When I choose to print any type of document from my computer (MacBook), the BLACK COLOUR does not work. The page will come out from the printer with all the colors on it but NOT the black one. The system is not indicating me any error (the black cartridge seems allocated in its place). No errors but the black color is not working at all.

Please help me I'm desperate

Hi @AriBochicchio

Welcome to the HP Support Community. I'd be happy to assist you. Let us try these steps to resolve this issue:

  • Make sure you are using HP ink cartridges.
  • Try making a standalone copy in black and check if that works. By this, we can conclude if this is a hardware or a driver issue. you may remove the color ink cartridge from the printer. This printer supports printing in single-cartridge mode.

Reset the printer

  1. With the printer turned on, disconnect the power cord from the rear of the printer.
  2. Wait at least 60 seconds.
  3. Reconnect the power cord to the rear of the printer.
  4. Turn ON the printer, if it does not automatically turn on.
  5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.
