Detecting Multifeed Errors
Multifeed is an error where two or more sheets are fed through 
the ADF at once. It is also called a multifeed when a different 
document length is detected. 
You can have an error message appear when a multifeed 
occurs.
Settings for multifeed detection can be configured in the 
scanner driver or the Software Operation Panel.

detected lengths.
Note that multifeeds cannot be detected 
accurately when scanning a mixed batch of 
different sizes.
