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.
• Adjust these Epson Scan 2 settings (if available) and try scanning again:
• Select the correct Image Type setting.
• If the Image Type is set to Black & White, select Text Enhancement. If the Image Type is set to
Color or Grayscale, change the Text Enhancement setting to High.
• Select or adjust the Text Enhancement setting.
• If the Image Type is set to Black & White, adjust the Threshold setting.
• Set the Image Type to Grayscale.
• Set the scanning resolution between 200 and 600 dpi.
• If the original document is in landscape mode, set the Rotate setting to Auto in Epson Scan 2.
• If you are using OCR software, check the manual for any additional adjustments.
• Scan thermal paper receipts as soon as possible. They may deteriorate due to age or friction.
• When saving to Microsoft Office or Searchable PDF files, check that the correct languages are
selected. Check the language in each save setting window.

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 Settings tab.
• Select a lower Resolution setting.
