If the HP All-in-One is used in a dusty environment, a small amount of debris might
accumulate inside the device. This debris can include dust, hair, carpet, or clothing fibers.
When debris gets on the print cartridges, it can cause ink streaks and smudges on printed
pages. Ink streaking can be corrected by cleaning around the ink nozzles as described
here.
NOTE:
Clean the area around the ink nozzles only if you continue to see streaks
and smudges on your printed pages after you have already cleaned the print
cartridges by using the software you installed with the HP All-in-One.
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 touch the copper-colored contacts or ink nozzles. Touching
these parts can result in clogs, ink failure, and bad electrical connections.
