The duplexing driver PCB monitors the status of the top of page sensor (SR710) sent from the DC controller and controls the duplexing reverse motor (M11) and
the duplexing flapper solenoid (SL10) in order to reverse the paper.
1) The duplexing driver PCB rotates the duplexing reverse motor clockwise after Approx. 2.5 seconds from when the top of page sensor detected the leading edge
of first side of paper. Then after Approx. 0.25 second, it turns ON the duplexing flapper solenoid to make a paper path to the duplexing reverse unit.

2) The duplexing driver PCB turns OFF the duplexing flapper solenoid after Approx. 2.5 seconds from when the trailing edge of first side of paper passed through
the top of page sensor.
Accordingly a paper path to the duplexing feed unit is made. At the same timing, it rotates the duplexing reverse motor counter clockwise.
