Image problems
Problem Cause Solution
Images are missing or faded. The print-cartridge might be defective or
empty. Replace the print cartridge. See Print
cartridge on page 131 .
The original might be of poor quality. If your original is too light or damaged, the
copy might not be able to compensate, even
if you adjust the contrast. If possible, find an
original document in better condition.
The contrast settings might be set
incorrectly. Use the control-panel Lighter/Darker button
to change the contrast setting.
The original might have a colored
background. Colored backgrounds might cause images in
the foreground to blend into the background,
or the background might appear in a
different shade. If possible, use an original
document without a colored background.
Vertical white or faded stripes
appear on the copy. The media might not meet
HP specifications. Use media that meets HP specifications.
