USING THE TWAIN INTERFACE TO SCAN

The following figure shows the TWAIN interface for scanning from PaperPort and other applications that use the TWAIN standard. Note that some of the options on the window may not be available, and will be greyed out if they are not appropriate for your scanner.

The options for the Visioneer Strobe XP 220 TWAIN interface are:

■Mode—Select a scanning mode:

Black&White to scan in black and white. The scanning pixels are all the same size and are either black or white. Use this setting for letters, memos, and other black and white material. This scan mode produces the smallest file size.

Greyscale to scan items such as documents containing drawings or black and white photographs. The scanning produces an image of up to 256 shades of gray. You can also scan a color document to turn its colors into gray shades. The file size is about one third that of a color scan.

Color to scan magazine articles, photographs, and other color images in full color. Color scans have the largest file size.
