Hi @pjmacd19,

 

I'd like to help!

 

I understand you are receving a printhead error with the new printhead

 

Try the below suggestions -

 

Replacing the printhead

 

Replace the printhead to resolve print quality problems that do not go away after replacing ink cartridges.

  1. With the printer on, open the ink cartridge access door, and then wait until the carriage stops.

  2. Remove each ink cartridge by pressing the front tab, and then lifting the cartridge.

  3. Lift the carriage latch handle to unlock the printhead.

  4. Grasp the sides of the printhead, and then lift up to remove it.

    NOTE: 

    To avoid ink stains, do not touch the bottom of the printhead.

  5. Place the printhead on a sheet of paper, and then set aside.

  6. Using the pre-moistened wipes that came with the replacement printhead, clean the electrical contacts inside the carriage from top to bottom, wiping in the down direction only.

    CAUTION: 

    Do not wipe up or side to side. This can damage the electrical contacts.

  7. Remove the replacement printhead from the packaging.

    CAUTION: 

    Do not touch the electrical contacts or nozzles to avoid damaging them.

  8. With the electrical contacts facing the rear of the printer, insert the printhead into the carriage.

  9. Close the carriage latch.

  10. Install the new cartridges that came with the replacement printhead, and then close the ink cartridge access door.

    CAUTION: 

    Do not reuse the ink cartridges from the previous printhead. Old cartridges can damage the new printhead.

  11. If prompted to align the cartridges, select OK on the printer control panel.

    The printhead is installed, and the printer is ready for printing.

If the issue persists, I'd suggest you Contact HP in your region regarding the service options for your printer

 

Hope this helps! Keep me posted.
