IMPORTANT
For SCSI interface users: if you are using other
SCSI devices besides the scanner, see page 2-6
and 2-7 in the TWAIN manual and also see the
SCSI information in the README file on the disk.
The colors in scan previews are not accurate if
your computer supports 256 or fewer colors. This
does not affect the final scan. For optimum
viewing choose True Color as the SCAN MODE on
the Scanner Control screen. For the best
scanning and viewing, Epson recommends using
a True Color (24-bit) video board.
Both the horizontal and vertical dimensions of
the largest scan possible are reduced by 1/2 inch
in the current version of the Epson TWAIN.
Picture Publisher must be set up the first time
you use it. Use the SETUP command in the FILE
pull-down menu. Select ACQUIRE DEVICE and
then select EPSON SCANNERS. To scan a
document, use the ACQUIRE command also
located in the FILE pull-down menu. Do not use
the SCAN command in the FILE pull-down menu
because it does not use Epson TWAIN and it may
lock up your system.
The current version of Picture Publisher (version
3.1) produces a reversed or negative image when
you use the black & white line art setting within
the SCAN MODE. Correct this within Picture
Publisher by selecting the INVERT command
from within the EFFECTS pull-down menu. This
problem will be corrected in later releases of
Picture Publisher.
The current version of Epson TWAIN does not
support all OS/2 version 2.0 applications.

1-2 Installing the Interface Card

Removing the Cover
Follow these steps to remove your computer’s cover:
1. Turn off the computer and any peripheral devices.
2. Disconnect the computer’s power cable from the electrical
outlet and from the back panel. Also disconnect any cables
that are connected to the computer, including the keyboard
cable.
3. Remove the cover. (If you need instructions, see your
computer manual.)
4. Before you touch any of the components, touch an unpainted
metal surface inside the computer’s case to ground yourself
and avoid an electric shock.
Q
Warning
Be sure to ground yourself to an unpainted metal surface in
the computer every time you remove the cover. If you are not
properly grounded, you could generate an electric shock which
could damage a component.
If you are installing an Adaptec SCSI adapter card, skip the
section on checking jumper setting.
Checking the Jumper Setting
One of the jumpers on your Epson bidirectional parallel
adapter card identifies the port address for your bidirectional
parallel port. Follow these steps to unpack the option card and
check the jumper setting:
1. Unpack the option card. When you handle it, be careful not to
touch any of the components on the circuit board or the
gold-edged connector.
Installing the interface Card 1-3

2. Locate jumper J1 on the card. (Ignore the J2 jumper.)
J1
A jumper’s setting is determined by where the jumper is placed
on the pins. It connects either the left pin and the middle
pin or the right pin and the middle pin, as shown below.

Refer to the table below to see which setting is appropriate for
your system.

LPT1
Identifies the port address as LPT1
‘Factory setting
Most people use LPT1 to connect a printer, so you probably
want to leave the jumper at the factory setting so that it
supports the LPT2 address for your scanner.
Note
The TWAIN installation program requires that you identify your
J1 jumper setting on the Epson bidirectional parallel adapter
card as part of the installation process. Make sure you note the
jumper setting before you install the card.
3. If necessary, move the jumper from one position to the other,
using needle-nose pliers or tweezers to pull it off its pins
and gently move it to the desired position.
Caution
Be careful not to bend the jumper pins or damage any
surrounding components on the card.
4. Place the interface card gently on top of its original packing
material with the component side facing up. Keep the
packing materials in case you remove the card later.
Installing the Interface Card 1-5

installing the Card
Your computer has several standard option slots that can
accommodate either the Adaptec SCSI or the bidirectional
parallel adapter card. You can install the interface card in any
available slot. See your computer manual for detailed
installation instructions or follow these general steps:
1. Remove any retaining screws from the metal option slot cover
and remove the slot cover. Keep the screw(s) to secure the
option card to the computer. Store the slot cover in a safe
place in case you remove the interface card later.
2. Grip the interface card firmly by the top corners and make
sure the connector points down.
3. Insert the card into the slot, guiding it straight down. Once
the connector reaches the slot, push the card down firmly
(but carefully) to insert it fully. You should feel the card fit
into place.
4. Secure the end of the card to the back of the computer with
the retaining screw(s).
Replacing the Cover
Follow these steps to replace your computer’s cover:
1. Replace the cover. (If you need instructions, see your
computer manual.)
2. Reconnect the computer’s power cable to the back panel and
then to an electrical outlet. Also reconnect any cables you
disconnected, including the keyboard cable.
1-6 Installing the Interface Card

Connecting the Cable
These procedures describe connecting the bidirectional parallel
adapter cable, then the SCSI adapter cable.
Connecting the Bi-directional Parallel Cable
Follow these steps to connect the cable to your bidirectional
adapter card. This cable came in your Epson Scanner Interface
kit.
1.
2.
3.
4.
Make sure both the scanner and computer are turned off.
Connect the 25-pin end of the cable to the computer, then
tighten the screws on the sides of the connector.
Connect the 36-pin end of the cable to the scanner; then fasten
the connector with the clamps on the sides of the connector.
Turn on your computer and scanner.
You are now ready to install Epson TWAIN.
Connecting the SCSl Cable
The SCSI interface on your computer allows you to connect up
to eight devices, including the computer, in a daisy-chain
arrangement. Only the first SCSI device is connected to the
computer; each of the other devices is connected to the
previous device.
1. Make sure both the scanner and computer are turned off.
2. If the Epson scanner is your only SCSI device, attach the
50-pin connectors to the scanner and your computer.
Fasten the connectors with the clamps on the sides of the
connector.
installing the Interface Card
1-7

You must also set the terminator switch to on or install an
external terminator on one of the two SCSI connectors on
your scanner if the scanner is the last device in the chain.
See your scanner documentation for more information on
terminators.
If you have additional SCSI devices, make sure only the last
device in the daisy chain is terminated. Use cables with
50-pin connectors at both ends, then fasten the connectors
to the scanner and the next device with the clamps on the
sides of the connector.
3. With a SCSI adapter, always turn on the scanner first; then
start the computer.
Warning
Do not connect a parallel and a SCSI interface cable to the
scanner at the same time. Always use shielded cables.
Checking Your SCSI Device Settings
The factory-set SCSI ID of the scanner is 2. The SCSI host
adapter in the computer is normally preset to ID number 7. If
you are going to 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 as described next:
1. Locate the SCSI ID switch next to the SCSI connectors on the
rear panel of the scanner.
