The [Feeding] tab sheet provides settings for different feeding 
options. Options such as double feed detection and staple 
detection can be set. 

This function stops document transport when double 
feeding of document pages is detected, and enables you to 
select the detection method to suit the type of documents 
to be scanned. 

[Detect by Length]
This method of double feed detection is useful for batch 
scanning of same-size documents. The length of the first 
document page fed is measured as a standard, and if a 
subsequent document is detected to be 35 mm (1.4") 
longer (or shorter) than the standard, a double feed is 
judged to have occurred, and document transport is 
stopped.

[Detect by Ultrasonic]
This method of double feed detection is useful for batch 
scanning of different-size documents. When the ultrasonic 
sensor detects overlapping documents and spacing 
between documents, a double feed is judged to have 
occurred, and document transport is stopped. 

Both detection methods can be used together. 

■ Staple Detection

When sensors at both sides of the feed inlet detect the bent 
corner of a stapled document, an error message appears 
and feeding stops.

• Staple detection detects the bent corner that occurs when one 

of the four corners of a document has been stapled. 

• Staple detection may not operate properly in the following 

cases where bending does not occur in documents.
– The document is stapled at two or more corners.
– The document is size smaller than STMT/A5.
– The position of the left or right document guide has been 

changed, and the document has been shifted to the left or 
right side.
