3. Check that you are using appropriate print-quality settings (see Printing on page 64). In some cases,
you can overcome a print-quality problem merely by selecting a higher print-quality level. For instance,
if you have set the Print Quality slider to Speed, try setting it to Quality. If you change the print-quality
settings, you may wish to reprint your job at this point in case the problem has been solved.
4.

problem has been solved.

Go to the front panel and press , then , 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 158.

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 58.
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.
