Abstract
An automatic document feeder is operable in a simplex, or one-sided, reproduction mode and a duplex, or two-sided, reproduction mode. In the duplex mode, the original document sheets are transported through the feed path only twice and output in the same relative page order in which the sheets were input. By this, 100% productivity can be achieved. The feeder assembly uses two separate feeders, one simplex top feeder and one duplex top feeder, to obtain two pass operation. Alternatively, a single feeder is used that can feed from both the top of the stack or from the bottom of the stack depending on the mode of reproduction. A controller allows selection between the simplex and duplex modes and controls the feeding assembly based on the selection.
