Improve copy and scan image quality
Introduction
If the printer 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
● Eliminate lines or streaks when using the document feeder
● 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
● Clean the pickup rollers and separation pad in the document feeder (fw models only)
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.
Check the scanner glass for dirt and smudges
Over time, specks of debris might collect on the scanner glass and white plastic backing, which can affect
performance. Use the following procedure to clean the scanner.
1. Press the power button to turn the printer off, and then disconnect the power cable from the electrical
outlet.
2. Open the scanner lid.
3. Clean the scanner glass and the white plastic backing underneath the scanner lid with a soft cloth or
sponge that has been moistened with nonabrasive glass cleaner.
CAUTION: Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon tetrachloride on
any part of the printer; these can damage the printer. Do not place liquids directly on the glass or platen.
They might seep and damage the printer.
4. Dry the glass and white plastic parts with a chamois or a cellulose sponge to prevent spotting.
5. Connect the power cable to an outlet, and then press the power button to turn the printer on.
