Specifying a Multifeed Detection Method [Multifeed]
Multifeed is an error when two or more sheets are fed through the ADF at once. It is also called a
"multifeed" when a different document length is detected.
Not noticing multifeed errors while scanning may put you in a situation where important data are

Multifeed detection function is equipped to prevent such troubles. When this function is enabled, an
