Multifeed Detection - Fujitsu ScanSnap N1800 Operator's Manual

6.9.19 Multifeed Detection

"Multifeed" is an error that occurs when two or more sheets are fed simultaneously into
the ADF. The scanner can be set to detect multifeeds and stop the scan with an error
message.
Multifeeds are to be detected by layer and length. The following explains how to set
whether or not multifeeds are to be detected, and setup multifeed detection method.
For multifeed requirements, refer to
1. On the [Scan Settings] window, select the [Advanced] tab.
2. Press the [Multifeed Setup] button.
The [Multifeed Setup] window appears.
3. If multifeeds are to be detected, select which detection method is to be
used.
ATTENTION
An error will occur if the [Length] or [Both] multifeed setting is used with the [Auto]
paper size, and the document bundle being scanned contains different size pages.
When a multifeed is detected with [Ultrasonic], you can choose to ignore the multifeed
and continue scanning by pressing the [Retry] button on the error message window.
This returns you to the [Scan Settings] window. The selected setting is displayed
to the right of the [Multifeed Setup] button.
