this printer is programmed to block all its functions when using cartridges other than those sold by HP or refilled. For this purpose a chip is included in the cartridge which is capable of detecting a foreign cartridge. A meter lets you do some impressions with, then an error message informs you that the cartridge must be changed to an original. The printer is blocked except for the scan function. Indécoinçable! And as it consumes a lot of ink ... Note that you can print with the single black cartridge, color cartridge is mandatory and is consumed even in the dark ... Stay away.
