The Multi-Feed Detection Tab
Multi-Feed Detection
Multi-Feed Detection allows you to detect overlapped document that go through the auto
document feeder. Multi-Feed usually occurs due to stapled documents, adhesives on
documents, or electro-statically charged document. Note
：
The availability of the function
varies based on type of scanner.
Additional Length Detection
Additional Length Detection allows you to define the length of document being multi-fed.
This value indicates the additional length exceeding your scan area. The Display window will
show the size of the document as you change the value. A value of 0 indicates no additional
length detection. The Additional Length Detection is best used when scanning same-size
documents in the auto document feeder.
Ultrasonic Detection
Ultrasonic Detection allows you to set overlapped document by detecting paper thickness
between documents. Note
：
The availability of the function varies based on type of scanner.
There are two options available if Multi-Feed is detected.
Stop Scanning after Multi-Feed
If this is selected, the scanner will stop the feeder and prompt a multi-feed warning
message. In addition, the multi-feed paper will be ejected from the scanner
automatically.
Note: The availability of the [
Auto Clear Multi-Feed Paper
] feature varies based
on scanner type. If your scanner does not support this feature, remove the multi-
feed paper manually.
If this is not selected, the scanner will continue scanning the entire document
though multi-feed is detected. After the entire document has been scanned, a multi-
feed dialog box will be prompted to indicate the page number which has been
detected multi-feed and need to be rescanned.
