Characters are Not Recognized During Conversion to Editable Text (OCR)
If characters in your scanned images are not recognized during OCR conversion, try these solutions:
• Make sure your original is loaded straight on your product.
• Use an original with clear text.
• When saving scanned images as Searchable PDFs, make sure the correct OCR language is selected.
• Adjust the following Epson Scan 2 settings if available, and try scanning again:
• On the Main Settings tab, make sure you select the correct Image Type for your original.
• On the Main Settings tab, set the Resolution between 200 and 600 dpi.
• On the Advanced Settings tab, select Text Enhancement and choose a setting.
Note: The Text Enhancement setting depends on the selected Image Type.
• If the Image Type is set to Black & White, adjust the Threshold setting on the Advanced Settings
tab. (The Image Option must be set to None.)

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.
