shaded backgrounds, run-
together or broken text

Recommendations for Scanning
• Select 3D OCR in the Accuracy settings if you
have a grayscale scanner.
• Experiment with the Manual Brightness setting to
get a good scan if you have a black-and-white
scanner. Lighten the setting for thick, run-together
text characters and/or dark backgrounds. Darken
the setting for thin, broken text characters.
• Try to scan original documents rather than copies.
Other Recommendations
• Select Use Language Analyst in the Accuracy
settings. OmniPage Pro will evaluate words and
make logical replacements for hard-to-recognize
characters.
• Draw zones manually to omit any smudges or
scribbles on the page.
• Choose Check Recognition... in the Tools menu to
locate possible errors after OCR.
• Ask senders to select
Fine or Best mode when they
send faxes that you plan to recognize.
