Detection
Description
●
Specify the detection range by the length
from the leading edge of the document.
Proceed to
Multifeed [Document check area
specification for Multifeed Detection] (page
266)
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
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.
