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
LEF SEF 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.
