Solve copy problems
Prevent copy problems
The following are a few simple steps you can take to improve copy quality:
● Copy from the flatbed scanner. This will produce a higher quality copy than copying from the
automatic document feeder (ADF).
● Use quality originals.
● Load the media correctly. If the media is loaded incorrectly, it might skew, causing unclear images
and problems with the OCR program. See
Load paper and print media on page 81 for instructions.
● Use or make a carrier sheet to protect your originals.
Image problems
Problem Cause Solution
Images are missing or faded. The print cartridge might be defective. Replace the print cartridge. See Manage
supplies on page 170 .
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
darkness. If possible, find an original
document in better condition.
The original might have a colored
background. Touch Copy , and then touch Image
Adjustment. Adjust the Background
Cleanup slider to the right to decrease
the background.
Vertical white or faded stripes appear on
the copy. The media might not meet
HP specifications. Use media that meets HP specifications.
