What to do if Datalogic Gryphon GD4200 LED is on but doesn't decode barcode?

If the LED is on, but the bar code does not decode, the reader may not be programmed for the correct bar code type. Check that the reader is programmed to read the type of bar code scanned. Also, verify the bar code label to ensure it is not defaced and try scanning another bar code type. Adjust the distance between the reader and the bar code.
