Abstract
In an output sheet handling system for a reproduction apparatus, for selective stacking of the output sheets into at least one stacking tray, with a sheet ejection system for gripping and ejection of the output of the printed sheets into a stacking tray sequentially as individual output sheets or as a compiled stack of sheets, the sheet ejection system includes an automatic variable normal force system automatically providing a substantially higher gripping normal force for ejection of a compiled stack of sheets than for ejection of individual output sheets. The ejection system preferably increases the gripping normal force for the set ejection in proportion to the thickness of the compiled stack being ejected, and feeds individual delicate sheets through a nip with an automatically substantially lower normal force.
