•
Be sure to use the USB cable which
comes as an accessory with this
scanner.
We does not confirm the correct
operation of a commercial USB cable.
•
When connecting to a USB hub, use the
first stage USB hub that is closest to the
computer. If you use the second or later,
the scanner may not operate correctly.

This scanner is provided with two
interfaces: SCSI-2 and USB1.1.
On this scanner, each of the SCSI and
USB interfaces is controlled exclusively,
so both interfaces cannot be used
simultaneously. Scanner can be only
connected to either USB or SCSI
interface.
