Welcome to the HP support community.


Update the printer firmware

Updating the printer firmware might resolve printhead problems. Go to Updating or Upgrading Printer Firmware for more information.


Reseat the printhead up to three times

  1. With the printer turned on, unplug the power cord from the rear of the printer.

  2. Lift the carriage latch, slightly lift the printhead, lower the printhead back into the carriage, wiggle the printhead left and right, and then lower the carriage latch to lock the printhead into place.

  3. Close the cartridge access door.

  4. Reconnect the power cord to the rear of the printer.

  5. Wait for the printer to start, and then look for the error.

    • If the error message persists, repeat the steps to reseat the printhead up to three times.
