Solution: Load paper with the print side down. For example, if you are loading
glossy photo paper, load the paper with the glossy side down.
Printouts have vertical streaks
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.
