Avision AV100CS - Manual (Page 40)

6-3
Question: Why is it my scanned image always comes out too
dark?
Answer: 1) Modify the Gamma setting to 1.8 for your
monitor and, when printing, set Gamma to 2.2
for your printer.
2) Use the Brightness setting of the TWAIN user
interface to get a brighter image.
Question: Sometimes it seems the scanner does not detect
paper?
Answer: The AV100CS scanner paper sensor is located at
the center of the paper guide. Please place the
document you need to scan on the paper guide
and use the slide guides to keep the paper path
straight.
Question: To get image from the scanner is no problem. But
when scanning, the scanner or the system will often
crash.
Answer: 1) Please check that the cable is firmly seated.
2) Only two SCSI terminators can be connected
to your SCSI daisy chain. One is at the end of
the SCSI device, the other already in your host
adapter. (Please see Section 2-3 for more
details.)
