After the machine completes the 1st print and the paper's trailing edge passes over the delivery sensor (PS803), the duplexing drive solenoid (SL2) is turned on and

the drive of the main motor (M1) is transmitted to the delivery roller and the duplexing feed roller.

By turning the delivery roller in reverse direction, the paper is lead to the duplexing feed unit, and sent to the feed roller via duplexing feed roller.

There is no sensor on the duplexing paper's feeding path to detect the arrival/passage of paper.

There is no stationary function to stop and retain paper in duplexing unit.
