Feeding control for an image reproduction apparatus operable in simplex and duplex reproduction modes

A method of feeding a stack of original document sheets through an image reproduction apparatus, comprising:

• placing a stack of original document sheets in a feeder in an established page order;
• selecting one of a simplex reproduction mode and a duplex reproduction mode;
• feeding each of the sheets through a feed path including an image reproduction station, wherein the sheets are fed through the feed path once in the simplex mode and twice in the duplex mode;
• and
• outputting the stack of original document sheets with each sheet stacked on top of a previously output sheet in the same relative page order;
• wherein feeding each sheet through the feed path comprises driving a discharge transport in one direction to output the sheets and a second direction to feed the sheets back through the feed path.

An image reproduction device operable in at least a simplex reproduction mode and a duplex reproduction mode, comprising:

• a feeder assembly that supports a stack of original document sheets in an established page order;
• an image reproduction station that creates an image based on each sheet of the original document;
• a sheet transport with a feed path that transports each original document sheet through the feed path from the feeder assembly past the image reproduction station;
• an output that receives the stack of original document sheets with each successive sheet stacking on top of a previously output sheet in the same relative page order from the sheet transport;
• and
• a controller connected to the sheet transport that operates in a simplex mode in which each original document sheet passes through the feed path only once and a duplex mode in which each original document sheet passes through the feed path only twice,
• wherein the simplex feeder and the duplex feeder are located at opposite sides of the document transporter.

A method of feeding a stack of original document sheets through an image reproduction apparatus, comprising:

• placing a stack of original document sheets in a feeder in an established page order wherein a simplex feeder and a duplex feeder are located at opposite sides of the image reproduction apparatus;
• selecting one of a simplex reproduction mode and a duplex reproduction mode;
• feeding each of the sheets through a feed path including an image reproduction station, wherein the sheets are fed through the feed path once in the simplex mode and twice in the duplex mode;
• and
• outputting the stack of original document sheets with each sheet stacked on top of a previously output sheet in the same relative page order.
