A Note Concerning Responsible Use of
Copyrighted Materials
Like photocopiers, scanners can be misused by improper scanning of copyrighted
material. Although Section 1070f the U.S. Copyright Act of 1976 (Title 17, United States
Code), the “fair use” doctrine, permits limited copying in certain circumstances, those
circumstances may not be as broad as some people assume. Unless you have the advice of
a knowledgeable attorney, be responsible and respectful by not scanning published
material without the permission of the copyright holder.

SCSI interface. Cables can be connected to both interfaces at the
same time. The scanner automatically switches to the
appropriate interface.
0
To connect the scanner to a PC, do one of the following:
Install a bidirectional parallel interface board in your
computer, if necessary. Then connect the computer to the
scanner’s bidirectional interface as described in the next
section.
Setting Up the Scanner
1-5
Note:
IBM® PS/2® computers and some other PCs have built-in
bidirectional parallel interfaces. You need to install an additional
one in these computers only if you use the built-in parallel
interface for your printer.
Install a SCSI board in your computer, if necessary. Then
connect the computer to the scanner’s SCSI connector as
described under “SCSI Setup” on page 1-8.
0
To connect the scanner to an Apple® Macintosh® computer,
you do not need to install a SCSI board in your computer;
simply connect your scanner to your Macintosh’s built-in
SCSI port as described under “SCSI Setup” on page 1-8.
To use an interface correctly, you may need to change settings
on the scanner, computer, or both. The following sections
explain how to set up and connect each type of interface.
Connecting the Scanner to a Parallel Interface
To connect the scanner to a parallel interface on your computer,
use a standard shielded parallel interface cable and follow the
steps below.
1-6
Caution:
The scanner’s bidirectional parallel interface requires a
bidirectional interface on your computer. Check your
computer’s specifications to see if its built-in parallel interface
is bidirectional.
1.
Make sure that both the scanner and computer are turned
off.
Setting Up the Scanner
2.
Connect the 25-pin end of the cable to the computer; then
tighten the screws on the sides of the connector.
3.
Plug the 36-pin end of the cable into the scanner’s parallel
interface connector. Then squeeze the wire clips together
until they lock in place on both sides.
Note:
If your parallel cable has a ground wire, attack it to the scanner’s
ground terminal.
Setting Up the Scanner
1-7
SCSI Setup
For some PCs, you must first install a SCSI board in your
computer. All Macintosh computers have built-in SCSI ports;
you do not need to install a SCSI board. Follow the directions
below to connect the scanner to your PC or Macintosh.
SCSI connections
The SCSI interface allows you to connect up to eight devices,
including the computer, in 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 the
previous device.
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
terminators. If any other devices in the chain have terminators,
the terminators must be turned off. The scanner has two 50-pin
SCSI connectors and a built-in terminator that you can turn on
or off.
Setting the SCSI ID number
The factory-set SCSI ID number of the scanner is 2. The
computer’s SCSI ID number is usually 7. If one of the SCSI
devices in your system already has the SCSI ID number 2,
change the scanner’s SCSI ID number to an unused number as
described on the next page.
1-8
Setting Up the Scanner
1.
Locate the SCSI ID rotary switch on the rear panel of the
scanner.
2.
To change the scanner’s SCSI ID, turn the dial to the desired
number.
Caution:
Do not set the scanner’s SCSI ID to a number that is
already assigned to another device; the computer, scanner,
and other devices will not function properly.
Note:
If your software supports only the ES-1200C scanner, set the dial
to the position marked * to select ES-1200C Emulation mode. In
ES-1200C Emulation mode, the scanner’s SCSI ID number is 2.
If one of your other SCSI devices already has the SCSI ID
number 2, change that device’s number to an unused number.
Setting Up the Scanner
1-9
Using the termination switch
The scanner has a built-in SCSI terminator. If the scanner is the
only SCSI device you connect to your computer or if it is the
last device in the daisy chain, leave the termination switch
turned on.
If the scanner is in the middle of a daisy chain, turn off the
termination switch.
Connecting the scanner to your computer or to another
SCSI device
To connect the scanner to a Macintosh, use a SCSI cable with a
25-pin connector on one end (for the computer) and a 50-pin
connector on the other end (for the scanner). To connect the
scanner to a PC or another SCSI device, use a SCSI cable with
50-pin connectors on both ends. Connect the scanner as
follows:
1.
Make sure that the scanner, the computer, and all other SCSI
devices are turned off and unplugged from the power
source.
1-10
Setting Up the Scanner
2.
Connect the 50-pin end of the cable to either the top or
bottom SCSI connector of the scanner; then squeeze the
wire clips together until they lock in place on both sides.
3.
Connect the other end of the cable to the SCSI port of your
computer or other SCSI device.
Note:
The SCSI port of the Macintosh is the larger port with the
SCSI icon
4.
Plug in the power cables of your computer, scanner, and
other external SCSI devices.
5.
Turn on the scanner and any other external SCSI devices
before you turn on your computer.
Turning on your computer and external SCSI devices
Always follow the power-on sequence described here when
you turn on your computer and external SCSI devices.
If you have an internal hard disk, turn on the scanner and any
other external SCSI devices you plan to use. Wait a few
seconds; then turn on the computer.
