Note
Epson TWAIN supports the built-in bidirectional parallel
interface on the IBM PS/2. If you have a PS/2, you don’t need
to install an additional interface card. Turn to Chapter 2 for
instructions on installing Epson TWAIN. You must install
either the bidirectional parallel interface or the Adaptec SCSI
adapter for all other computers.
Procedures for installing the bidirectional parallel or the
Adaptec SCSI adapter cards differ slightly. You may want to
refer to your computer’s documentation for more complete
instructions on installing option cards.
This chapter contains the following sections. The checkmarks
indicate which sections apply to installing a bidirectional

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.
Warning
Q
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.

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.)

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.

TWAIN.
Basic Scanning With Epson TWAIN
Epson TWAIN provides some predefined settings that allow
you to scan images quickly and see the results on the screen.
For high-resolution scanning, see “Changing Your Scanning
Resolutions.” For other features, see “Using Epson TWAIN’s
Advanced Features.”
Setting Epson TWAIN Options for Your Image Type
Scanning images with satisfactory results depends on knowing
the type of image you are scanning and then using the Epson
TWAIN options required by that type of image.
Using TWAIN 3-3
Epson TWAIN provides two important selections, Scan Mode
and Target Device, that work together to determine how your
image is scanned. When you are using Epson TWAIN, make
sure you pay particular attention to the settings for these two
options.
If you are scanning color images, you may want to install a true
color or 24-bit video card in your computer for the best results.
Follow these steps to select the Epson TWAIN options that are
best for the type of image you are scanning.
1.
Determine whether your image is color, a black and white
photograph (also called gray scale), or black and white line
art. If you need more information on these image types, see
your scanner manual.
2.
Use the chart below to identify the scan mode for your image
type.
If Image Type is

Black and white line art
3.
Use the pull-down menu for Scan Mode to select the scan

mode you want.
4.
If the Target Device setting on the Scanner Control screen is
not VGA Screen, use the pull-down menu for Target Device
to select
VGA Screen.
Previewing Your Image
Epson TWAIN displays a preview of the image you want to
scan. Follow these steps to preview your image.
3-4 Using TWAIN
1.
Place the image you want to scan face down on the scanner.
2.
Select Preview. After several seconds, the rectangle on the
right of the Scanner Control screen shows the image. Note
that the preview colors may not be accurate unless you
have a true color (24-bit) video card. Wait until you have
scanned the image to judge the colors.

Selecting the Scanning Area
If you want to scan only a portion of the image, follow these
steps:
1.
Move the cursor into the preview box.
2.
Hold down the mouse button and drag the cursor until the
box encloses the area you want to scan.
3.
Release the mouse button.
Once you have defined the scanning area, you can redefine it,
move it, or reselect the default.
Using TWAIN 3-5
To define a new scanning area, move the cursor to the edge of
the box until you see a double arrow; then hold the mouse
button down while you drag the edge of the box to a different
position. To reselect the default, click outside the selected
scanning area but within the image.
To move the scanning area, move the cursor to the center of the
scanning area. The cursor becomes a hand icon. Hold the
mouse button down and drag the box to a different position.
When the image is what you want, you can then scan or select
Preview again to see the new scan area.
Adjusting the Brightness
If the preview of your image appears too dark or too light, you
can adjust the Brightness scroll bar on the Epson TWAIN
Scanner Control screen to make your image lighter or darker.
Brightness values range from -3 to +3. To lighten a dark
original, use -1 to -3. To darken a light original, use +1 to +3.
Adjusting the Magnification
If you want to increase or decrease the size or scale of your
image, you can use the Magnification scroll bar on the Epson
TWAIN Scanner Control screen to select sizes from 50% to
200% of the original.
The size you select is not reflected in the preview scan but is
reflected in the final scan. Also, the size of the image on the
monitor is only an approximation of the actual size of the
image when printed. The Width and Height settings on the
Scanner Control screen show the exact size of the image.
3-6 Using TWAIN
Checking the Size
Three options on the Scanner Control screen allow you to see
the size of the image you are scanning. The Width and Height
options allow you to see the size of the selected image while the
Units setting allows you to select inches, centimeters, or pixels
as your units. The Memory setting allows you to see the
memory requirements for the selected scan.
Scanning Your Image
Once you have adjusted the Epson TWAIN settings to suit your
needs, you can scan the image by selecting Scan. After several
seconds, Epson TWAIN places the scanned image in your
application.
Changing Your Scanning Resolutions
You may want to change your scanning resolutions to provide
the best results possible for the printer or other output device
you are using. The following table provides some resolution
guidelines for you to consider. Your scanner manual also
provides detailed information on resolutions.

Select the form of the image data. Each option
below identifies a data format that specifies the
number of bits used to represent the tone of a pixel.
The more bits per pixel, the more tones and colors
you can capture in the scanned image. The
highest number of bits possible is 24 bit color (or
True Color), which can represent over 16 million
colors.
Note, however, that the output devices you use
should be capable of producing the same tones.
Also, the larger the bits per pixel value chosen, the
larger the size of the Image data.
Possible values are:

Editing the Target Device Settings
Epson TWAIN provides several target device definitions you
can use or edit to suit your needs. In addition to Gamma
Correction and Color Correction settings, the Target Device
screen allows you to edit Resolution settings.
You may want to use only the VGA Screen target device or the
target devices you defined to change resolutions, for example,
“VGA with 200 DPI.”
When you scan an image using the VGA target device option,
you get the best quality scan. Your image editing software can
then provide the output settings appropriate for your output
device.
If you are scanning a color image and you select a target device
other than a VGA option, the colors displayed may not match
the colors in the original.
If you get poor color quality from a dot matrix or ink jet printer,
try re-scanning the image using a different target device, such
as LQ printer or Thermal printer. The colors on the screen will
be inaccurate, but your color printout will be better.
