-The design of the device completely and completely repeats the devices for 2022-3000. It is enough to disassemble and make sure that there are no differences from state employees on 123 cartridges, for example, HP DeskJet 2130. Well, they added some kind of CISS. Why such money? All the same, it normally works on the strength of one year, then either the heads fail, since they are thermal jet and do not differ in any way from cartridges for 700. -Often the black ink filling tube in the print head gets clogged, though the language does not dare to call it that - this is an ordinary cartridge that many people love to refill syringes so much, just for a lot of money. -The paper capture mechanism also causes a lot of problems: either the rollers get greasy, but this is half the trouble . Most often, the planetary gear to these rollers falls apart, the gears cannot engage normally due to backlash. That's right, this system is not designed for permanent printing. -There is no pump, the ink merges directly into the printer tray through the cleaning pad, and knowing the insidious HP pigment, which eventually turns into resin, the parking unit is also a candidate for departure. -Risks on the encoder tape are applied with water-soluble paint! In the 21st century paint, Carl! You can not wipe it even with distilled water, it will be washed off only on the way. Therefore, when parsing with our hands, we do not touch it at all. Otherwise "paper jam error". I do not recommend this model in any way. Better take the same 2130, learn how to refill cartridges, something will break, just throw it away and buy the same one. 2500. not 10000. And for reliable permanent printing, there is nothing better than Epson with a factory CISS. Where does so much information come from? I work in the service, this trash is constantly carried, as well as his colleague Canon G3400. And if problems occur during the warranty period, HP replaces them entirely or issues a certificate of impossibility of repair. Realizing what they had done, the marketing department even reduced the prices for a set of printheads to 1500, so that it would not be excruciatingly painful to give half the cost of the MFP when they just went into series.
