Setting the terminator switch
The scanner has a built-in terminator, which allows SCSI devices
to communicate properly with each other. You may need to
change the terminator switch setting according to your computer
system.
Note:
Do not use an external terminator.
The terminator switch is located
at the rear of the scanner.
