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.
