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, select Settings > Scanner Settings > Scan Settings in Epson ScanSmart and try
adjusting these settings and scanning again:
• On the Main Settings tab, try decreasing the Resolution setting.
• On the Advanced Settings tab, select the Descreening setting.

Uneven Colors Appear in Scanned Image

If the scanner is subjected to strong light such as direct sunlight, the internal sensor misdetects the light
and colors in the scanned image become uneven.
• Change the orientation of the scanner so that strong light is not falling on the front of the scanner.
• Move the scanner to a location where it will not be subjected to strong light.

Spots or Lines Appear in All Scanned Images

If spots or lines appear in all your scanned images, try the following solutions:
• Clean the rollers and glass scanning surfaces inside your product using a genuine Epson cleaning kit
or a soft, moist cloth.
• Remove any dirt from your original.
• Enable the Detect Glass Dirt setting in the Epson Scan 2 Utility. You can also enable Glass Dirt
Detection on the product's control panel (Settings > Scanner Settings > Glass Dirt Detection > On-
Low or On-High).
Note: If glass dirt detection does not work correctly, adjust the setting. If the glass dirt alert screen
appears after cleaning the inside of the product, check the glass surface again (scratches on the glass
may be detected as a glass dirt).
