Select Basic or Advanced from the list to show the basic or advanced document source configuration options as
described below.
Basic Options
• Duplex —select this option to scan both sides of the item in the scanner.
Click the drop down menu to select the color mode you want to use.
• 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.
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.
