Welcome to the HP Community

Manually clean the printhead

If the printhead cleaning tool did not resolve the problem, the printhead might be installed incorrectly, or there might be ink or debris on the printhead electrical contacts.

1. Gather the following materials:

   • A clean, lint-free cloth

   • A clean, dry cotton swab

   • Distilled or bottled water

        CAUTION: 

     Do not use tap water because it might contain contaminants that can damage the printhead.

2. Open the ink cartridge access door.

3. Press the tab on the front of the ink cartridge to release it, and then remove it.

   

4. Place the ink cartridges on a clean piece of paper with the ink opening face up.

      CAUTION: 

   Do not leave the ink cartridges outside the printer longer than 30 minutes. Doing so can result in damage to both the printer and the ink cartridges.

5. Lift the latch handle on the ink carriage until it stops.

   

6. Lift up to remove the printhead from the ink carriage.

   

7. Review the three areas of the printhead that need to be cleaned.

      CAUTION: 

   Do not touch the nozzles or the electrical contacts with your fingers. Touch the electrical contact areas only with the cleaning materials.

   1. Plastic ramp on the side of the ink nozzles

   2. Edge between nozzles and contacts

   3. Electrical contacts

8. Use a fresh, lightly dampened, lint-free cloth to wipe the electrical contact area from the bottom to the top until no new ink shows on the cloth. Use as many fresh, lightly dampened, lint-free cloths as necessary.

   

9. Use a fresh, lightly dampened, lint-free cloth to wipe any accumulated ink and debris from the edge between the nozzles and the contacts.

   

10. Use a fresh, lightly dampened, lint-free cloth to wipe the plastic ramps on both sides, away from the nozzles.

    

11. Wipe the previously cleaned areas dry with a dry, lint-free cloth.

12. Use a fresh, lightly dampened, lint-free cloth to wipe the electrical contact area inside the printer from bottom to the top until no new ink shows on the cloth. Use as many fresh, lightly dampened, lint-free cloths as necessary.

    

13. Wipe the electrical contact area dry with a dry, lint-free cloth.

14. Make sure the ink carriage latch handle is up, and then reinstall the printhead.

    

15. Carefully lower the ink carriage latch handle.

    

16. Reinsert the ink cartridges into the matching letter and colored dot slot, and then push the ink cartridge down and forward until it snaps into place.

    

    

17. Run your finger along the top of the ink cartridges to make sure none of them protrude. If any ink cartridges protrude and then press down firmly until each ink cartridge snaps into place.

18. Close the ink cartridge access door, and then Check the printer control panel display for the error message.
