[Feeding] Tab Sheet

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

Double Feed Detection

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.

Hint

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.

IMPORTANT

•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. (See “Adjusting the Document Guides” on p. 3-7.)
