A When you want to specify different scanning conditions for the front 

and back pages of a document, select [Both] 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.

D When specifying the scanning conditions of the back, configure the 

settings in the same way as described in B to C. In this case, 
specify [Stream count of Back], and then set the scanning 
conditions for each of [Back 1st] to [Back 3rd].

The following shows the setting conditions that can be set in the 
multistream settings.

Installing a barcode module (optional) allows you to scan barcodes in 
the document. Click the [Barcode] button on the [Others] tab to 
configure barcode scanning conditions.
See Help for details about settings.
