Clean the ink cartridge contacts

Clean the copper-colored ink cartridge contacts if all ink cartridges are installed and a message appears on the display that says a cartridge is missing or damaged.

Before cleaning the ink cartridge contacts, remove the ink cartridge and verify that nothing is covering the ink cartridge contacts or the ink cartridge slot, then reinstall the ink cartridge. If you continue to get a message that says a cartridge is missing or damaged, clean the ink cartridge contacts. If you still get this message after cleaning the contacts, you will need a replacement ink cartridge. Remove the affected ink cartridge and look at the end-of-warranty date on the bottom. If it is before the end-of-warranty date, contact HP support to obtain a replacement ink cartridge.

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 ink cartridges).

CAUTION: Do not use platen cleaners or alcohol to clean the ink cartridge contacts. These can damage the ink cartridge or the HP All-in-One.
