Max resolution

The maximum resolution of the image to be printed. It is usually indicated by two numbers indicating the number of dots per inch (dpi) horizontally and vertically, for example 1200x600. The detail of the image depends on this parameter – the higher the resolution, the more fine details the printer is able to convey and the better their image will be. High print resolution is important, foremost, operating with graphic material; low resolution is sufficient for high-quality text display. So there are the following options: 600x600, 1200x600, 1200x1200, 1800x600, 2400x600, 2400x1200, 2400x2400, 4800x600, 4800x1200, 4800x2400, 5760, and higher print resolutions.

First page print

The time passed from pressing the Copy button to the completion of the first copy in MFPs. Typically specified for low quality black and white printing on A4 paper. The time for the first copy to be released is the longest (because of the time to prepare for work and scan the document); subsequent copies of the same document are printed much faster. Fast first copy time is important if you have to copy documents frequently.

B/W copy

Black and white copy speed – the number of copies of one page that the MFP can produce in 1 minute. Typically indicated for poor print quality. This option is important if you often need to make many copies of a single document.

B/W printing

The number of pages the printer can produce per minute in black and white mode. Typically indicated for low print quality, higher print quality takes longer. This setting is important if you need to frequently print text documents.

Monthly Duty Cycle

The maximum number of pages that the MFP can print in a month while remaining fully operational.

Cartridge model

Types of cartridges (both black&white and colour) used in the MFP. Some models of the MFP are able to work with third-party cartridges, but this feature usually refers to undocumented, and the manufacturer's warranty applies only to specific types of cartridges. So, use third-party compatible cartridge models with caution.

Higher capacity cartridge

The MFP cartridge is designed for a certain duty cycle. However, the device compatibility with different cartridges sometimes allows you to install a cartridge with higher capacity, which can result in more pages being printed. These models with the option to expand the print cycle that are included in this paragraph.

Display

The type of display provided in the design of the MFP. This parameter is indicated by two points — colour (monochrome or colour display), as well as the availability of a touch screen(if only spec 'coloured' is indicated, then the display is non-touch).

Chroma determines the features of the image on the display. Monochrome (black and white) displays allow you to show a lot of different information, and are inexpensive. On the other hand, such a display is poorly suited for viewing drawings and photos sent for printing, the results of scanning pictures, etc. — for such purposes it is better to use more expensive, but more functional colour displays.

As for touch displays, they provide additional convenience in management and expand its capabilities. Various controls can be displayed on such a display — sliders, lists, text menus, etc.; operating them with touches on the display is easier than using traditional control panels with hardware buttons. On the other hand, the presence of a sensor affects the cost of the display, and it makes sense to use this feature mainly in advanced MFPs with an abundance of additional functions.

Grammage (max)

The maximum grammage that the MFP can print on. The grammage of the paper depends primarily on its thickness; thick paper is strong, but if it is thicker than allowed by MFP's manufacturer, the paper feeder simply cannot handle such sheets.
