Scanned Image Quality Problems
If you encounter quality problems with your scanned image, try these solutions:
Image is Distorted or Blurry
• Make sure your original is not wrinkled or warped. This may prevent the original from laying flat on the
scanner glass.

• Clean the scanner glass and the ADF and remove and dirt or dust on your originals.
• Do not press on the document cover or the original with too much force.
• Your product will not operate properly while tilted at an angle. Place your product on a flat, stable
surface that extends beyond its base in all directions.

• Make sure you select the correct Image Type for your original.

be set to None or Color Enhance.)
