating frequency of 5 GHz and 2.4 GHz. But if the printer with WI-FI does not support the 802.11n standard that will connect to it via 802.11b or 802.11g fail. In case of supporting «N» outdated standards «b» and «g» accessible to connection to.

Print Settings

The time to output (print)

First print color and black and white. One of the parameters of the MFP and printer timing, different actions - the interval of time which is required a printer or an MFP to prepare and outputting first print cartridge using a color or black and white toner.

This indicator reflects how quickly will first print job after a similar problem.

Wherein:

• The printing speed in the monochrome mode, as a rule, slightly above - is not associated with complex processing of incoming information.
• At this rate, it affects the type of connection established - over Ethernet, unlike the USB port data is sent faster.
• Number of pages, the complexity of the information displayed - the presence of heavy graphics.
• Reheating furnace /

Conclusion: when the equipment every day for the frequent reception of several individual sheets, this figure is important. In this case, you should choose a model with a smaller interval of time to prepare. For the models used in the home, data output time do not pay attention.

First copy

When using the MFP is supposed to create copies. First copy depends on the total operation of the scanner and printer - takes 3 - 60 seconds. The speed of the scanner manufacturers indicate when scanning is A4 monochrome, many manufacturers specify the figure for Ink Save Mode - because, after training to work on the source code information is stored in memory, and it determines a significant reduction in printing time following copies.

Do not forget that the oven at continuous printing significantly heated, and the subsequent withdrawal of copies will need more time.

Conclusion: if you want to spend every day of the creation of 20 copies, in small batches, it is best to choose a model with minimal time to first copy.

Speed ​​printing and copying

Information output in the black-and-white mode is carried out fairly often, as most information to be disseminated are the text information. That is why the instruction is carried out print speeds for monochrome mode.

Typically, the print output speed is indicated for the A4, but in some cases it is A3. Print B / W mode is printed at high speed. This is due to the fact that the printer and the MFP is required to calculate the color transitions and tone of each point. There is also a mode to save ink, which speeds up the process of getting digital.

The inkjet models also indicated the print speed in black / white for sheets of A4 and A3. Manufacturers often use a specific ISO standard for specifying values.

The rate of appearance of the sheets depends on the following factors:

• The type of mechanism. Laser technology has a greater speed than, for example, ink jet technology.
• From the starting material and the sheet size output. Scaling functions allows for an increase in a document, for example, A6 to A3 sheet sheet. The larger the list, the more time is needed.
• From the amount of information on the sheet surface. Comparative Example - photos and text documents. For photos it takes longer than for a text document.
• Operating Mode: There are several modes of reception of the document, some are designed to produce high-quality results, the other to save ink and improve the speed of the equipment.
• The download speed information as the veil of the process loading information, processor speed, the amount of internal memory.

Speed ​​black and white copying text documents:

• Format A4 - from 2 to 130 sheets per minute
• Format A3 - from 2 to 100 sheets per minute

Speed ​​black and white printing text documents:

• Format A4 - 1 to 240 sheets per minute
• Format A3 - from 2 to 100 sheets per minute

• Format A4 - from 5 up to 138 pictures in a minute
• Format A3 - between 3 and 70 illustrations per minute

Conclusion: One of the most important indicators of the printer or MFP - print speed. He stated in the technical data sheet device. When choosing a printer, which works based on inkjet technology, should be considered in this section option.

Print speed color images

Print sheets is performed much faster than scanning source. This is due to the fact that the loading of the digital source code takes much less time than scanning. As a general rule, the rate determines how many sheets printed in one minute.
The rate depends on the print quality - the lower the quality and fewer dots per inch, the faster the print speed.

• Format A4 - from 1 to 51 images per minute
• Format A3 - from 0.5 to 24 images per minute

Copy speed color images

Copying speed in color under consideration format determines how many pages a multifunctional device can print per minute.

