Duplex Tray Feed Mechanism
Duplex inverter solenoid: Moves the junction gate, directs the paper
down to the duplex tray
Duplex transport rollers: Feed the paper into, through, and out of the
duplex tray
In duplex mode, the junction gate switches and the inverter feeds the paper down
into the duplex unit instead of back up to the machine.
