♦ Multifeed Detection
This option detects a multifeed (occurs when two or more documents are sent) based on the
set condition.
If a multifeed is detected when this setting has been turned on, the device will stop and an
error message output.
However, when [Double-page spread], [Cropping (Front)] or [Cropping (Duplex)] is
selected, an error message will appear when a multifeed is detected but the device will not
stop.
None
Multifeed detection is not performed.
Hardware Setting
A multifeed is detected based on the device setting.
Check thickness
The thickness of the transmitted document is checked by the sensor in the device.
A multifeed is detected by detecting changes in the thickness when more than one
document is sent.
Check length
The length of the transmitted document is checked by the sensor in the device.
A multifeed is detected by detecting changes in the length when more than one
document is sent.
Check thickness and length
The thickness and length of the transmitted document are checked.
Check overlapping
The overlapping of the transmitted document is checked by the sensor in the device.
A multifeed is detected by overlapping when more than one document is sent.
Check overlapping and length
The overlapping and length of the transmitted document are checked.
For example, the detection accuracy can be improved by using [Check thickness] or [Check
overlapping] for continuous scanning of forms that have different lengths and [Check
length] for scanning of forms that have different thicknesses.
Depending on scanner model, the selectable items are different. Refer to “Relevant Image
Scanner Specification” of Appendix.
