Problem Cause Solution
Images are missing or faded. The print cartridge might be defective or
low. Replace the print cartridge.
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 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 paper might not meet HP specifications. Use paper that meets HP specifications.
The print cartridge might be defective or
low. Replace the print cartridge.
Unwanted lines appear on the
copy.
