Welcome to the HP support community.

Clean the electrical contacts

1. Turn the printer on.

2. Open the door to access the cartridges.

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

4. Remove the cartridge indicated in the error message from its slot, holding it by its side.

      CAUTION: 

   Do not touch the copper-colored contacts or the ink nozzles. Touching these parts can result in clogs, ink failure, and bad electrical connections.

5. Remove any protective tape that still might be on the contacts.

      CAUTION: 

   Do not touch or try to remove the copper electrical strip.

   

6. Lightly dampen a lint-free cloth with distilled water, and then clean only the copper-colored contacts on the cartridge.

   

7. Lightly dampen a lint-free cloth with distilled water, and then clean the electrical contacts in the carriage, located inside the printer.
