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✽)

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.
