TWAIN Driver Settings

In the TWAIN driver, the various functions appear as icons. Descriptions of
the various functions are provided below.

Scan Method

You can select how to scan from the Scan Method drop-down list.
Flatbed: Use this setting if you are scanning one page at a time using
the flatbed glass.
Simplex/Multi-page: Use this setting if you are scanning a multi-page
document using the ADF.

Selecting the Proper Image Type

Select the appropriate image type for your purpose through the scanner user
interface.
The different image types are described below.

Black and White

Black and White represents the image in black and white only, without inter-
mediate shades of gray in-between. That means each pixel of the image is
either 100% black or 100% white. Black and White is the best choice of
image type for scanning text or a pen or ink drawing. Since only 1 bit of black
or white information is required for each pixel*, the disk space required for
saving a line art image is only about 1/24 of that required to save a 24-bit
True Color image.
* A combination of the words "picture" and "element," a pixel is a single dot on
a computer display or in a digital image.

8-Bit Gray

A single-channel image consists of at least 256 shades of gray. An 8-bit scan-
ner produces a grayscale image with 1,024 shades of gray between pure
black and pure white. Choose this option for scanning black-and-white photo-
graphs.
