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 settings (if available) and try scanning again:
• Select the Descreening setting on the Advanced Settings tab.
• Select a lower Resolution setting.
• Place the original at a slightly different angle.
