Troubleshooting

Chapter 13

Cause: You are printing on the wrong side of the paper.

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.

Printouts are slanted or skewed

Cause: The paper is not feeding properly or is loaded incorrectly.

Solution: Make sure the paper is loaded correctly.

For more information, see:

“Load full-size paper” on page 35

Cause: More than one type of paper is loaded in the input tray.

Solution: Load only one type of paper at a time.

Cause: The rear door might not be securely installed.

Solution: Make sure the rear door is securely installed.

Paper is not picked up from the input tray

Cause: There is not enough paper in the input tray.

Solution: If the HP All-in-One is out of paper or there are only a few sheets remaining, load more paper in the input tray. If there is paper in the input tray, remove the paper, tap the stack of paper against a flat surface, and reload the paper into the input tray. To continue your print job, press Start Copy Black on the control panel of the HP All-in-One.
