For PC users:
Unless your PC already has a SCSI board installed, you need to install one, along with
SCSI driver software. Install the SCSI board according to the directions included with
it. Also see "Installing a SCSI interface board" in your online Setup Guide.
Note:
You will also need to install the SCSI driver that is normally included with Windows
(see your Windows documentation for instructions), or the driver described in your
SCSI board installation documentation.
For Macintosh users:
Your Macintosh may or may not have SCSI ports, depending on which model you own.
See "Installing a SCSI interface board" in your online Setup Guide if you need to install
a SCSI board in your Macintosh. If your Macintosh already has a SCSI port, install the
scanner software as described in Chapter 3 of the online Setup Guide, then connect the
scanner to your Macintosh as described in "Connecting the scanner" in your online
Setup Guide.
Note:
The latest driver may be available for download from the Web site of the SCSI board
manufacturer.
