Hi @AM231986


Welcome to the HP Support Community. I'd be happy to assist you with the  "Problem with printhead"


Let's try a power reset on the printer


Reset the product

  • With the printer turned on, disconnect the power cord from the rear of the printer.
  • Unplug the power cord from the wall outlet.
  • Wait at least 60 seconds.
  • Plug the power cord back into the wall outlet.
  • Reconnect the power cord to the printer.
  • Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

The printer might display an error if the printheads are not correctly installed.


Perform the following steps for the printhead(s) indicated by the Printhead icons  on the printer control panel.

  1. Close the output tray extender, and then rotate the output tray left to stow it in the printer.

  2. Open the exterior door, and then open the printhead access door.

  3. If the carriage is not visible, press and hold the Black Color Copy button for 3 seconds.

    The carriage moves to the center of the printer.

    Access the print carriage

  4. Gently push down on the blue carriage latch.

    The blue carriage latch opens.

    Open the printhead carriage latch

  5. Lightly press down on the printhead to release it, and then pull the printhead out of its slot.

    Removing the printheads

  6. Make sure the plugs on top of the printhead have been removed.

    Pull the orange plugs

  7. Make sure the tape from the printhead contacts has been removed.


    Do not touch the copper-colored contacts or the ink nozzles. Do not replace the protective tape on the contacts. Handling these parts can result in clogs, ink failure, and bad electrical connections.

    Remove the tape

  8. Slide the printhead at a slight upward angle into the empty slot, and then gently push up on the printhead until it snaps into place.

    Insert the printheads

    • Insert the tri-color printhead into the left slot.

    • Insert the black printhead into the right slot.

  9. Close the blue carriage latch by pushing down firmly until the latch snaps into place.

  10. Close the printhead access door.

  11. Close the exterior door.

    The priming process continues.

Hope this helps! Keep me posted.
