Urgent! BP OCR VIN# Indetification issues

Hi Guys,

I am trying to use BP OCR to read a printed fax form. I was able to read text with OCR for almost every printed text in the form, how ever reading the alphanumeric Vehicle VIN# is giving me wierd results. For eg VIN# F1269ASX87715BCZ0 is not been read accurately. I tried incrementing the Scale by 0.1 for almost 60 iterations but no luck. I an using Scale and Language "Eng" as my identifiers. Is there some other techinque that i should try?
