Scanned Image Quality Problems
If you encounter quality problems with your scanned image, try these solutions:
Image is Distorted or Blurry
• Do not move your original or your product during scanning.
• If you are scanning from the ADF, place your originals on the scanner glass. Some originals may not
be scanned properly from the ADF.
• 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 or Epson ScanSmart settings (if available) and try scanning again:
• Increase the
Resolution

Scanned Image Colors Do Not Match Original Colors
Printed colors can never exactly match the colors on your computer monitor because printers and
monitors use different color systems: monitors use RGB (red, green, and blue) and printers typically use
CMYK (cyan, magenta, yellow, and black).
Check the color matching and color management capabilities of your computer, display adapter, and the
software you are using to see if they are affecting the palette of colors you see on your screen.
