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

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