Print quality troubleshooting

If you are having problems with print quality, try the solutions in this section and observe the following guidelines.

To troubleshoot print quality issues

1.Check the print cartridges.

HP recommends that you use genuine HP print cartridges. Genuine HP print 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 supplies. Printer service or repairs required as a result of using a non-HP supply will not be covered under warranty.

If you believe you purchased genuine HP ink cartridges, go to:

For more information, see Replace the print cartridges.

2.Check the ink levels.

If you have installed a refilled or remanufactured print cartridge, or a cartridge that has been used in another printer, the ink level indicator will be inaccurate or unavailable. The ink levels provided are an estimate. When print cartridges are truly low on ink, printouts will be faded or streaked. As long as print quality is acceptable, there is no reason to replace print cartridges. Low ink warnings are provided for planning purposes only.

For more information, see Check the estimated ink levels.
