4.5.1 Setting the Multifeed Detection Method
"Multifeed" is an error that occurs when two or more sheets are fed simultaneously into
the ADF. The detection of the difference in length is also regarded as multifeed.
By default, multifeed detection monitors for paper overlaps in the central column (25 mm
either side from the center of the document) of the document being scanned.
Setting the multifeed detection zone
If stickies, slips, photos, or other paper ("attached paper" from here on) are
attached on the documents, this section is considered to be an overlap causing
unnecessary detection as multifeed. When scanning those documents, you can
adjust the multifeed detection area to ignore a specific area with attachments such
as photos and prevent mis-detections.
Setting the intelligent multifeed detection
The "intelligent multifeed detection" allows the length and position of the attached
paper to be memorized in the scanner so that the multifeed will not be detected
from the next scan.
Setting the function for scanning at a high altitude
Low atmospheric pressure at a high altitude may decrease the level of accuracy of
the ultrasonic sensor to detect multifeeds.
The "high altitude mode" allows the scanner to be used at a high altitude of 2,000
m or more.
For document requirements for multifeed detection, refer to "A.5 Multifeed Detection
Conditions" (page 405).
1. Select [Multifeed Settings] under [Scanner Settings].
