About MultiStream Functions
If your scanner supports MultiStream functions, you can scan two different types of image data (such as
color and black and white or grayscale and black and white) at once, and output the different types of image
data for the front and back of a page.
The MultiStream Settings dialog box is available if your scanner supports the MultiStream function, by
selecting MultiStream Settings in the Options menu or the
Scan Batch to File Setting ( →P. 40) dialog box.
Note
MultiStream functions are disabled when Mode is set to Auto Color Detection in the scanner settings.
