❑
If you use an extension cord with the scanner, make sure the
❑
total a mpe r e r ating of the de vi c es pl ug ge d i n to t h e ex te nsion
cord does not exceed the cord’s ampere rating. Also, make
sure the total ampere rating of all devices plugged into the
wall outlet does not exceed the wall outlet’s ampere rating.
Except as specifically explained in this user’s guide, do not
❑
attempt to service the scanner yourself.
Unplug the scanner and refer servicing to qualified service
❑
personnel under the following conditions:
If the power cord or plug is damaged; if liquid has entered
the scanner; if the scanner has been dropped or the cabinet
damaged; if the scanner does not operate normally or
exhibits a distinct change in performance. Adjust only those
controls that are covered by the operating instructions.
If you plan to use the scanner in Germany, observe the
❑
following:
To provide adequate short-circuit protection and
over-current protection for this scanner, the building
installation must be protected by a 16 Amp circuit breaker.
Note for German-speaking users:
Bei Anschluß des Scanners an die Stromversorgung muß
sichergestellt werden, daß die Gebäudeinstallation mit einem 16

Choosing a Place for the Scanner
Follow the guidelines listed below when selecting a location for
your scanner:
Place the scanner on a flat, stable surface. The scanner will
❑
not operate properly if it is tilted or at an angle.
Place the scanner close enough to the computer for the
❑
interface cable to reach it easily.
Allow some space behind the scanner for the cables, and
❑
make sure to place the scanner where you can easily
unplug the power cord. Also allow sufficient space above
the scanner so that you can fully raise the document cover.

Removing the Transportation Screw
Before connecting the scanner to a power source, you must
remove the transportation screw.
1. Place the scanner on a flat, stable surface with its rear panel
facing you.
2. Remove the screw located in the middle of the rear panel by
turning it counter-clockwise, as shown below. If necessary,
turn the screw with a coin or screwdriver to loosen it.

Connecting the Scanner to Your Computer
For PC users:
If your PC does not have a SCSI board installed, you need to
install one according to the directions that come with the SCSI
board. If your PC already has a SCSI board, connect the scanner
as described in the next section.
Note:
If you use Windows 95 or NT, install the SCSI driver included in
Windows 95 or NT (see your system documentation for instructions)
or the driver described in the SCSI board installation documentation.
If you use Windows 3.1, install the driver packed with the SCSI
board, as described in the SCSI board installation documentation.
For Macintosh users:
All Macintosh computers have SCSI ports; you do not need to
install a SCSI board in a Macintosh. Follow the directions below
to connect your scanner and computer.
Understanding SCSI connections
Read the following sections to help determine how to set up
your SCSI device(s) and if you need any optional SCSI cables.
Daisy Chain
The SCSI interface allows you to connect up to seven devices
(such as scanner, hard disk, CD-ROM, and so on) to the
computer, in what is called a “daisy chain” arrangement. Only
the first SCSI device in a daisy chain is connected to the
computer; each of the other devices is connected to another
SCSI device.
1-6
Setting Up the Scanner
SCSI Cables
Before purchasing a SCSI cable or setting up your SCSI daisy
chain, be sure your SCSI cable(s) has the right combination of
50-pin and 25-pin connectors. The combination you need varies
depending on the maker of your SCSI device and SCSI
interface board.
SCSI ID
and
terminator
Each device has a SCSI ID number: the computer is usually
number 7, and each of the other devices must have a different
number between 0 and 6. Also, the first device and the last
device in the chain (not including the computer) must have
a terminator. No other device can have a terminator or if a
terminator does exist, it must be turned off.
Setting the SCSI ID number
The scanner’s default SCSI ID number is 2.

Caution:
c
Do not set the SCSI ID to an ID number that is already
assigned to another device. Otherwise the computer,
scanner, and other devices will not function properly.
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.
