Introduction
The EPSON®GT-12000 is a true 800-dpi full-color flatbed image
scanner with an A3 or US B size scanning area. It has the ability
to scan in color or grayscale, making it ideal for virtually all
uses, from simple drawings to complex full-color illustrations.
It achieves extremely high quality in color by reading and
saving 36 bits per pixel.
Features
The GT-12000 offers the following features:
❑Full color or grayscale scanning. For color scanning, you
can select up to 16 million colors. For grayscale, you can
select up to 256 grays.
❑Scanning resolution of 800 dpi. You can adjust the output
resolution to match the resolution of your output device.
❑Automatic Area Segmentation (AAS) provides you with
the capability to separate text from photographs on a page
so that grayscale images will be clearer and text recognition
is more accurate.
❑Text Enhancement Technology. This feature enhances text
recognition accuracy when using your scanner for optical
character recognition (OCR) scanning.
❑Two resident interfaces, bidirectional parallel and SCSI.
Using these interfaces, you can connect two computers to
the scanner at the same time.
❑Higher quality output with EPSON TWAIN Pro’s “Best &
de-screening” option, which automatically removes
unwanted moiré patterns from scanned images.

Introduction 1

❑The EPSON TWAIN Pro software helps let you take full
advantage of your scanner’s advanced features.
❑Software control of all scanner functions. Software
commands are backward compatible with the EPSON
GT-12000 color image scanner.
Options
The following optional items are available to expand the
versatility of your scanner. For detailed information on the use
of these options, see the guides that come with the options.
Bidirectional Parallel Interface Board (B80818✽)
This board provides parallel connection between the scanner
and IBM®PC/AT or IBM-compatible computers. Setup and
installation of this board are fully described in the manual that
comes with the board. An interface cable must be purchased
separately.
Auto Document Feeder (B81311✽)
This option is designed primarily for optical character recognition
(OCR) scanning. The automatic document feeder allows you to
scan up to 30 pages automatically. You can then use them in a
word processing program just as if you had typed them yourself.
Transparency Unit (B81310✽)
This option allows you to scan transparent materials, primarily
35mm slides and black-and-white negatives. It has a maximum
reading area of 290 ×420 mm, which allows you to scan
transparent materials up to A3 or US B size.
SCSI System Cable (25-pin to 50-pin) (B860081)
This cable provides connection between a SCSI device and an
Apple®Macintosh®computer.

❑If you use an extension cord with the scanner, make sure
the total ampere rating of the devices plugged into the
extension cord does not exceed the cord’s ampere rating.
Also, make sure the total of all devices plugged into the
wall outlet does not exceed 15 amperes.
❑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.
❑Place your scanner close enough to the computer or
workstation for the scanner cable to reach both ends.
❑Place the scanner where you can easily unplug the power
cord.
❑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.
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 be
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 temperatures 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.

Plugging in the Scanner
1. Connect the power cable to the power inlet on the rear of the
scanner and plug the other end into a properly grounded
outlet as shown below.
cCaution:
There are several versions of this scanner designed for
different voltages, and it is not possible to change the
voltage. If the label on the back of the scanner does not
show the correct voltage for your country, contact your
dealer.
2. If any of the scanner’s lights come on, press the OPERATE
button to turn the scanner off.
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.

Initialization
By observing the scanner’s initialization, you can make sure
that the scanner is operating properly before you connect it to
your computer.
1. Open the document cover so you can see the operation of
the scanner during initialization.
2. Turn on the scanner by pressing the OPERATE button.
While the scanner initializes, the fluorescent lamps on the
carriage flash. If the carriage is not at the home position (the
left of the scanner), it moves to the home position.
When the scanner has completed its initialization, the READY
light comes on. If the scanner does not work as described, turn
it off. Make sure that the power cord is firmly plugged in and
that you have released the transportation lock screw, then turn it
on again.

Setting Up the Scanner 1-5

Connecting the Scanner to Your Computer
Your scanner has both a bidirectional parallel interface and a
SCSI interface. You can connect both kinds of interface cables
to the scanner at the same time. The scanner switches
automatically to the appropriate interface.
❑For a PC, do one of the following:
Connect the computer to the scanner’s bidirectional
interface using a shielded, twisted-pair parallel interface
cable. Install a bidirectional parallel interface board in
your computer, if necessary.
Note:
IBM PS/2®computers and many other PCs have built-in
bidirectional parallel interfaces. You do not need to install an
additional one in these computers unless you need the built-in
parallel interface for your printer.
Connect the computer to the scanner’s SCSI interface.
Install a SCSI interface board in your computer, if necessary.
❑For a Macintosh computer, connect the scanner to your
Macintosh’s built-in SCSI port.
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.
