When you want to use multistream settings for scanning

with a single scan operation, and output scanned images with different
scanning conditions for each of the front and back pages (multistream
settings).
When you want to use the multistream settings for scanning, select
the [Use MultiStream] checkbox on the [Others] tab to display the
setting items related to multistream, and then configure the setting
items in the following order.
A When you want to specify different scanning conditions for the front
and back pages of a document, select [Duplex] for [Scanning Side]
on the [Basic] tab in advance.
B Specify the number of scanning conditions to apply in [Stream
count of Front]. Up to three can be specified.
C Select [Front 1st], and then open the other tabs and set the
scanning conditions. Depending on the value specified for [Stream
count of Front], configure the remaining [Front 2nd] and [Front 3rd]
in the same way.
