HP Photosmart C4344 All-in-One Printer - Manual (Page 105)

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 product.
To clean the print cartridge contacts
1. Make sure the product is turned on.
CAUTION: If the product is turned off when you open the print cartridge door to
access the print cartridges, it will not release the cartridges for changing. You
might damage the product if the print cartridges are not docked safely when you
try to remove them.
2. Open the print cartridge door.
The print carriage moves to the far right side of the product.
3. Wait until the print carriage is idle and silent, and then unplug the power cord from
the back of the product.
4. Lightly press down on the print cartridge to release it, and then pull it towards you out
of the slot.
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 product
for more than 30 minutes.
5. Inspect the print cartridge contacts for ink and debris buildup.
6. Dip a clean foam rubber swab or lint-free cloth into distilled water, and squeeze any
excess water from it.
7. Hold the print cartridge by its sides.
