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 36

Cause: You are using non-HP ink.

Solution: HP recommends that you use genuine HP ink cartridges. Genuine HP ink cartridges are designed and tested with HP printers to help you easily produce great results, time after time.

NOTE: HP cannot guarantee the quality or reliability of non-HP ink. Printer service or repairs required as a result of printer failure or damage attributable to the use of non-HP ink will not be covered under warranty.

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.

If the problem persists after cleaning and aligning, contact HP support for help. Go to:

Troubleshooting

Cause: The print quality setting on the HP All-in-One is set too low.

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.
