Solution
  note:
The procedures below refer to a 'problem' cartridge. The 'problem' cartridge is identified either by a computer message or by the Start Copy lights.
  • If a computer message indicates a specific cartridge, that is the problem cartridge.
  • If there is no computer message, look at the Start Copy lights - if the Black Start Copy light is blinking, the cartridge on the right is the problem cartridge. If the Color Start Copy light is blinking, the cartridge on the left is the problem cartridge.
  • If both Start Copy lights are blinking and there is no computer message, perform the procedures below on both cartridges.
Work through the sections below in order. When the print cartridge light stops blinking, you have solved the problem.

The print cartridge may not have full electrical contact with the product. Removing and reinstalling the cartridge might help.
  note:
HP cannot guarantee the quality of remanufactured or refilled cartridges. Use genuine HP print cartridges to ensure good quality.
  1. Make sure the product is on. Press the Power button if it is not lit.
  2. Open the product cover, then wait until the print carriage is idle and silent.
  3. Press down lightly on the end of the problem cartridge to release it.

  4. Slide the cartridge out, and inspect it.
      caution:
    Do not touch the copper electrical contacts or the ink nozzles.

    2. Nozzles
    • Check the electrical contacts for debris. If any debris is evident, proceed to step two.
    • Make sure all the clear nozzle protective tape has been removed.
        caution:
      Do not attempt to remove the copper electrical strip.

    • Look at the number on the print cartridge label, and make sure it is compatible with the product. Compatible print cartridges are listed in the Printer Reference Guide supplied with the product.
  5. If the cartridge is compatible, reinstall it.
    • Cartridges marked with a triangle, go into the left carriage slot.
    • Cartridges marked with a square or pentagon, go into the right carriage slot.

  6. Close the product cover.
  7. Try to print again. If the issue persists, continue to the next step.
  1. Gather the following items to clean the ink cartridge and carriage:
    • Clean distilled water. Use bottled or filtered water if distilled water is not available. Tap water can contain contaminants that damage the ink cartridge.
    • Clean cotton swabs or any soft, lint-free material that will not stick to the ink cartridges (coffee filters work well).
    • Sheets of paper or a paper towel to rest the ink cartridge on during cleaning.
  2. Open the ink cartridge access door and wait until the carriage is idle and silent.
  3. Disconnect the power cord from the back of the printer.
  4. Remove the ink cartridge and place it on a piece of paper with the nozzle plate facing up.
      note:
    Do not leave the ink cartridges outside of the printer for more than 30 minutes. If the ink cartridge is outside of the printer for too long, the ink can dry and clog the nozzles.
  5. Dip a clean foam-rubber swab or lint-free cloth into distilled water, and then squeeze any excess water from it.
  6. Clean only the copper-colored contacts
    1. Copper-colored contacts
    2. Ink nozzles (do not clean)
  7. Repeat these steps for the other ink cartridge.
  8. Lightly moisten another cotton swab with distilled water, and then squeeze any excess water from the swab.
  9. Use the swab to clean the electrical contacts in the carriage, located inside the printer on the carriage slots.

  10. Wait 10 minutes to allow the ink cartridge and carriage electrical contacts to dry.
  11. Reinstall the ink cartridges.
  12. Close the ink cartridge access door.
  13. Reconnect the power cord to the back of the printer.
  14. Press the Power button to turn on the printer.
  15. Try to print a page.
  16. If you are still unable to print, repeat these steps to clean and reseat the ink cartridges. Multiple cleanings might be necessary to restore printing.

Step Three: Repeat reseating and cleaning steps
If the problem is not solved, repeat the reseating and cleaning procedures above.
If a cartridge replacement was not tried previously to solve this problem, replace the problem cartridge now. Go to Ink Cartridge and Printhead Limited Warrantyto see if the cartridge is covered under warranty.
