Smears on the front of coated paper
If a lot of ink is used on coated paper, the paper absorbs the ink quickly and expands. As the printheads move
over the paper, the printheads come into contact with the paper and smear the printed image.
Whenever you notice this problem, cancel the printing job immediately. Press the Cancel key on the front
panel and also cancel the job from your computer software. Otherwise the soaked paper might damage the
printheads.
Try the following suggestions to avoid this problem:
●
Use a recommended paper type. See
Supported paper types on page 27.
●
If the image you are printing contains intense color, try using HP Heavyweight Coated Paper.
●
Try to increase the margins by relocating the image within the page by using your software application.
●
If necessary, try changing to a non-paper-based material such as transparent film.
Smears or scratches on the front of glossy paper
Glossy paper can be extremely sensitive to the bin or to anything else that it contacts soon after printing.
This depends on the amount of ink that has been deposited on the paper and the environmental conditions at
the time of printing. Avoid any contact with the paper surface and handle the print with care.
Ink marks on the back of the paper
Ink residue on the platen or the input rollers is likely to mark the back of the paper. See Clean the platen
on page 138.
Defects near the top of a print
In a defect that affects only the start of a print, within 5.5 cm (2.2 in) of the leading edge of the paper, a band
of inconsistent color appears:
Use these steps to avoid this problem:
1. The easiest solution may be to increase the margins by relocating the image within the page in your
software application, so that the area of the paper affected by the problem (at the start of the page) will
be blank.
2. Align the printheads. See
Align the printheads on page 71.
3. Make sure that you are using appropriate print-quality settings. See
Select print quality on page 83.
