If this did not solve the issue, try the next solution.
Solution 2: Check the paper type
Solution: HP recommends that you use HP 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.
