Clean the area around the ink nozzles

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.


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 control panel or the HP Image Zone. For more
information, see

Clean the print cartridges


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 touch the copper-colored contacts or ink nozzles. Touching

these parts can result in clogs, ink failure, and bad electrical connections.

To clean the area around the ink nozzles


Turn on the HP all-in-one and open the print-carriage access door.
The print carriage is on 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.
