If the overlap pattern is memorized, documents with the same overlap pattern are
not detected as overlapped documents from the next scan.
Scanning will stop after the detected overlapped documents are scanned to the
bottom edge.
In this operation mode, up to four overlap patterns can be memorized at a time
(when one sheet is scanned), and up to 32 overlap patterns can be memorized in
total.
When the 33rd overlap pattern is detected, the first pattern that was memorized is
overwritten.
However, when the scanner is turned off and on, the number of memorized overlap
patterns depends on the setting for [When powering off] of [Memorize overlap
pattern].
Automatically Bypass (length)
Specify whether the length of the longest piece of paper attached on a document
detected as overlapped documents is memorized as an overlap pattern.
If the overlap pattern is memorized, a document with a piece of paper in the same
length or shorter attached is not detected as overlapped documents from the next
scan.
Scanning will stop after the detected overlapped documents are scanned to the
bottom edge.
Only one overlap pattern can be memorized in this operation mode.
Memorize overlap pattern
When confirming image
When [Automatically Bypass (combination of length and position)] or [Automatically
Bypass (length)] is selected, you can manually switch whether or not to memorize an
overlap pattern on the touch screen when overlapped documents are detected.
Select this to on to change the default setting to enable in order to memorize the
overlap pattern when overlapped documents are detected.
The factory default setting is set to off.
The overlap pattern is memorized when the [Scan] button on the scanner is pressed
for the next scan.
For details about the function that memorizes an overlap pattern, refer to
Configuring Not to Detect Certain Overlap Patterns (page
When powering off
Specify whether or not to keep overlap patterns upon turning the power off.
When this is set to on, eight of the most recent overlap patterns for [Automatically
Bypass (combination of length and position)] and one overlap pattern for
[Automatically Bypass (length)] can be used the next time the scanner is powered on.
The factory default setting is set to off.
