Solution 2: 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. Print quality troubleshooting 109
