The following figure illustrates the duplex (two-sided output) paper path of a printer with a dual stacker and a standard feeder. Materials may originate in either feeder tray 1 or feeder tray 2. The duplex paper tray receives the materials before they go through a second time to receive the second image. As the pages move through for the second image, they follow the simplex path. The pages are then stacked in either stacker tray 1 or stacker tray 2, depending on your selection at the beginning of the job.

When you add a high-capacity feeder to your system, only the beginning of the paper path changes, which is the source of paper supply.
