Go to the front panel and press , then Image-quality maintenance > Calibration status to see
the paper advance calibration status. If the status is DEFAULT, you should perform paper advance
calibration: see Recalibrate the paper advance on page 180.
If the problem persists despite all the above actions, contact your customer service representative for
further support.
The paper is not flat
If the paper does not lie flat when it comes out of the printer, but has shallow waves in it, you are likely to see
defects in the printed image, such as vertical stripes. This can happen when you use thin paper that becomes
saturated with ink.
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 60.
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.
4. If you see horizontal stripes, try printing the same job rotated; this sometimes reduces the visibility of
the stripes.
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.
Photo 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.
●
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.
