Duplex reverse and duplex feed control
The duplex reverse control reverses the paper after the first side is printed and feeds it to the duplex re-
pickup position to print the second side of the page.
1. At a specified time after the first side of a page is printed, the duplex reverse motor rotates, and the
duplex reverse solenoid is turned on.
2. The duplex flapper moves, and the paper is fed to the duplex reverse unit.
3. After a specified period of time, the duplex reverse motor is reversed, and the paper is fed to the duplex
feed unit.
4. The duplex reverse motor and the pickup motor move the paper to the duplex re-pickup position.
5. The duplex reverse motor and the duplex feed clutch stop, and the paper feed operation pauses.
6. After a specified period of time, the duplex reverse motor rotates, and the duplex feed clutch is turned
on. The paper is then picked up again.