• Format A4 - 1 to 130 copies per minute
• Format A3 - from 1 to 46 copies per minute

It should highlight the points stated below:

• Creating A4 copies performed pretty quickly, if provided for printing a large number of standard formats, then consider this option.
• A3 is not as populyareny dokumentoborota used to, but in some cases, color copying speed of these sheets is essential. A3 is twice the previous size, which determines an increase in the time required for the printing process.

If printing is performed in economy mode, it consumes less time to perform the procedure than at the normal operation.

Conclusion: The speed color copying - an important indicator when using the device for the needs of large and small office, but at home it does not matter. Color printing always takes more time than black and white.

Maximum resolution on X and Y to print color or black and white format

value of the maximum resolution for printing allocated horizontally and vertically:

1. The maximum print resolution of X varies in the range of 148 to 9600 dpi in the case of displaying information in color, and from 148 to 9600 dpi for black and white information.
   

   Indicator determines how many dots per inch rasplozhen sheet in a horizontal plane.

   
   Modern models measure approximately 4800 dpi, in the previously popular laser models that value to 2400 dpi.
2. The maximum resolution of the print to the coordinate Y corresponds to the previous value for color printing in the range of 148 to 9600 dpi, for black-and-white value ranges from 60 to 9600 dpi.

This rate determines how accurately the information displayed on the worksheet. The more dots per inch, the greater the nuances (fine detail) is displayed on a sheet at printing.

Fax resolution along the X and Y: the maximum values

When sending documents via facsimile are also taken into account that a maximum resolution can be displayed. Determination of this parameter occurs in two coordinates: X and Y. Display resolution determined by the measuring unit displays the number of points in the calculation of one inch.

Refer to this measurement as the dpi:

1. By X coordinate resolution in the range of 200 to 1200 dpi.
2. According to the resolution of the Y coordinate in the range from 100 to 3000 dpi.

The higher the value, the better the result. However, it is important to note that both devices must have the same maximum performance quality of the transmitted image by facsimile.

Conclusion: The higher the value, the better. It should be borne in mind that the increase of the maximum resolution increases the cost of equipment.

Number of cartridges

For applying the paint onto the surface of the sheets used cartridges. Improper use and refueling there is a possibility of failure of the cartridge.

The number of installed cartridges - defines the method for mixing colors when printing the printer.

All printing devices conventionally divided into several groups:

• Printing CMYK (blue, red, yellow, black). In the LED and laser models, usually, the number of cartridges is equal to the number of colors used. This point is determined by the fact that each cartridge is placed in the toner with a 100% color. However, one should not confuse the concept of color and hue: no models that contain more than 6500 cartridges.
• Printing on RGB (red, green, blue). The number of installed print cartridges in inkjet models different from the laser, in addition to 100% -x colors used cartridges with the colors of light colors.
  

  Most models have a clear division of cartridges to print in color and monochrome mode.

  Such an option is most prevalent. Devices used ink saving function when ispolzyutsya exceptionally bright colors black cartridges.

Separation by color cartridge greatly simplifies the use of the printer or MFP - when it ends with a black ink cartridge, color is used at the same time before the end of the ink.

Conclusion: If you select should pay attention to models with a division of cartridges to print in color and monochrome. This makes it possible to significantly reduce the cash cost of cartridges.

For domestic use enough standard colors 4-6 cartridges to solve complex office or other problems use models with a large number of cartridges. Increasing the number of judges that the device will use more colors for printing.

However, it is worth remembering that the ink is consumed unevenly (magenta, light magenta - red (magenta) spent most).

color depth

Scanner for transmitting information using several color discharges. As a rule, many models are created for 24-bit color technology transfer, 8 bits for each color. Parameter is specified in the technical data in the passport data devices.

In practice, note the difference between the 24-bit system and one that uses more bits per color, is quite difficult. This is done using special equipment.

Conclusion: for normal office or home use enough model, 24-bit color transmission system. When the printer or multifunctional device is used for other purposes, e.g., for transmitting complex graphics, it is useful to use other models with a large number of bits.

