Question: When I power on the scanner, the lamp
does not light.
Answer: The possibilities are as follows:
a) The lamp is out of order. In that case,
contact your authorized local dealer to
change the lamp. The life time of the lamp
is about 5000 hours.
b)
Check whether the power LED on ADF
cover steadily lights or not.
If it flashes, the power adapter malfunctions
or the main board is short-circuited.
Contact your authorized local dealer to
replace the power adapter or main board.
Question: Getting image from the scanner is not a
problem, but when scanning, the scanner or
system will often crash.
Answer: Please check

firmly seated;
b) Only two SCSI terminators can be connected
to your SCSI daisy chain. One is at the end of
the SCSI device, and another is already in your
host adapter.
Question: The scanned image always comes out to be
too dark.
Answer: a) Use your application to modify the
Gamma setting to 2.2 and 1.8 for your
printer and monitor respectively.

Use Brightness setting from the TWAIN
user interface to get a brighter image.
