What to do if the Symbol LS 4008i Barcode Reader laser comes on, but the symbol does not decode?

If the laser comes on but the symbol doesn't decode, it could be due to several reasons. First, ensure the Symbol Barcode Reader is programmed to read the specific type of barcode you are scanning. Second, check the barcode symbol itself to make sure it is not damaged or defaced. Try scanning test symbols of the same barcode type. Finally, adjust the distance between the scanner and the barcode; try moving the scanner closer or further away from the barcode.
