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 65
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.

“Information on paper” on page 147
Cause: The print head needs to be cleaned.
Solution: Clean the print head, and then print a self-test report. Check the color
blocks in the report for any problems. If the color blocks show print quality problems,
perform a printer alignment.
