Setting Multi-feed detection Multi-feed Detection aids in document processing by detecting
documents that may go through the feeder overlapped. Multi-feeds can
happen due to stapled documents, adhesives on documents, or
electrostatically charged documents. 3D Multi-feed Detection combines
ultrasonics (amplitude and phase) with physical length detection to
virtually eliminate the chance of loosing data due to multi-feeds.
The Ultrasonic Sensor is located in the center of the transport (behind
the feeder module). In order for multi-feed documents to be detected
correctly, they must pass under this sensor.
Length Detection this option can be enabled or disabled. The
default is disabled. If Length Detection is enabled, enter the maximum
length (in inches). This is the minimum length of the document that can
be scanned with a multi-feed being detected. Length detection is used
when scanning same-sized documents to check for overlap. For
example, if you are scanning 8 ½ x 11” documents in portrait mode, you
may want to enter a value of 11.25 in the Maximum Length field. The
maximum value is 30.5 inches.
Auto Set when enabled, will automatically set the maximum length
value to .50-inch greater than the length of the currently selected page
size.
Units length detection will be displayed in inches. Pixels and
Centimeters are not available through the graphical user interface.
Stop Scanner if this option is not selected, the scanner will display
and log the condition but continue to operate. If selected, the scanner
will display, log the condition and stop the feeder (the scanner will
remain enabled). When an overlap or multi-feed is detected, the
scanner stops the feeder, clears the transport of all pages and then the
documents can be refed.
End Job if this option is selected, the scanner will display, log the
condition and stop the feeder and transport (the scanner will be
disabled). Scanning can only be resumed when the scanner is
re-enabled from the host.
