When this is selected, you can specify the following two options:
● Specify an area to detect overlapped documents by the length from the leading edge of the document
in the feeding direction.
For details, refer to Specifying the Area to Detect Overlapped Documents [Document check area
specification for Multifeed Detection] (page 185).
● When a piece of paper is attached on a document, the length and position of the paper can be
memorized, and set to ignore overlapping of documents.
For details, refer to Configuring Not to Detect Certain Overlap Patterns (page 80).
Check Length
Detects overlapped documents according to the difference in length.
Select this to scan documents of the same length.
Note that overlapped documents cannot be detected accurately when a mixed batch of different lengths
are scanned.
Check Overlapping and Length
Detects overlapped documents by the combination of [Check Overlapping(Ultrasonic)] and [Check
Length].
When this is selected, you can specify the following two options:
● Specify an area to detect overlapped documents by the length from the leading edge of the document
in the feeding direction.
For details, refer to Specifying the Area to Detect Overlapped Documents [Document check area
specification for Multifeed Detection] (page 185).

Note that overlapped documents cannot be detected accurately when a mixed batch of different length
are scanned.
Length
Specify the difference in length of documents to be detected as overlapped documents.
Overlapped documents are detected when the the difference in length of documents is longer than the
specified value.
Specify this item when [Check Length] or [Check Overlapping and Length] is selected.
Any length under the specified value is tolerated as a slight error and not detected as overlapped
documents.
Select from 10/15/20 mm. The factory default setting is "10".
ATTENTION
● To scan documents with different lengths, select [Check Overlapping(Ultrasonic)].
● When an attachment such as a sticky note, receipt, or photo is attached on the document, the
attachment part of the document may be detected as overlapping of documents if [Check
Overlapping(Ultrasonic)] is selected. In that case, select [Check Length].
