Image Colors are Patchy at the Edges

If you are scanning a thick or warped original, cover its edges with paper to block external light as you
scan it.

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.

Scanned Image Edges are Cropped

If the edges of a scanned image are cropped, make sure your original is placed correctly for scanning. If
necessary, move your original away from the edges of the scanner glass slightly.
In the Epson Scan 2 or Epson ScanSmart settings, set the Edge Fill setting to None.
