Trouble shooting
The scanner will automatically perform a simple self-test
each time it is turned on. This will help spot major system
errors in the scanner itself.
When the test is initiated, the READY LED is flashing. When
the test is completed, if no error occurs, the READY LED is
steadily on.
If you have problems with the operation of your scanner,
please check the following troubleshooting hints.

Question and Answer
Question: The LED indicates that the scanner is ready,
but the scanner does not respond to the
scan command from the host computer.
Answer:
a) Please check if the signal cable is firmly
seated, and invoke the scan command
again. If there is still no response, please
reset the scanner by turning it off and then
on again, and reboot your host computer as
well.
b) Check if the driver is correctly installed.
