Clean the area around the ink nozzles

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.


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).


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 for more than 72 hours, 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.


Lift one of the latches to the open position, and then remove the print cartridge.


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 HP All-in-One for more than 30 minutes.


Place the print cartridge on a piece of paper with the ink nozzles facing up.


Lightly moisten a clean foam rubber swab with distilled water.


Clean the face and edges around the ink nozzle area with the swab, as shown
