Check the printheads

Print the print quality diagnostic page on a clean sheet of white paper. Evaluate any problem areas, and perform the recommended actions. For more information, see To print the print quality diagnostic page.

The printout has a horizontal band of distortion near the bottom of a borderless print

Check the paper type

HP recommends that you use HP papers or any other paper type that is appropriate for the product. Always make sure the paper you are printing on is flat. Uncurl paper by bending it in the opposite direction of the curl. For best results when printing images, use HP Advanced Photo Paper. Store photo media in its original packaging inside a resealable plastic bag on a flat surface, in a cool place. When you are ready to print, remove only the paper you plan to use immediately. When you have finished printing, return any unused photo paper to the original package, and reseal the bag. This will prevent the photo paper from curling. For more information, see Select print media.

Use a higher print quality setting

Check the print quality setting and make sure it is not set too low. Print the image with a high print-quality setting, such as Best or Maximum dpi.

Rotate the image

If the problem persists, use the software you installed with the product 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. The defect is more noticible in areas of uniform light colors, so rotating the image may help.

Clean the printhead

Manually clean the printhead. For more information, see To clean the printhead contacts manually.

Colors do not line up properly

Check the graphics placement
