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.
If you are scanning from the ADF, try cleaning the ADF and scan again.

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 your product on a flat, stable
surface that extends beyond its base in all directions.
Adjust these Epson Scan 2 settings (if available) and try scanning again:
Increase the Resolution setting.
If the Image Type setting is Black & White, adjust the Threshold setting.
If the Image Type setting is Color or Grayscale, select the Unsharp Mask setting.
If the Image Type setting is Black & White, select Text Enhancement. If the Image Type setting is
Color or Grayscale, change the Text Enhancement setting to High.
