Detection Description
Proceed to Specifying the Area to Detect Multifeed
[Document check area specification for Multifeed
Detection] (page 255)
for more details.
●
Ignore the multifeed when there is paper of the
same size attached to a designated location on the
page.
Proceed to
Bypassing Multifeed Detection for a
Fixed Format (page 111) for more details.
Check Length Detects multifeed by the difference in length of the
documents.
Note that multifeed cannot be detected accurately
when scanning a mixed batch (in different sizes) or a
Job Separation Sheet.
Check Overlapping and Length Detects multifeed by a combination of [Check
Overlapping (Ultrasonic)] and [Check Length].
Note that multifeed cannot be detected accurately
when scanning a mixed batch (in different sizes) or a
Job Separation Sheet.
Length Select a length difference from 10/15/20 mm. Any
length under the specified length will not be
detected as multifeed.
ATTENTION
●
To scan documents with different lengths, specify [Check Overlapping (Ultrasonic)].
●
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 this case, specify
[Check Length].
Note however that [Check Overlapping (Ultrasonic)] can still be used by restricting the detection range.
HINT
This setting can also be configured in the scanner driver's setup dialog box. Note that priority is given to
the scanner driver setting.
