If there is ink remaining in the print cartridges, but you are still noticing a problem,
print a self-test report to determine if there is a problem with the print cartridges. If the
self-test report shows a problem, clean the print cartridges. If the problem persists,
you might need to replace the print cartridges.

Cause: The print quality setting on the HP All-in-One is set too low.
Solution: Check the quality setting. Use a higher quality setting to increase the
amount of ink used for printing.
Cause: The paper type is not suitable for the HP All-in-One.
Solution: If the paper you are using is too fibrous, the ink applied by the HP All-in-
One might not fully cover the surface of the paper. Use HP Premium Papers or any
other paper type that is appropriate for the HP All-in-One.
For more information, see:
“Choose papers for printing and copying” on page 32
Cause: The paper type setting is incorrect.
Solution: Change the paper type setting to match the type of paper loaded in the
input tray. The HP All-in-One automatically detects the paper type for plain and photo
