6. Troubleshooting
The scanner will automatically perform a simple self-test
each time it is turned on. This helps spot major system
errors in the scanner itself.
During the test, the READY LED and ERROR LED will light
on and the scanner reading head will move a bit forward.
Once the test is finished and if no error occurred, the READY
LED will stay solid and the ERROR LED will extinguish and
the scanner reading head will back to its leftmost position.
If you have problem with the operation of your scanner,
please check the following troubleshooting hints.
