2 Introduction

❑Connect all equipment to properly grounded power
outlets. Avoid using outlets on the same circuit as
photocopiers or air control systems that regularly switch on
and off.
❑Do not let the power cord become damaged or frayed.
❑If you use an extension cord with the scanner, make sure the
totalampere rating of the devices plugged into the extension
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
A-Überstromschalter abgesichert ist.

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.
❑Keep the scanner away from high temperature and
humidity. Also avoid using or storing the scanner in places
subject to rapid changes of temperature and humidity.
❑Keep the scanner away from direct sunlight and strong
light sources.
❑Avoid places subject to shocks and vibrations.

1-2 Setting Up the Scanner

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.
3. Push the screw into the storage hole marked STOCK. It does
not screw in. Make sure you push it all the way into the
hole.
Note:
Do not discard the transportation screw. It must be replaced when
storing or transporting the scanner.

1. Make sure that the scanner is turned off. It is off when the
OPERATE button protrudes from the surface of the front
panel.
2. Connect the power cable to the power inlet on the rear of the
scanner and plug the other end into a properly grounded
outlet.
cCaution:
It is not possible to change the scanner’s voltage. If the

Initialization
Before connecting the scanner to your computer, follow the
steps below to make sure that the scanner is operating properly.
1. Open the document cover so you can see the operation of
the scanner during initialization (startup).
2. Turn on the scanner by pressing the OPERATE button. The
OPERATE light comes on.
3. Make sure the fluorescent lamps on the carriage flash, and
the carriage moves slightly.
4. The READY light comes on. This means the scanner has
completed its initialization.
5. Turn off the scanner.
If the scanner does not work as described, make sure that the
power cord is firmly plugged in and that you have removed
the transportation screw, then try again.
cCaution:
Whenever you turn off the scanner, wait at least 10 seconds
before turning it back on. Rapidly turning it on and off can
damage the scanner.

Setting Up the Scanner 1-5

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.
If you add the scanner to a system in which one of your SCSI
devices already has a SCSI ID of 2, change the ID number of the
scanner to an unused number. See the table on the next page as
a guide.

cCaution:
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.
