What character set are you using?  You need to create one if you haven't.  OCR is basically a form of pattern match.  Here is thread describing how to do this:  http://forums.ni.com/t5/LabVIEW/how-to-create-character-set-file/td-p/1130815

 

Have you seen the OCR examples in the NI Example Finder?  Go to Help>>Find Examples... and then type in "OCR" in the search.
