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:
Cause: Non-HP print cartridges were being used.
Step 2: Check the ink levels
Solution: Check the estimated ink levels in the cartridges.
NOTE:
Ink level warnings and indicators provide estimates for planning
purposes only. When you receive a low-ink warning message, consider having a
replacement cartridge available to avoid possible printing delays. You do not need
to replace the cartridges until print quality becomes unacceptable.
For more information, see:
“Check the estimated ink levels” on page 47
Cause: The print cartridges might have insufficient ink.
Check paper
Follow these steps.
•
Step 1: Use the correct paper type
•
Step 2: Load the stack of paper correctly
Step 1: Use the correct paper type
Solution: HP recommends that you use HP papers or any other paper type that is
appropriate for the product. Make sure only one type of paper is loaded at a time.
Always make sure the paper you are printing on is flat. For best results when printing
images, use HP Advanced Photo Paper.
Cause: The paper type was incorrect or more than one type of paper was loaded.
Step 2: Load the stack of paper correctly
Solution: Remove the stack of paper from the paper tray, reload the paper, and
then slide the paper-width guide inward until it stops at the edge of the paper.
NOTE:
Do not leave unused photo paper in the paper tray. The paper might start
to curl, which could reduce the quality of your printout. For best results, do not
allow printed photos to stack up in the paper tray.
