Settings Related to the Detection for Overlapped Documents (Multifeed)
Specifying a Method to Detect Overlapped Documents [Multifeed]
Multifeed is an error that occurs when two or more sheets are overlapped and fed at once.
Configure the settings to detect overlapped documents during a scan.
Overlapped documents are detected with the ultrasonic sensor or according to the difference in length
of the documents.
When overlapped documents are detected, an error message is displayed and the scan stops. If
documents are overlapped within 30 mm from the leading edge, they are not detected as overlapped.
ATTENTION
When the feed mode of the scanner is set to [Manual - Single], document overlapping will not be
detected.
Manual Single Mode is the mode for scanning a document folded in half or a multi-layered
document such as an envelope. Therefore, even if the setting for detecting overlapped documents is
enabled, such documents are not detected as overlapped documents.
1 Start up the Software Operation Panel.
For details, refer to
Starting Up the Software Operation Panel (page 303) .
2 From the list, select [Device Setting 2] → [Multifeed].
3 Select a detection method.
None
Does not detect overlapped documents.
This is the factory default setting.
Check Overlapping(Ultrasonic)
Detects overlapped documents with the ultrasonic sensor.
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 340) .
● 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 126) .
Check Length
Detects overlapped documents according to the difference in length.
Select this to scan documents of the same length.