Drop: the minimum amount of

In complex images many transitions from one shade to another. The more smooth transition, the better the quality of the result. The minimum value of drop volume affects the quality of halftone and color transition.

The smaller the value under consideration, the better the image quality will. Index ranges from 1 to 35 pl - unit picoliter - one millionth of the calculation of one million liters.

Conclusion: The models used in the domestic sufficient minimum drop volume of about 10-15 pl. To conduct printing photos should choose a model with the minimum drop volume because it affects the quality of the printing.

shades of gray

Even if you select the print mode, only in gray tones it is possible to transfer all the features of the image, as some colors appear vivid gradient, others darker. The more shades of gray, the better the quality of the information displayed when printing. With increasing number of shades considerably increases the degree of detail images when printing black-and-white cartridge.

Often transmitted 256 shades of black color that corresponds to one channel of 24-bit color.

Conclusion: In order to allow for the use of only black ink cartridges it will transmit a greater number of shades. Otherwise, the resulting images will be self-colored, gradient transition is displayed.

The amount of information output in one month

Each device a certain period of operation. Determined by various methods, often indicated by the manufacturer in the passport. The service life of MFPs and printers, is determined in the number of printed pages per month. The special features of the definition of this indicator include the following:

• The maximum indicator of the number of printed pages per month - a value that determines the possible amount of received pages for the selected period of time without reducing the overall lifetime.
• Typically, such a value is taken with a substantial margin. This point allows to protect the device from premature failure.
• The higher monthly printing possible, the device has greater reliability. In this figures the container inlet and outlet of the tray, the cartridge operation period determined also depending on the value specified.

Conclusion: for office use, use patterns, with the index of 100 to 2 000 000 potential mark for one month. Suitable for home use models, with the number of prints in the several hundreds.

Fonts PCL, PPDS, PostScript: the number of installed fonts

To recognize text document printing device has pre-installed fonts. In considering this question, the following:

• Fonts PLC - established set contains from 3 to 181 fonts. This type of font used in the description pages. Independently carry out the installation of fonts is almost impossible.
• PPDS fonts - are also used in the description pages. A set of similar fonts consists of 39-44 characters.
• Fonts PostScript - are used in the description of pages, a set consists of 14-251 characters.
• The larger the font, the faster the print pages.

In certain cases specified in the device data sheet. The higher the value, the better.

Number of colors

A significant indicator of the number of colors used in printing:

• The inkjet models from four to dvenadtsatitsvetnuyu printing. As a rule, monochrome printing is performed using the black ink cartridge. Depending on the amount of ink held color change. Color print cartridges used with the three RGB primary colors.
• In some models, designed for professional printing color images and documents, ink cartridges with more than 6-Tew 100% color and the same shades.
• The color laser models used cartridges with four colors.

The number of colors is specified in the passport, which is attached to the device at purchase.

Conclusion: the more colors, the better. This applies to models designed for printing photographs. The larger the number of colors used to display digital information on paper allows you to transfer the color better.

Printing on both sides in the automatic mode

In order to save printing paper is often carried out from two sides of the sheet. Run it manually is a long process, shall be considered (to know) with the edge of the sheet begins printing. To speed up the process printers added feature automatic two-sided printing is set in the program (eg, Photoshop, Corel Draw, Word) when you send the print job.

Automatic two-sided printing (duplex) - printing on the sheet held in step 2, after printing on one side of the sheet and pass through the furnace does not support It is fed to the output tray, and passes through the roller system in such a way that the reverse side of the sheet is to face photoconductor drum.

Information output on both sides in the automatic mode is often organized by using multiple toner deposition systems, i.e. for each side of the sheet. This design feature significantly increases efficiency, reduces time spent on printing, but increases the cost of the printer or MFP.

paper Options

Acceptable formats

All sheets used for printing, have standard dimensions, which have been named certain formats. Some models of printers and MFPs work exclusively with one or more of the most common formats, and other supporting more.

