Definition of SEF and LEF
SEF (short edge feed) refers to the shorter edge of a document as
the first edge to contact the Document Feeder rolls; for example,
the 8.5 inch side of an 8.5 x 11 inch document.
LEF (long edge feed) refers to the longer edge of a document as
the first edge to contact the Document Feeder rolls; for example,
the 11 inch side of an 8.5 x 11 inch document.
The page feed and orientation controls are only used to describe
to the scanner how the original image has been loaded into the
document feeder. They have no bearing on how your image is
oriented (landscape or portrait) when printed.
The SEF/LEF toggle buttons and the Rotate A button (Advanced
Scanning) have no relationship to final image orientation. When
properly set, they simply ensure that when previewing, your image
appears upright in the Preview window.
NOTE: When scanning large numbers of documents from the
Document Feeder, arrange them LEF to achieve faster throughput
speed.
