3.34 Detect Double Feed
This function detects the feeding of more than one sheet of the document at a time.
If a double feed is detected, you can select to beep or stop the scan.
IMPORTANT NOTES:
•
With this function, ultrasonic waves are aimed at the document to detect double
feed by the level at which the waves pass through the sheets. The function can
detect double feed even when sheets are superimposed exactly on top of each
other, but it may not be detected properly with some paper thicknesses and when
creasing and other factors are present.
•
When important documents are to be scanned, check the number of document
sheets and the number of scanned image sheets.
•
When scanning a document containing paper in different sizes, double feed can be
detected when this function is left at on.
