What to do if Datalogic Barcode Reader LED is on but not decoding?

  Savannah SanfordAug 7, 2025
  If the LED is on but the barcode isn't decoding, it could be due to several reasons. First, the reader might not be programmed for the specific barcode type you're scanning, so ensure it is properly programmed. Second, the barcode label might be damaged or unreadable; check the label or try a different barcode. Finally, the distance between the reader and the barcode could be incorrect; try moving the reader closer or further away from the barcode.

  If nothing happens when you pull the scan button on your Datalogic Barcode Reader, the issue might be due to a lack of power or loose connections. Check the system power and ensure the power supply is properly connected. Also, make sure all cable connections are secure.

  If nothing happens when the reader is on the cradle (no start-up, blinking LEDs, or charging), there might be foreign objects on the base surface causing incorrect positioning of the reader. Remove any foreign objects and ensure the base surface is clean.

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