Troubleshooting 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 print cartridges, go to: www.hp.com/go/anticounterfeit Cause: Non-HP ink was being used. If this did not solve the issue, try the next solution. Solution 2: Check the print settings Solution: Check the print settings. • Check the paper type setting to make sure it matches the type of paper loaded in the input tray. • Check the quality setting. Use a higher quality setting to increase the amount of ink used for printing. For more information, see: • Set the paper type for printing • Change the print speed or quality • Print using Maximum dpi • Make a Fast copy Cause: The paper type or print quality settings were incorrectly. If this did not solve the issue, try the next solution. Solution 3: Check the paper type Solution: HP recommends that you use HP Advanced Papers or any other paper type that is appropriate for the product. Always make sure the paper you are printing on is flat. 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, dry 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 plastic bag. This will prevent the photo paper from curling. NOTE: There is no problem with the ink supplies and replacing the print cartridges is unnecessary. For more information, see: • Recommended papers for printing and copying • Information on paper Cause: The wrong kind of paper was loaded in the input tray. Print quality troubleshooting 105
