20.12Barcode scanner malfunction

If there is no red scanning beam when the trigger is pulled, tug on the cable where it enters the scanner. If it comes loose easily, push it back in until it clicks in place.

If the scanning beam stays on when the trigger is released or if the barcode scanner fails to read known good barcodes, try the following:

1)Unplug the scanner from the RM500SL, then reconnect it. If the problem persists…

2)Print this page on an external printer (see 2.7: External printer, auxiliary audio outputs) or from the electronic user’s guide on the RM500SL software CD (see 1.3: Electronic user’s guide).

3)Scan these two barcodes, starting with the top one. This will reset the scanner to its default settings.
