Line of Dots Appears in All Scanned Images
If a line of dots appears in all your scanned images, clean the scanner glass with a soft, dry, lint-free
cloth or use a small amount of glass cleaner on the cloth, if necessary. Paper towels are not
recommended.
Caution:
Do not spray glass cleaner directly on the scanner glass.

Placing Originals on the Product
Image is Distorted or Blurry
If a scanned image appears distorted or blurry, try these solutions:
• Make sure your original is not wrinkled or warped. This may prevent the original from laying flat on the
scanner glass.
• Do not move your original or your product during scanning.
• Your product will not operate properly while tilted at an angle. Place it on a flat, stable surface that
extends beyond the base of the product in all directions.
• Adjust these Epson Scan settings (if available) and try scanning again:
• Select the
Unsharp Mask
setting.
• Adjust the
Auto Exposure
setting.
• Increase the
Resolution
setting.
