Improve copy and scan image quality
If the product is having image quality problems, try the following solutions in the order presented to resolve
the issue.
● Check the scanner glass for dirt and smudges
● Check the paper settings
● Check the image adjustment settings
● Optimize for text or pictures
● Check the scanner resolution and color settings on the computer
● Edge-to-edge copying
Try these few simple steps first:
● Use the flatbed scanner rather than the document feeder.
● Use high-quality originals.
● When using the document feeder, load the original document into the feeder correctly, using the paper
guides, to avoid unclear or skewed images.
If the problem still exists, try these additional solutions. If they do not fix the problem, see “Improve print
quality” for further solutions.
