Welcome to the HP support community.

 

Clean the printhead

  1. Open the door to access to the cartridges.

  2. Wait until the carriage stops moving before you continue.

  3. Push the tab on a cartridge, and then pull the cartridge from its slot. Perform these steps for all the cartridges.

       CAUTION: 

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

  4. Lift the latch handle on the carriage until it stops.

  5. Lightly dampen a clean, lint-free cloth with bottled or distilled water.

  6. Use the damp cloth to wipe the electrical contacts from the bottom to the top. Do not go past the edge between the electrical contacts and the ink nozzles. Repeat this motion until no ink appears on the cloth.

    Clean the electrical contacts

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

  9. Dry the previously cleaned areas with a clean, dry, lint-free cloth.

  10. Use a new, lightly dampened, lint-free cloth to wipe the electrical contacts inside the printer by wiping them from top to bottom. Repeat this motion until no ink appears on the cloth.
