[ 1 ] Scanning mode (Solenoid: OFF, Motor rotation: Reverse)
In the scanning mode, the control electronics deactivates the solenoid. When the motor ro-
tates in the reverse direction, the clutch lever turns counterclockwise with the spring so that
its cutout x becomes engaged with the stopper of arm A. Once arm A is locked, the planet
gear 20A ("L") will not be engaged with any other gear but simply idle.
The motor's rotational torque turns the sun gear 20/90 ("B") clockwise so that the planet gear
20B ("C") transmits the torque to the separation roller gear ("F"), white pressure roller gear
("I") and document ejection roller gear ("K") via the several gears.
