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 &

❑

Introductio n

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

❑
