  If the LED is on but the barcode isn't decoded, there could be a few reasons. First, ensure the reader is programmed to read the type of barcode you're scanning. Second, check that the barcode label isn't damaged. Try scanning a different barcode. Lastly, adjust the distance between the reader and the barcode; move the imager closer to or further from the barcode.

What to do if Datalogic QW2520 decodes but doesn't transmit to the host?

  If the barcode reader decodes the barcode but doesn't transmit it to the host, the imager might not be programmed for the correct host type. Scan the appropriate host type barcode to resolve this issue.
