Duplex Unit

■ Basic Operation

1) The Reverse Upper Flapper Solenoid (SL5) is turned OFF to switch the feeding path to the
Reverse Assembly side.
2) When the paper's trailing edge passes through the Fixing Roller, rotating speed of the
Reverse Motor (M14) is increased (duplex pull-in speed) to make the paper stopped at the
duplex reverse position.
3) The Reverse Motor is driven by the duplex pull-in speed to feed the paper to the Duplex
Assembly (the flapper feeds the paper to the Duplex Assembly). Then, the Duplex Left
Sensor (P66) detects the paper's leading edge, and the paper is fed for a specified distance
to stop at the position of Duplex Left Roller.
