OCR Problems
This section contains information and solutions for possible OCR
problems. Topics include:
• Crash During OCR
• Text Does Not Get Recognized Properly
• Problems With Fax Recognition
Crash During OCR
Try these solutions if a crash occurs during OCR or if processing takes a
very long time:
• Check the quality of the image you are recognizing. See “What is
the quality of the original document?” on page 85 for more
information.
See “Scanning Tips” in the previous section for ways to improve
the quality of scanned images.
• Break complex page images (lots of text and graphics or elaborate
formatting) into smaller jobs. Draw zones and perform OCR on
one page area at a time.
• Resolve low memory problems. See “Low Memory Problems” on
page 112 for more information.
• Resolve low disk space problems. See “Low Disk Space
Problems” on page 113 for more information.
• Restart your computer and test OmniPage Pro by performing
OCR on the Test TIFF.
• Reinstall OmniPage Pro.
Text Does Not Get Recognized Properly
Try these solutions if any part of the original document is not converted
to text properly during OCR:
• Look at the original page image and make sure that all text areas
are enclosed by Text or Automatic zones.
• Make sure the zone contents files assigned to zones contain all
the characters you need. See “Specifying Zone Contents” on page
101.
• Select Use Language Analyst in the OCR section of the Settings
Panel if your main dictionary matches the language of your
document. The Language Analyst evaluates words and corrects
likely errors during OCR.
• Train OmniPage Pro to recognize text characters that are not
being recognized properly. See “Training OCR for Special
Characters” on page 103 for more information.
