NOTE: During ink-backup mode, the product can only print jobs from the
computer. You cannot initiate a print job from the control panel (such as printing
a photo from a memory card).
Check to see if your print cartridge is still under warranty and end of warranty date
has not been reached.
• If the end of warranty date has been reached, purchase a new print cartridge.
• If the end of warranty date has not been reached, contact HP support. Go to
www.hp.com/support . If prompted, choose your country/region, and then click
Contact HP for information on calling for technical support.
Cause: The print cartridge was damaged.
The printout has a horizontal band of distortion near the bottom of a borderless
print
Try the following solutions if your borderless print has a blurry band or line on the bottom
of it.
• Solution 1: Check the paper type
• Solution 2: Use a higher print quality setting
• Solution 3: Rotate the image
Solution 1: 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.
For more information, see:
• “Recommended papers for printing” on page 8
• “Information on paper” on page 12
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 quality setting. Use a higher quality setting to increase the
amount of ink used for printing.
