The OCR engines will not automatically identify the language in the original document/image, so you must specify the desired language by following the steps below:

  1. Open Processing/Refinement Options
  2. Check "Optical Character Recognition"
  3. Click "OCR Options"
  4. Under Engine select the desired engine
  5. Under Languages select the desired language
  6. Click OK and continue with your processing



  • Only one language may be used for any given OCR job.  That language setting will apply to the full contents of all documents in that job.
  • The LeadToolsAdvantage engine requires an additional license.  Inquiries to obtain this license should be directed to at [email protected] or