The basic formats:

• Models that are designed exclusively for printing photographs only support A6. When using such a printer is obtained pictures size of 10 by 15 centimeters. As a rule, these models are connected directly to the camera or to the computer, from which will be held download images.
• The most common A4 format. Size-fits-21H29,7 see, in offices, schools and homes. If not clearly specified requirements regarding the format, then this option is suitable to a greater extent. Also note that such models are most often used at home, because of a low cost and performance.
• A3 - 42H60 see often found in offices, is used to produce non-standard size forms, magazines, classified ads. 2 times greater than the A4 format size, is used not only in offices, but also in schools, to create schedules, etc.
• A1 and A0 are used in wide-format inkjet printers to create drawings in technical training institutions, as well as enterprises whose activities are connected with complex graphics. It is used very rarely.
  

  Printers that are able to print on paper of this size are expensive and only purchased to perform professional tasks.

For home use it is advisable to acquire A4 printers. Other variants are suitable solely under individual conditions, e.g., during the occupation of photographs, technical drawings and so on.

Conclusion: possible format determined by the size of the sheet feeding tray or the host, as well as the characteristics specified in the passport. Some models are used for custom printing sheets (e.g., A3 +), to which the tray has the ability to change size.

roll width

Some devices are intended for the application of information on sheets with non-standard dimensions. In this case the feeder in certain situations to use rolls minimized. Often the sheet width greatly exceeds A0 format.

Conclusion: if you want to use a custom paper size, you should take into account the maximum value of the width of the roll. Example - drawing printing, large posters and so on.

Paper density

In addition to the linear dimensions of the paper there is a record as the density. The given value ranges from 20 to 1190 g / m².

At the same time, we note:

• Low density indicator determines the high likelihood that the paper is wrinkled clips during capture. If this happens, then there is a probability of occurrence of a significant fault.
• Thick paper is not bent during the inking process.

This rate is specified in the device data sheet.

Conclusion: almost all models of conduct printing on paper with a standard indicator of 80g / m density². If the provided printing on non-standard paper density, it is necessary to find information about what rules have the device in question.

Paper Feed Print

It should take into account the total volume of securities held in the input tray. The most suitable value for the number of paper in the tray depends on the daily print volume. When you select should be noted that the tray is sufficient paper for a few days it should be stored.

For home and small office enough to the tray was placed between 100 and 150 sheets. For the average office capacity paper tray 300-500 sheets for large offices - from 1000 sheets and more.

Consider the possibility of extending the maximum amount of paper feeding by means of additional modules - up to 4,000 sheets.

Capacity of the manual feed tray

Not always seal involves the use of plain paper. In some cases, a special material, for example: paper with a non-standard density, thermo, envelopes. This tray has a higher priority, so when using the manual feed tray conventional tray is not used.

The main parameter of capacity - from 1 up to 1000 pcs. If the tray is not paper, it will automatically begin to work the system a bottom feeder.

Conclusion: The paper tray capacity, which is used to feed in the manual mode is taken into account only in the case of frequent use of non-standard paper. In other situations, this setting does not matter.

Output of paper (maximum, standard)

MFP or printer design provides for a special tray that collects paper. Some designs can significantly enhance the ability through the use of optional trays. This feature determines the change of the maximum amount of accumulated sheets is increased or decreased as necessary.

The cost models stored in the tray 50 to 150 sheets, a professional model - from 500 to 1,000 sheets.

Conclusion: pay attention to this indicator should be only in the case where printing is performed on a large scale. In other cases, when choosing not worth paying attention to such indicators.

Using glossy paper

Glossy paper is used quite often when you print a variety of information. To display a bright and interesting print many choose this grade of paper. It has the following features:

• It has a nice shine.
• High density determines the long service life of paper.
• paper structure determines that the ink is very well absorbed by the structure.

Considering the above list, we note that the glossy paper is perfect for photo.

