Clean the print cartridge contacts

Clean the print cartridge contacts only if you get repeated messages on the color graphics display prompting you to check a print cartridge after you already have cleaned or aligned the print cartridges.

Before cleaning the print cartridge contacts, remove the print cartridge and verify that nothing is covering the print cartridge contacts, then reinstall the print cartridge. If you continue to get messages to check the print cartridges, clean the print cartridge contacts.

Make sure you have the following materials available:

●Dry foam rubber swabs, lint-free cloth, or any soft material that will not come apart or leave fibers.

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

Warning Do not use platen cleaners or alcohol to clean the print cartridge contacts. These can damage the print cartridge or the HP all-in-one.

To clean the print cartridge contacts

1Turn on the HP all-in-one and open the print-carriage access door. The print carriage is on the far right side of the HP all-in-one.

2Wait until the print carriage is idle and silent, and then unplug the power cord from the back of the HP all-in-one.

Note When you unplug the power cord, the date and time are erased. You will need to reset the date and time later, when you plug the power cord back in. For more information, see Set the date and time. Any faxes stored in memory are also erased.

3Lift one of the latches to the open position, and then remove the print cartridge.

Note Do not remove both print cartridges at the same time. Remove and clean each print cartridge one at a time. Do not leave a print cartridge outside the HP all-in-one for more than 30 minutes.

4Inspect the print cartridge contacts for ink and debris buildup.

5Dip a clean foam rubber swab or lint-free cloth into distilled water, and squeeze any excess water from it.

6Hold the print cartridge by its sides.

7Clean only the copper-colored contacts. For information on cleaning the ink nozzle area, see Clean the area around the ink nozzles.
