Error: "OCR module failed - Failed to replace document pages"

Applies to:

Revu 20 & below

Problem

When trying to run OCR, Revu displays the OCR Module report dialog with the following errors:

  • OCR module failed
  • Failed to replace document pages

Cause

These errors occur in either of the following conditions:

  • The PDF is too large or has too many pages.
  • The Windows user name contains special characters (such as @ # * _ ^ & +).

Solution 1: The PDF is too large or has too many pages

  1. Select Document > OCR.
  2. In the OCR dialog, select Page Chunk Size and set the field value to "1".
  3. Click Save to run OCR.

Solution 2: The Windows user name contains special characters

Determine whether the Windows user name contains a special character. If so, create a new profile that contains no special characters. This change will allow the OCR module to run successfully.
