Good Morning All I have an issue/curious question. Is there a difference in barcode format "Code 39 Mod 10" and normal "Code 39"? The reason I ask is because by mistake we created half of our barcodes in Code 39 format and the rest in Code 39 Mod 10 format. The weird part is the scanner is reading both and entering the correct value for each but when you submit the Code 39 Mod 10 it says it can't find the barcode but if you scan the Code 39 barcode it works fine. Any ideas? Thanks Ed Edward J. Roche, MCP Network Administrator Solanco School District 717.786.2151 x2437 "At the End of the Day, Did You Play to Win or Not to Lose?"

Code 39 Mod 10 includes a Mod 10 checksum and so is different. Code 39 is known as a "self-checking" format and so really does not need a checksum.
The weird part is the scanner is reading both and entering the correct value for each but when you submit the Code 39 Mod 10 it says it can’t find the barcode but if you scan the Code 39 barcode it works fine.
I'm guessing a little here, but you probably have to setup your scanner for Code 39 Mod 10 in order to get the checksum digit decoded properly. Personally, I think I'd whip up a script to change the Code 39 Mod 10 barcodes to plain Code 39. Kind Regards, Chris
Hi Eric I emailed the manufacture of the scanner and they confirmed that the Mod 10 uses the checksum character and that I can configure it to ignore the this character but for some reason when I do this now it won't read the regular Code 39 or the Mod 10 barcodes. Have you seen this happen before? Thanks! Ed Edward J.
