[Check overlapping] and [Check length difference], both parameters will be used
for monitoring the fed documents.
When checking the document length, select the length difference for which a Mul-
tifeed will be detected. Select 10/15/20mm. If the detected document length is
smaller than the selected size, it will be recognized as a Multifeed.
• When scanning documents of different length together in the same stack,
select [Checking overlapping]
• If something is glued to the documents (stamps, memo or photos), they will
be recognized as Multifeed when using [Checking overlapping]
scanning such documents, use [Checking length difference] instead.
However, when using the [detection area/none-detection area] function,
you can also use [Checking overlapping]
• The setting above can be done as well on the scanner driver configuration
window.
(In this case, the scanner driver selection will have priority)
