What is TWAIN?

TWAIN is the interface that links the scanner with scanning software applications. -TWAIN is an industry standard that enables you to use the ImageReader with any TWAIN-compliant software application.

With the introduction of Windows 95, the TWAIN specification bat been overhauled to take advantage of the 32-bit architecture. When you install our scanner driver under Windows 95, you will have two TWAIN sources - one for 16-bit applications and one for 32-bit applications. Use the following as a guide to select the appropriate source.

16-bit applications are legacy Windows 3.x programs that you are running under Windows 95.

32-bit applications are programs specifically designed for Windows 95, to take advantage of performance en-

hancements provided by the new architecture.

You may experience scanning problems if you do not use the appropriate source.

There is no change to the TWAIN source for Windows 3. 1 x users. Only the 16-bit TWAIN source is installed.

A note about application software

The scanner hardware by itself is not very useful. It takes a combination of the scanner hardware and application software to perform any task. Before you begin scanning, you need to choose the appropriate application to use for the task at hand. Please read this section to,gain an understanding of the types of scanning software there are.

Scanning software generally falls into two groups, Graphics (image editing), or OCR (Optical Character Recognition). Each type has specific features designed to address the technical challenges faced in the scanning of graphics or of text.

Graphics: Software in this category provide’s the user with image editing tools for performing extensive modifications to art, photographs, or other continuous tone images. While having the
