Drive

The duplex motor [B] feeds out paper to the output tray in single-sided mode and also feeds paper to the duplex path in duplex mode. When a sheet of paper is detected by the paper exit sensor [C] in duplex mode, the duplex motor stops and rotates in reverse. The paper exit roller [A] feeds the sheet of paper to the duplex path. The duplex transport roller [D], which is driven by the duplex motor through the timing belt, transports the sheet of paper to the registration roller.
