Thin vertical lines across the image

Sensitive-paper mode

The whole image is blurry or grainy
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 42.
2. Check that you are printing on the correct side of the paper.
3. Check that you are using appropriate print-quality settings (see
Printing on page 50). 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.

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.
