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 printer.
Always make sure the paper you are printing on is flat. For best results when printing
images, use HP Advanced Photo Paper.
Store specialty 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 prevents the photo paper from curling.
