Clean the print cartridge contacts

Clean the print cartridge contacts only if you get repeated messages on the control
panel 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
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).


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


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


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


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.
