Code 128 Misreading? S’abonner
We are using BarTender to print 8 digits serial number of our products on stickers,
We use code 128 and for years we had no problems getting the desired number to be scanned from the stickers.
Recently we observed two cases in which the serial number was scanned and a different number printed on the PC i.e the input from the barcode scanner was different from the right number which was printed on the sticker (for example if the number start with 14567....the PC recieved the number 04567.... - the 1 was replaced by 0, or in other case about 3 digits were replaced.)
When I tried to reproduce the problem the correct number was scanned without any problems. meaning the right number was printed on the sticker)
Although I've notice the some areas of the bars are erased (usually horizontal lines erased at the bottom of the bars)
My questions are:
1. Do you know of any issues of barcode misreading , I mean not that the number is not read at all but it read wrongly, and if so what in the printing of such code can lead to these errors.
2. I know the code 128 has a check digit (which is marked as enabled by default on the BarTender SW. Is a regular barcode scanner 'knows' how to verify the content according to the check digit (We use Argox scanner AS-8150). is such error is possible if the check digit verification is enabled?
3. What do you recommend us to do in order to investigate this issue and understand the source of the errors?
