When a barcode scanner don’t work suddenly, The first thing you should do is to find out the situation. Is it the situation that the scanner can scan barcode normally but without data uploading ? If so, It means that the computer and the scanner are not connected. then you can try to check the port and cable if it is wired. If it is wireless, you should reset the paired receiver.
