Solution 3: Check the paper loaded in the input tray
Solution: Make sure the paper is loaded correctly and that it is not wrinkled or
too thick.
•
Load paper with the print side facing down. For example, if you are loading
glossy photo paper, load the paper with the glossy side down.
• Make sure the paper lays flat in the input tray and is not wrinkled. If the
paper is too close to the printhead during printing, the ink might be
smeared. This can happen if the paper is raised, wrinkled, or very thick,
such as a mailing envelope.
For more information, see:
Load paper.
Cause: The paper was loaded incorrectly, or it was wrinkled or too thick.

Solution 4: Check the paper type
Solution: HP recommends that you use HP papers or any other paper type
with ColorLok technology that is appropriate for the printer. All papers with the
ColorLok logo are independently tested to meet high standards of reliability and
print quality, and produce documents with crisp, vivid color, bolder blacks and dry
faster than ordinary plain papers.
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.
NOTE: For this issue, there is not a problem with your ink supplies.
Therefore, replacing the ink cartridges is not necessary.
