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 HP All-in-One and open the print cartridge door. The print carriage moves to the far right side of the HP All-in-One. 2. Wait until the print carriage is idle and silent, and then unplug the power cord from the back of the HP All-in-One. 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 HP Allin-One 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. 6. Clean the face and edges around the ink nozzle area with the swab, as shown below. 1 Nozzle plate (do not clean) 2 Face and edges around the ink nozzle area CAUTION: Do not clean the nozzle plate. 7.
