- Hewlett-Packard Printer User Manual

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 prevents the photo paper from curling.

Cause: The wrong kind of paper was loaded in the input tray.
If this did not solve the issue, try the next solution.
Solution 2: Use a higher print quality setting
Solution: Check the print quality setting and make sure it is not set too low.
Print the image with a high print quality setting, such as Best or Maximum dpi.
Cause: The print quality setting was set too low.
If this did not solve the issue, try the next solution.
Solution 3: Rotate the image
Solution: If the problem persists, use the HP software or another software
application to rotate your image 180 degrees so that the light blue, gray, or brown
hues in your image do not print at the bottom of the page.
Cause: The defect is more noticeable in areas of uniform light colors, so rotating
the image may help.
Printouts have horizontal streaks or lines
Horizontal streaks are streaks that are at right angles (or perpendicular) to the direction
that the paper moved through the printer.
Try the following solutions if your printout has lines, streaks, or marks on it that run
