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.
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.
CPU frequency
The clock speed of the processor installed in the MFP. Theoretically, the higher this indicator, the faster the device is able to handle with various tasks; high performance is especially important when printing high quality images, scanning at high resolutions, etc. However, in fact, the capabilities of the MFP, in addition to the processor, depend on a number of other specs, and this point is more for reference than practically significant, and when choosing, it is worth focus on more obvious performance specs (copy speed, print speed, etc.).
Scanner Colour Depth
The colour depth supported by the MFP scanner. This setting determines the number of colour shades that the device can recognize. Therefore, the overall quality of the scan directly depends on it (although other features of the device also affect this quality).
Of course, it makes sense to be focused primarily in colour depth if you plan to intensively use the scanner for full-colour images like photos, paintings, etc. If the MFP is purchased mainly for documents, where the maximum variety of colours is the logo on the letterhead or the stamp, it barely makes sense to pay special attention to this spec.
As for the colour depth, we note that the total number of recognizable shades can be determined using the formula “two to the power of the number of bits”. For example, a 24-bit scanner will recognize 2^24 = 16.7 million colours (approximately). This value is considered quite sufficient for everyday use, and 36-bit is also sufficient for relatively simple work tasks such as printing brochures and other images that do not require high colour fidelity. But for professional work with colour, you should choose more impressive scanners; in the most advanced models, the colour depth can reach 60 bits.
Fax storage
The maximum amount of received fax pages (see Built-in Fax) that the MFP can store in its own memory without being printed. This feature allows you, among other things, to output saved pages to a PC, thus saving paper, to receive faxes when there is no paper, and so on.
Feed tray
The maximum number of sheets that can be loaded into the MFP feeder at one time. Blank paper is taken from the feed tray for subsequent printing; the more sheets fit there, the less often you will have to reload the MFP with blank paper.
