10.Gently close the print cartridge door and plug the power cord into the back of the device.

Clean the area around the ink nozzles

If the device 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 device control panel or 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.

To clean the area around the ink nozzles

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.

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 device for more than 30 minutes.

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

5.Lightly moisten a clean foam rubber swab with distilled water.
