Clean the print cartridge contacts
Clean the print cartridge contacts if you get repeated messages on your computer screen
prompting you to check a print cartridge after you already have cleaned or aligned the
print cartridges, or if the Check Print Cartridge light is blinking.
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.
TIP: Coffee filters are lint-free and work well for cleaning print cartridges.
• Distilled, filtered, or bottled water (tap water might contain contaminants that can
damage the print cartridges).
CAUTION: 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
1. Turn on the HP All-in-One and open the print cartridge door.
The print carriage moves to the far right side of the HP All-in-One.
2. Wait until the print carriage is idle and silent, and then unplug the power cord from
the back of the HP All-in-One.