Conclusion: if the device is often used to create the pictures, the ability to print on glossy paper - almost irreplaceable function. In other cases, the use of glossy paper is not significant.

scanner Specifications

Scanner resolution Y and X

Multifunction device has a scanner that carries out transfers of information into digital. At the same time, we note:

• The coordinate X represents the horizontal plane, the coordinate Y - Vertical
• The stroke of the stepper motor determines the accuracy of the scanning mechanism and authorization.
• The value of the mechanical scanner resolution are almost always over-optical values ​​used fotolineyki.
• According to the X-axis scanner resolution rate varies from 200 to 9600 dpi. Optical resolution can be in the range of 600 to 1200 dpi.
• By permission indicator Y axis varies within the range from 200 to 19 200 dpi.
• To obtain sufficient image quality 1,000 dpi for each coordinate.

Conclusion: The higher the resolution, the better. However, higher values ​​can be achieved only with the use of modern equipment, which significantly increases the cost of construction. For home and general office use enough so that the scanner had a resolution of at least 500 dpi for one of the coordinates.

Scanner resolution in X and Y (improved)

The value of optical resolution in the vertical and horizontal axis determines how many pixels in line with the photosensitive element.

The special features of the interpolation method may include:

• The resulting image are applied to the intermediate points.
• Brightness and color dots intermediate value depends on the color and brightness points that are obtained by an optical method.
• As a result of combining the density of points is increased by one inch, which largely improves the image quality.

In some cases, use an interpolation method for improving the quality of the image as possible in order to increase the number of parts. It is also possible to carry out the smoothing of contrast transitions.

Conclusion: the function in question is very useful, because it determines the improvement of the quality of the printing result. In this case, even a model for home use brings an improved version of the resulting scan.

Values ​​scanning along axes X and Y

The maximum size of the document you want to scan, the coordinates are measured:

1. X - coordinate in the horizontal plane. The device size is possible, does not coincide with the standards. For X-axis component ranges 126-9140 millimeters.
2. Y - the maximum size of the vertical plane. For this coordinate value varies 256-2000000 millimeters.

This is an important indicator, since it determines what size the document may be scanned.

Conclusion: when buying a multifunction device should be considered is what size is a special place where the original document is placed. For domestic use become models that have a small scanning value. For professional use should be selected models that are larger scan.

Device auto originals

Automatic feeding of originals during scanning can significantly improve the performance of the printer or MFP. If you put it in a stack of sheets to be selected as a source, the sheets will be supplied without an operator. In this case, the following ADF model source:

1. Unilateral - the simplest embodiment, which enables scanning of the sheet from one side only. This mechanism is very common, as it has a simple structure and little, cost.
2. Bilateral - automatic feed is performed for printing on both sides. Encountered such a scenario design is quite rare. Such automatic document allows several times to increase productivity.

This design allows several times to increase the performance of the device. It is therefore suited for office use model with automatic feeder.

Auto originals carried out by using a mechanical element. Can be arranged in various ways, among them some are compact, while others have a higher performance. Therefore, the choice should take into account that some of the original automatic document used.

As a rule, manual feed source code is likely mistakes: improper placement of the sheet, changing its original state. With automatic feeding eliminates the possibility of mistakes when filing source.

One of the most important indicators is the capacity of the ADF originals for scanning procedures. Most of the models on sale has capacitance component of 10 to 50 sheets. In most cases this is enough, but if the work is provided with a large number of documents, then this may not be enough.

Conclusion: to use the printer and MFP in the office should select a model with a large capacity paper feed mechanism automatically. There are models that have a capacity of up to 300 sheets to organize ADF. For the home and lack of use is enough to choose a model that has a tray to send about 30 sheets.

Scanner sensor: the division into groups

Multifunction device has a scanner function that allows you to translate documents into electronic information, or to carry out the creation of a large number of copies. In order to carry out such work design should have some type of sensor. Two scanner sensor variants can be identified:

CIS or contact sensor the image is presented to the line defined by photocells, which often has a length of document being scanned.

