3 Select a detection method.
Method Description
None Does not detect multifeeds.
Check
Overlapping
(Ultrasonic)
Detects multifeed by the overlapping of
documents.
When this is selected, you can also specify the
two following options:
z Specify the detection range by the length from
the leading edge of the document.
Proceed to "Method of Multifeed Detection
[Multifeed]" (page 145) for more details.
z Ignore the multifeed when there is paper of the
same size attached to a designated location
on the page.
Proceed to "Ignoring Multifeed for a Set
Pattern" (page 82) for more details.
Check Length Detects multifeed by the difference in length of the
documents.
Note that multifeeds cannot be detected
accurately when scanning a mixed batch of
different sizes.
Check
Overlapping
and Length
Detects multifeed by the combination of [Check
Overlapping (Ultrasonic)] and [Check Length].
Note that multifeeds cannot be detected
accurately when scanning a mixed batch of
different sizes.
Length Select a length difference from 10/15/20 mm.
Any length under the specified value will not be
detected as multifeed.
z To scan documents with different lengths, specify
[Check Overlapping (Ultrasonic)].
z When a photo 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 be used if you restrict the detection range.
z Multifeed 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.
