What to do if the Symbol LS1900 Barcode Reader laser is on but not decoding?

If the Symbol Barcode Reader's laser turns on but fails to decode the symbol, it might not be programmed for the correct barcode type. Ensure the scanner is programmed to read the specific barcode you are using. Alternatively, the barcode itself may be unreadable. Inspect the symbol for any damage and try scanning known good test symbols of the same barcode type.
