#24 Barcode not readable

[Szeski]

I have Problem with many Barcodes. F.Example barcode with text:
5000036104d000105659f00.00000000.3
cant be read by my scanner (if I use other PDF417 Generator the same text works with my scanner)

Scanner recognize first 6 letters correctly, dann put "random" numbers and letters (longer then text above), and after '.' is than correct again.
Changing from Capital to Lower or '.' to other character dasn't help.

example:
barcode printed: 9004AD71050000105159F...
barcode scanned: 9004AD53945000094643100F...

Sometimes is also letter "P" generated att the end of barcode!