During operation, scanning sensor movement occurs under the glass throughout the length of the document, the transmitted line by line. In order to highlight the source code uses a set of LEDs which are located close to the document, and are also part of the movable member.

This scanner uses very popular, as it has a simple design, low weight and low cost.

CDD or a charge coupled device is an integrated circuit, which consists of a light-sensitive line. Source code used for transmission-type optical system having a structure of a lens and mirror.

In this case, the original lighting held fluorescent lamp. The advantages of the sensor under consideration include a high depth of field, as well as high color rendition. Even when scanning crumpled sheets can get sharp images with good clarity. Professional scanners have exactly CDD sensor.

However, the presence of the optical system defines a large design thickness, the high cost when compared with the previous sensor.

When considering what kind of scanning probe solution to a greater extent, we note that the model intended for domestic use, are CIS sensor.

Conclusion: The type of sensor used - an important metric that determines the quality of the result when scanning. Find out what kind of sensor at the MFP, it is possible with the technical passport.

Suitable for home use model, which consists of sensor CIS, and for use in small or large office complex to scan graphics and documents in poor condition suitable CDD model type.

The time allowed for scanning (cvetn., H / w)

Scanning speed - an important parameter that is taken into account in the selection of a multifunctional device. This rate depends on what is the size of the source material, and a resolution. Many manufacturers specify this value is conducted for A4-size sheet scanning.

At this scanning speed is measured as follows:

• Number of pages of time (one minute) - the measurement gives accurate results only if you need to get multiple copies of the same source.
• The time required to make a single copy. This point is quite important when considering the performance of multi-function device.

This index is indicated in the passport.

Conclusion: The scanning speed is important when using the printer or MFP for commercial purposes, or when using the device in a small or a large office. The time allowed for scanning, color and black-and-white source code are slightly different.

The maximum dimensions of the original

A multifunctional device which can also hold copies creation, has a specific structural element where the object to be scanned is located. The dimensions of this structural element determines the maximum size of the original. Most of the models allows to scan A4 and A3.

A4 - the most common sheet that is used to create forms, and many other documents. If there are no special requirements for publication, the suitable model for the scanning of A4 only. Still there is A3, which has a small spread.

Professional models allow for scanning sheets whose dimensions correspond to the formats A1 and A0. These multifunction devices have larger dimensions.

copier Features

scaling

Multifunction devices are able to carry out the creation of copies of the original document. In some cases, there is need to increase the size of the original document. For example A4 sheet scanning and increasing the fragment thereof to the sheet A3. Most of the models are able to carry out an increase in the source document to 25-400%.

Conclusion: The function is quite popular as greatly simplifies the process of increasing the original document. If not, then many spend increase by means of a special program and then you print.

For instance, when the A3 sheet is required to transfer the information on an A4 sheet. Most of the models is being reduced to 25-400% of the original document.

Conclusion: the function in question is useful because it allows free use of the software to carry out a reduction of the original document. For use in the home, she does not really matter, but if the multifunction device is purchased for professional applications - it would be superfluous.

step zoom

Some mechanisms output of digital information on paper have the ability to make copies with scaling. In this case, an important indicator - zoom step. In most embodiments, the scale is adjusted in increments of 1%.

Scaling is performed without degrading the quality of the result due to the special scanning system. It should be borne in mind that at the time of scaling the output paper displays only a portion of the original document. This occurs only if the source code format matches the format of the output sheet.

Conclusion: The accuracy of the regulation, which copy will be displayed, determines the result. The smaller the pitch, the higher the functionality of the device.

Copy Resolution X and Y, color and black and white copies

Among the many options you need to consider the maximum resolution. In this case, we distinguish the following important points:

X coordinate specifies the maximum resolution in the horizontal axis. This figure is indicated by the number of display dots when the surface area of ​​one inch. The higher the score, the more nuanced device displays on paper.

The indicator consists of a printer and scanner resolution. Laser and LED devices have a resolution, which is dependent on printer capabilities. For a monochrome display and color display is significantly different.

