My printer persists in saying that I need new cartridges -- even though I just replaced them last week.  I've run the cartridge-cleaning utility, but problem persists.  When I installed the cartridges, the printer confirmed that they were office HP cartridges.  (I bought them from Staples.)

@10E_Baker,

 

Thanks for reaching out to the HP Support community!

  • What are the ink levels on the ink cartridges?

Let's try these steps:

 

Step 1: Check the ink levels

  • On the printer control panel, touch the ink level icon
  • Check the ink levels.
  • If the ink levels are fine, proceed to the next step. If depleted replace the cartridge.

Step 2: Power Reset

  • Make sure this printer is plugged into a direct wall, not a surge protector.
  • Turn the printer on.
  • Wait until the printer is idle and silent before you continue.
  • Remove all of your ink cartridges from the printer and close the door.
  • With the printer turned on, disconnect the power cord from the rear of the printer.
  • Unplug the power cord from the wall outlet.
  • Wait at least 60 seconds.
  • Plug the power cord back into the wall outlet.
  • Reconnect the power cord to the rear of the printer.
  • Turn on the printer, if it does not automatically turn on. The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
  • Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
  • Reinsert the ink cartridges, and then close the ink cartridge access door.
  • Try to print/copy
  • If the issue persists, proceed to the next level

Step 3: Remove and clean the ink cartridges.

 

  • Gather the following materials:
    • Dry foam rubber swabs, lint-free cloth, or any soft material that does not come apart or leave fibers (coffee filters work well)

    • Distilled, filtered, or bottled water (tap water might contain contaminants that can damage the cartridges)

  • press the Power button to turn on the printer, if it is not already on.

  • Open the cartridge access door

  • The cartridges would move to the middle

  • Disconnect the power cord from the rear of the printer.

  • Remove the ink cartridges

  • Hold the cartridge by its sides.

         

  • Lightly moisten a foam-rubber swab or lint-free cloth with distilled water, and then squeeze any excess water from it.

  • Clean only the copper-colored contacts on the cartridge, and then allow the cartridge to dry for about 10 minutes.

              

  1. Copper-colored contacts

  2. Ink nozzles (do not clean)

  • Lightly moisten another foam-rubber swab or lint-free cloth with distilled water, and then squeeze any excess water from it.

  • Use the swab or cloth to clean the electrical contacts in the cartridge slots, located inside the carriage in the printer.

           

  • Allow the carriage contacts to dry for about 10 minutes.

  • Reinsert the cartridges

  • Close the cartridge access door

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

  • Power on the printer.

  • Try to print/copy
