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 device and open the print cartridge door.
The print carriage moves to the far right side of the device.
2. Wait until the print carriage is idle and silent, and then unplug the power cord from
the back of the device.
NOTE: Depending how long the HP All-in-One is unplugged, the date and
time might be erased. You might need to reset the date and time later, when
you plug the power cord back in.
3. Lightly press down on the print cartridge to release it, and then pull it toward you
out of the slot.
4. Inspect the print cartridge contacts for ink and debris buildup.
5. Dip a clean foam rubber swab or lint-free cloth into distilled water, and squeeze
any excess water from it.
6. Hold the print cartridge by its sides.
7. Clean only the copper-colored contacts. Allow the print cartridges to dry for
approximately ten minutes.