Y coordinate determines the resolution in the vertical axis. This figure corresponds to the previous one, resolution color printing within the range of 244 to 4800 dpi, and black and white from 200 to 4800 dpi.

Such values ​​are directly affect the quality of the result when scanning a document or a photograph, picture or other source. Therefore, you should pay special attention to this indicator.

Conclusion: one parameter that determines the quality of the scan source code is to allow vertical and horizontal axis. Manufacturers spend an indication of this information is reflected in the generated ID.

The number of copies per cycle

Multifunction device is used to create copies. For one copy cycle can be carried out creating several documents. All current models allow you to select the number of copies, and the maximum number reaches 2 to 9999 pieces.

Conclusion: The frequent use of the scanner function similar setting is essential. The larger the maximum value, the better.

Noise level

Some printer models create problems during the idle emitting noise in standby mode. Depending on the model, the noise level is in the range from 0 to 63 dB.

Its causes operation of the cooling system, power supply and other components. Despite the fact that in standby mode the noise level is much lower than during operation, this creates a lot of problems to others.

The indicator zero noise level in the standby mode, if the device manufacturer provides the power saving mode. During the idle unit in sleep mode and calms down, and returns to the operating mode within a few seconds by pressing.

Conclusion: If you select the model should pay attention to the considered parameter, since it determines the ease of use of the equipment. In many models implemented zero noise, but there is a possibility of regularly switching on the cooling system.

During operation, there is also the likelihood of noise. It is in the range of 6 to 75 dB. Due to the fact that during some of the design elements are movable, and is used for cooling fan system. In some cases, due to a large noise device is installed in a separate room.

The noise level is dependent on a variety of features:

• From the presence or the presence of the cooling system. It is necessary in the case of a high productivity since continuous operation many design elements heat up considerably.
• From construction year of release. Over time, the mechanical parts wear out, resulting in noise. Every year the used technology allows a large extent to improve the design and make it work more quiet.

The noise level is usually specified in the device data sheet. In this case, the manufacturer shall be measured at work in certain conditions.

Conclusion: In order to using the big problems did not arise in the consideration of the passport specifications should pay attention to the noise level during operation.

Warm-up time

After the first start the printer and MFP time required for heating the oven, since the toner deposition is carried out only when a certain temperature. heating time is from 30 seconds to 2 minutes.

When the printer is used rarely, it goes into sleep mode.

Conclusion: if the design provides for mandatory warm-up parts, the heating time - an important indicator. When you start working after a long downtime in some cases have to wait considerably.

Display information

Despite the fact that the printing device is only used for the transfer of digital information on paper, expensive models special screen on which various information is displayed. You can use it to solve the following tasks:

• To display and set the basic print setting parameters and operation modes.
• To display text, graphics device status.
• Or scanned for displaying the downloaded document image.
• To view the photos, which were transferred from the camera.
• To work on editing photos, their location on the same sheet, and so on.

Large printers and MFPs can have large displays with screen sizes. The larger the diagonal, the easier it is to work.

In some cases, for example, when the printer is used directly for printing photos from a camera, the presence of the screen allows you to determine how will look about the print result. However, on the model of the performance of the presence or absence of the screen has no effect.

Conclusion: if the model has a color screen, the screen size is an important parameter. The higher it is, the easier it is to use the equipment. Also, with an increase in the screen size it can display more.

The number of connectors for external modules and free slots

Some models allow for empowerment as necessary. To do this, the design of add special slots, which are often used to set the following modules:

1. The print server.
2. HDD. Note that the device must support the ability to install the internal memory.
3. The module with the additional interfaces. Many models of printers and MFPs have the necessary local functionality, but small opportunities to connect.

Some sales kits are already built-ins, others only slot for expansion. Depending on what features are needed, it is possible to carry out the replacement of modules.

Conclusion: The presence of slots for plug-ins - a useful feature. It stipulates the possibility of expanding the device functionality. However, it should be borne in mind that the slots can be widely or highly directional.

