Cause: There might be fiber or dust built up around the ink nozzle area on the print
cartridges.
Solution: Check the print cartridges. If it looks as though there are fibers or dust
around the ink nozzles, clean the ink nozzle area of the print cartridge.
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 All-in-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. Slide the print cartridge back into the slot. Push the print cartridge forward until it
clicks into place.
