NOTE: If cleaning the printhead does not solve this print quality issue, contact

HP support for service.

If you do not see any defects on the print quality report, then the printing system is working

correctly. There is no reason to replace supplies or have the product serviced, because

they are functioning properly. If you still have a print quality problem, here are some other

things you can check:

• Check the paper.

• Check the print settings.

• Make sure your image has sufficient resolution.

• If the problem seems confined to a band near the edge of your printout, use the

software you installed with the product or another software application to rotate the

image 180 degrees. The problem might not appear on the other end of the print.
