TWAIN Scanning Guide Document Source Configuration
14 User’s Guide
Advanced Options
• Multi-stream—select this option to have the scanner create an image of each item scanned
in each color mode selected in the source list.
• Duplex—select this option to scan both sides of the item in the scanner. Note that if you
deselect the Back side options in the source configuration list, this option will automatically
deselect.
Click the drop down menu to select the scanning options you want to use.
The available color modes are:
• Automatic determines the color of the document as it is being scanned.
• Color scans the document in color, creating a full color copy of an original document or
photograph. Color scans have the largest file size.
• Gray scans the document using varying shades of gray to reproduce the document. The
grayscale scan mode is often used when scanning documents or graphics where the original
color does not need to be retained, but the graphics need to be legible. Grayscale scanning
preserves the graphic quality while keeping the file size less than that of a full color scan.
• Black and White scans the document in bitonal where everything on the page is either black
or white. This setting is often used when scanning typed or written documents. When there
are not a lot of graphics, or if the graphics are not needed, this setting is ideal for archiving
documents to a server or on a disc, send through email, or posting to a web page, as the file
size is smaller than the other scanning modes.
Sides Identical
If the scanner supports two-sided (duplex) scanning, you can individually set the color mode and
other options in the scanner interface for each side of the page. This option is always selected and
grayed out if the scanner hardware does not support the feature.