Power consumption in the standby mode, when working

The printing device according to the printing technology consumes power reaches up to 15kW:

• Consumer power in standby mode. In the office of the printer or MFP is left in working order throughout the day as well as the triggering device takes time. Consumer power may vary within the range from 0.1 to 1200 Watts - a laser printer includes a furnace momentarily idle.
• Consumer power is always higher than that in the standby mode. In this figure varies from 2.5 to 15,000 watts. Some tasks require more energy.

Power consumption at the time of waiting depends on the following factors:

• Is there a design cooling system or furnace. It can work with simple equipment as fan operation comes from the temperature of the system.
• Is there a system to save energy.
  

  Some manufacturers care about is that the device does not consume a lot of energy, which was created by a special saving mode.

  
  For this printer and MFP on downtime does not work, but becomes active for a few seconds when needed.

Power consumption at the time of the work depends on the following factors:

Printing on cards

When you use the printer often spend creating cards. However, it is worth remembering that the card is made of thick paper. Card is used to create the following materials:

• Coupons.
• Index cards.
• Postcards.

In order to be able to use the card device must have a special tray for their submission, as well as a function to change the print size.

Printing on Envelopes

Printers are often used to apply a variety of textual information and images on the surface of the envelope. In order to be able to use the model to solve this problem it should have a tray designed for feeding envelopes. Also part of the program should allow changes to the print size.

Printing on matte paper

Matte enjoys quite popular. Bright and interesting imprint can be obtained by using matte paper types. The special features matte paper are:

• It has a high rate of absorption.
• It dries quickly.
• The surface does not reflect light.

This type of paper is also applicable to display still pictures of different business cards, postcards, and so forth.

Almost all models of printers and MFPs can cause the ink to the paper matte type.

Printing Transparencies

Film is used for printing and slide presentations, mainly using laser technology. Foil is easy to operate with standard size sheets printed, deposited paint is not washed off, but withstand rough mechanical friction.

When searching for models for printing on film, be aware not to apply the mechanism of the printer oil Fuser (oven) - these printers are capable of printing on films, but with a small amount of printing out system.

Printing on roll

In most cases, the paper used in piece form, since the tray and the pickup uses only single sheets. However, in some devices, it is possible to use paper as a roll. After applying the ink sheet portion is cut from the roll.

The roll is kept large format paper and photo paper (the paper is not afraid of the light, in this case - it is high gloss). This simplifies handling and operation.

Conclusion: if the printer must have a better performance, you should choose the models that work with rolls.

Printing on photo paper

Photographic paper is used for printing photographs. It is worth noting that the quality of the image depends not only on the printer model, but also on the characteristics of the selected paper. Photographic has qualities that allow the picture display - coated paper structure special enamel instantly absorbed ink, not allowing the dye to leak out and spread out on sheet.

If provided frequent use of the device for photo printing, the ability to use paper - an important characteristic. In other cases, the presence of such a function is not necessary.

Printing on labels

Labels are created on a particular paper, which is not like the others. It is used for application information on products by, for example, wheels, plastic bottles and so on.

Labels can have different sizes, the paper density, type of surface. Printers and MFPs that specialize in the creation of labels, often can not be used for printing on plain paper.

Conclusion: The possibility of carrying out work on the application of ink on the label - the specific function of which is necessary in rare cases.

Printing photos

After the appearance of digital cameras popularity of color printers and MFPs significantly increased. This is due to the fact that it is possible to carry out direct printing without significant cost.

Current models allow for printing of photos on the quality level that corresponds to the level of quality prints from a photo lab. They are based on inkjet or sublimation technology. In order to get a similar image is used more than 6 colors.

This point defines what is unnecessary to carry out the connection of the camera to the computer. In order to facilitate the operation of the device printing device may have a memory card slot.

Conclusion: if the print provides a large number of photos, you need to choose the model that are designed for this purpose. This is due to the fact that additional functions related to photo printing, can increase the quality of the result and greatly enhance functionality.
