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.
