Duplex reverse and duplex feed control
The duplex reverse control reverses the paper after the first side is printed. The duplex feed control feeds the
paper to the duplex block to print the second side of the page.
The operational sequence of the duplex reverse and duplex feed control is as follows:
1. The DC controller rotates the duplex reverse motor and drives the duplex reverse solenoid at a specified
timing after the first side of page is printed.
2. The duplex flapper moves and the paper is fed by the duplex reverse roller.
3. The duplex reverse motor is reversed.
4. The duplex reverse roller is reversed accordingly the paper is switched back.
