1. Check that the paper type you have loaded corresponds to the paper type selected in the front
panel and in your software. To check on the front panel, use the View information key .
2. Try changing to a thicker paper type, such as HP Heavyweight Coated Paper or HP Super
Heavyweight Plus Matte Paper.
3. Select a paper type that is slightly thinner than the paper you have loaded; this will persuade the
printer to use less ink. Here are some example paper types in ascending order of thickness: Plain
Paper, Coated Paper, Heavyweight Coated Paper, Super Heavyweight Plus Matte Paper.
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 basket 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 basket. Alternatively,
leave a sheet of paper in the basket so that freshly printed sheets do not make direct contact with
the basket.
Ink marks on the paper
If a lot of ink is used on plain or coated paper, the paper absorbs the ink quickly and expands. As the
printheads move over the paper, the printheads 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).
