If the page is to be duplexed, the fuser output drive roll continues to pull the media until it clears the paper exit
flag and then reverses the rotation of the roller in order to pull the media back into the printer duplex assembly.
The media is then routed down through the duplex path until it reaches the bump aligner roll. Once in this
position, it enters the EP path for the second time.

Paper exit flag
The paper exit flag serves two purposes. When it triggers the paper exit sensor, it serves as a one-way gate for
the media when it is exiting the printer to the output bin and also serves as a one-way gate when the media is
entering back into the printer for a duplex print. In other words, it diverts the print media's path, directing it to
either the output bin or the duplex paper path.
