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.

Streaks Appear in All Scanned Images

If streaks appear in all your scanned images, try these solutions:
• Clean the scanner glass with a soft, dry, lint-free cloth or use a small amount of glass cleaner on the
cloth, if necessary. Paper towels are not recommended.
• Keep the document cover closed to prevent dirt or dust from getting inside.

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.
