Ripple Patterns Appear in an Image
You may see a ripple pattern (called a moiré) in scanned images of printed documents. This is caused
by interference from differing pitches in the scanner's screen and your original's halftone screen. To
reduce this effect, adjust these Epson Scan 2 settings (if available) and try scanning again:
• Select the Descreening setting.
• Select a lower Resolution setting.

Image is Scanned Upside-Down
Your product scans using the Auto Photo Orientation setting. This setting checks the preview image
for faces, the sky, and other features, and then correctly rotates the photo when it is scanned, if
necessary.
If your photo is not oriented correctly using this option, you can turn Auto Photo Orientation off and
scan again. When Photo Mode is selected, select Thumbnail Options from the Main Settings tab.
Select On or Off and scan your document again.
Note: Auto Photo Orientation will not work when you scan newspapers, magazines, documents,
illustrations, or line art, or images smaller than 2 inches (5.1 cm) on any side.

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).
