3 Select a detection method.
Method Description
None Does not detect multifeed.
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 top of the document.
Proceed to "Specifying the Area to Detect
Multifeed [Document check area specification
for Multifeed Detection]" (page 182) 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 105) 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.
When this is selected, you can also specify the
two following options:
z Specify the detection range by the length from
the top of the document.
Proceed to "Specifying the Area to Detect
Multifeed [Document check area specification
for Multifeed Detection]" (page 182) 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 105) for more details.
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 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.
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.
