6.7 Storing and handling photo paper
Follow these instructions to maintain the quality of your HP brand photo paper.
Storage
• Keep unused photo paper in a resealable plastic bag, in the box in which it was
originally packaged. Store the packaged photo paper on a flat surface in a cool
place.
• When you are ready to print, remove only the paper that you plan to use
immediately from the plastic bag. When you have finished printing, return any
unused photo paper to the plastic bag.
• Do not leave unused photo paper in the printer paper tray. The paper might
start to curl, which can reduce the quality of your photographs.
Handling
• Always hold photo paper by its edges. Fingerprints on photo paper can reduce
print quality.
• Verify that the photo paper is not curled. If the photo paper is curled, place the
paper in a plastic bag and gently bend it the opposite direction of the curl until
the paper lies flat. If the problem persists, use photo paper that is not curled.
