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.
