zWhen a photograph or a piece of paper is attached on the document, the overlapping part of the document may be falsely detected as multifeed if [Check Overlapping (Ultrasonic)] is specified. In that case, specify [Check Length].
Note however that [Check Overlapping (Ultrasonic)] can still be used by restricting the detection range.
zMultifeed cannot be detected when using the Carrier Sheet.
This setting can also be configured from the scanner driver's setup dialog box. Note that priority is given to the scanner driver setting.
