I’m having an issue with the barcode reader only being able to scan 1 of the 2 scannable barcodes. Both barcodes are the same number, but one is slightly larger. The gun is used for shipping and manifest.

I am using 1 gun on the dock with multi interface connection.

The RED is scanning fine, but the blue is what I also want to scan.

I had such an issue and had to swap out the gun. This was upsetting to the company as they wanted it to not be a hardware issue but the gun was a decade old so it actually did well.

BE SURE to clean the gun lens inside and out. Sometimes I find dust on the inside which degrades its performance.
