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 on the Advanced tab.
• Select a lower Resolution setting.

Spots or Lines Appear in All Scanned Images
If spots or lines appear in all your scanned images, try these solutions:
• Make sure the surface of your original is clean.
• Make sure there is no debris or dirt inside the ADF.
• Disconnect any connected cables and clean inside the scanner.
• Enable the Detect Glass Dirt setting on the control panel. (Press the home button, select Settings
> Scanner Settings > Detect Glass Dirt , and select On-Low , if the alert displays a misdetection, or
On- High if dirt is not detected.) When an alert displays on the control panel, clean the glass scanning
surfaces inside your scanner using a genuine Epson cleaning kit or a soft, moist cloth.
Note: If there are scratches on the glass surface, the alert screen may continue to appear even after
cleaning the glass. Contact Epson for information about replacing the glass.
• Avoid scanning in direct sunlight.
