Solution: Change the Paper Type setting to match the type of paper loaded in the input tray.

For more information, see:

•“Set the copy paper type” on page 123

•“Set the paper type for printing” on page 85

Cause: The copy or print paper type setting is incorrect.

Solution: Load high-quality paper in the input tray and print the image with a high print quality setting, such as Best, Maximum dpi, or High Resolution. Always make sure the paper you are printing on is flat. For best results when printing images, use HP Premium Plus Photo Paper.

If the problem persists, use the software you installed with the HP All-in-One or another software application to rotate your image 180 degrees so that the light blue, gray, or brown hues in your image do not print at the bottom of the page.

For more information, see:

“Information on paper” on page 171

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

Solution: Load paper with the side you want to print on facing down. For example, if you are loading glossy photo paper, load the paper with the glossy side down.

For more information, see: “Load paper” on page 76

Cause: The fax sender is using a low resolution or the original was poor quality.

Solution: Ask the sender to increase the resolution and to verify the quality of the original.

Printouts have vertical streaks

Cause: The paper type is not suitable for the HP All-in-One.

Solution: Use HP Premium Papers or any other paper type that is appropriate for the HP All-in-One.

Cause: The glass or automatic document feeder of the sending fax machine is dirty.

Solution: If you have vertical lines or streaks on the fax, the sender's fax machine might have dirt or dust on the glass or automatic document feeder. Check with the sender to see if the glass or automatic document feeder is clean.

Printouts are slanted or skewed

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