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.

Photo printing

Printer's print rate in photographic (highest) quality. Unlike other similar parameters, in this case the speed is usually indicated for a 10x15 sheet (A6 as the most popular format for photos). In addition, photo printing speed is not expressed in pages per minute, but in seconds per page, because such printing takes a lot of time. This option is worth paying attention to if you plan to print photos frequently.

Monthly Duty Cycle

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

Black Ink Page Yield

Approximate number of pages that the MFP can print in black and white mode without replacing the cartridge. In fact, this greatly depends on the specs of the images to print, so the actual resource may greatly differ from the claimed one in one way or another. Nevertheless, according to this indicator, it is quite possible to evaluate the capabilities of the MFP and compare it with other models.

Colour Ink Page Yield

Approximate number of pages that the MFP can print in colour mode without replacing the cartridge. In fact, this greatly depends on the specs of the images to print, so the actual resource may greatly differ from the claimed one in one way or another. Nevertheless, according to this indicator, it is quite possible to evaluate the capabilities of the MFP and compare it with other models.

Built-in CISS

The device has a built-in CISS — a continuous ink supply system. Instead of cartridges, such MFPs use external tanks with ink being pumped to the print heads. This allows you to reduce the cost of consumables: one refill of CISS is much cheaper than several replacement cartridges for the same printing page volumes. And refilling such systems is cheaper than changing the cartridge.

The availability of CISS is especially important if you intend to print often and in large volumes. Note that such devices are available in the form of external attachments; however, the integrated system is more convenient and safer — you do not need to mess with its installation, and the risk of incompatibilities and failures is minimal.

Ink Type

— Pigment. Ink based on pigments — solid dyes, which are diluted in the form of microparticles in a liquid filler to a state of suspension. Compared to more popular water-based inks, these inks are noticeably more expensive, and the finished image may turn out to be somewhat less bright (compared to printing with water-based dye on the same MFP). On the other hand, pigment ink gives higher detail, which is especially important for photo printing. In addition, finished images resist humidity better and do not fade as quickly in bright light — this resistance is not enough for outdoor use, but indoors such prints can be stored for a very long time.

— Water soluble. Inks based on water-soluble dyes allow achieving high realism of colour reproduction in colour printing, they are well absorbed into the deep layers of paper and are cheaper than pigment inks. Also, water-soluble ink does not dry as quickly in the cartridge or print head of the MFP. They are recommended for use with inkjet paper — ordinary thin paper strongly absorbs dropsy, which can cause ink to show through on the back of the sheet. At the same time, water-soluble ink is afraid of moisture and direct exposure to ultraviolet light — when water gets on, the paint on paper “floats”, and it fades under the sun light.

— Pigmented / water soluble. Some MFPs have a print head that allows you to print with two types of ink at once. A common case is when their black cartridge is filled with pigment...ink, and the colour one is filled with water-soluble ink.

Number of cartridges

The amount of cartridges required for the full operation of the MFP. In black and white devices, usually, one cartridge is installed. For colour printing, at least 4 colours are required (CMYK colour scheme), however, cartridges in such devices can be installed as 4(one for each colour), or only 2 — black and colour. The last one is essentially three multi-coloured cartridges in one case; This design somewhat reduces the cost, but creates certain inconveniences: when the ink of one colour is empty, the entire colour cartridge becomes inoperative. However, this disadvantage is not critical if the possibility of refueling is provided.

There are printers designed for more than 4 cartridges. This design means that this model uses one of the extended colour schemes; this, on the one hand, contributes to high-quality colour reproduction, on the other hand, it significantly affects the price.

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.
