3-17 System Overview Guide
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.
