Detecting Multifeed Errors
Multifeed is an error when two or more sheets overlap and are
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
Panel, refer to

Condition
Description
None
Does not detect multifeed.
Panel setting
Enables the setting of the Software
Operation Panel.
Check Overlapping
(Ultrasonic)
Uses the ultrasonic sensors inside the ADF
to monitor the documents during feeding
and to identify multifeeds according to the
deviation of the reflected ultrasonic waves.
Check Length
Monitors the document length during
feeding, and identifies multifeeds according
to the deviation of detected lengths. Note
that multifeed cannot be detected
accurately when scanning a mixed batch (of
different sizes) or a Job Separation Sheet.
Check Overlapping
and Length
Monitors both document overlapping and
length to detect multifeeds.
Note that multifeed cannot be detected
accurately when scanning a mixed batch (in
different sizes) or a Job Separation Sheet.
