Straight Lines in an Image Appear Crooked
If straight lines in an original appear crooked in a scanned image, make sure to place your original
straight when you scan it.
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.
Keep the document cover closed to prevent dirt or dust from getting inside.

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.
• 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:
• Make sure you select the correct Image Type for your original.
• Increase the Resolution setting.
• If the Image Type setting is Black & White , adjust the Threshold setting. (The Image Option must
be set to None or Color Enhance .)
• 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 .
Image is Too Dark
• Make sure you select the correct Image Type for your original.
• If the Image Type is set to Auto , Color or Grayscale , adjust the Brightness setting.
• Check the brightness and contrast settings of your computer monitor.
