The print is scuffed or scratched
The black ink pigment can be scuffed or scratched when touched by a finger, a pen or some other object. This is
particularly noticeable on coated paper.
Glossy paper may be extremely sensitive to the bin or to anything else that it contacts soon after printing,
depending on the amount of ink used and the environmental conditions at the time of printing.
To reduce the risk of scuffs and scratches:
Handle prints carefully.
Avoid stacking prints on top of each other.
Catch your prints as they are cut from the roll and do not let them fall into the bin. Alternatively, leave a
sheet of paper in the bin so that freshly printed sheets do not make direct contact with the bin.
Increase the drying time. At the front panel, swipe down the dashboard, touch

Ink marks on the paper
This problem can occur for several different reasons.
Horizontal smears on the front of coated paper
If a lot of ink is used on plain or coated paper, the paper absorbs the ink quickly and expands. As the printhead
moves over the paper, the printhead may come into contact with the paper and smear the printed image. This
problem is normally seen only on cut sheets of paper (not on roll paper).
Whenever you notice this problem, cancel the printing job immediately. Touch
and also cancel the job from
your computer application. Soaked paper can damage the printhead.
If you notice poor print quality after this has happened, clean the printhead. See
Clean the printhead
on page
100
.
Try the following suggestions to avoid this problem:
1.
Check that the paper type you have loaded corresponds to the paper type selected in the front panel and in
your software. See
View information about the paper
on page
39
.
2.
Use a recommended paper type (see
Order paper
on page
114
) and the correct print settings.
3.
If using sheet paper, try rotating the sheet 90 degrees. The orientation of the paper fibers may affect
performance.
