• Make sure you select the correct Image Type for your original.
• Select the Advanced Settings tab and adjust the Brightness setting.

Color or Grayscale, change the Text Enhancement setting to High.

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.
To adjust the colors in your scanned image, adjust these Epson Scan 2 or Epson ScanSmart settings (if
available) and try scanning again:
• Make sure you select the correct Image Type for your original.
• If the Image Type setting is Color or Grayscale, adjust the Contrast setting.
• If the Image Type setting is Black & White or Grayscale, adjust the Color Enhance setting.
