6. TROUBLESHOOTING

The scanner will automatically perform a simple self-test each time
it is turned on.  This will help to spot major system errors in the
scanner itself.

When the test is initiated, the READY LED is flashing.  When the test
is completed, the READY LED is steadily on.

If you have problems with the operation of your scanner, please
check the following troubleshooting hints.

6.1 FREQUENTLY ASKED QUESTIONS

Question:   The LED indicates that the scanner is ready, but the

scanner does not respond to the command from the

host computer.

Answer:

Please check your SCSI ID# and SCSI terminator (See

Chapter 2 Scanner Installation) and make sure that the

power cable and SCSI card or SCSI cable have all been

correctly and firmly connected(See also Chapter 2).

Then, try the Scan command again, if there is no

response, please reboot the host computer as well as

reset the scanner by turning it off and then on again.
