   // The bank cheque image 
   string chequePath = Path.Combine(LEAD_VARS.ImagesDir, "BankCheck.jpg");

   //Set MICR code type 
   checkReader.MicrFontType = BankCheckMicrFontType.E13b; 
 
   // handle Process Event 
   checkReader.Process += new EventHandler<ProgressEventArgs>(reader_Processed); 
 
   // Process Image
