fed through the ADF at once. It is also called a “multifeed”

 

 

 

 

when a difference in document length is detected.

 

 

 

 

You can set the scanner to detect multifeeds and display an

 

 

 

 

error message.

 

 

 

 

Also, a window in which you can check the multifeed images

 

 

 

 

can be displayed.

 

 

 

 

Settings for multifeed detection can be configured in the

 

 

 

 

scanner driver or the Software Operation Panel.

 

 

 

 

For information on how to configure by the Software Operation
