TROUBLESHOOTING

Our scanners are designed to be reliable and easy to install. If, however, you
have a problem with your scanner, these troubleshooting steps should
indicate the cause of the problem.

If the scanner lamp flickers, dims, or fails to come on:

The scanning lamp is failing or has failed and needs to be changed. Please
contact your dealer or our Technical Support.

If the indicator comes on, but software returns a “scanner
link failed”, or a similar message:

1. Make sure the cable is connected properly.

2. Check the installation procedures to make sure you followed all of the

instructions.

If you see the error message “Scanner link failed” when
executing the Preview or Scan commands, or encounter
another system exception event, do the following:

1. Remove the cable from the USB port and re-insert it.

2. Ensure that the cable to the USB port is securely and properly

connected to the USB port.

3. Check the installation procedures to ensure that all the instructions have

been followed.
