[ 1 ] Scanning mode (Solenoid: OFF, Motor rotation: Reverse) In the scanning mode, the control electronics deactivates the solenoid. When the motor rotates in the reverse direction, the clutch lever turns counterclockwise with the compression spring so that its cutout becomes engaged with the stopper of arm A. Once arm A is locked, planet gear 34A ("J") will not be engaged with any other gear but simply idle. The motor's rotational torque turns sun gear 24/90 ("B") clockwise so that planet gear 34B ("C") transmits the torque via gear "D" to gear "E" which drives the separation roller gear ("G") and gear "F." As gear "F" rotates, the LF roller gear ("I") and document ejection roller gear ("H") also rotate. Arm A Locked by Cutout of Clutch Lever Active Gears III - 8

Scanning mode (Solenoid: OFF, Motor rotation: Reverse)
In the scanning mode, the control electronics deactivates the solenoid.
When the motor rotates in
the reverse direction, the clutch lever turns counterclockwise with the compression spring so that its
cutout
becomes engaged with the stopper of arm A.
Once arm A is locked, planet gear 34A
("J") will not be engaged with any other gear but simply idle.
The motor's rotational torque turns sun gear 24/90 ("B") clockwise so that planet gear 34B ("C")
transmits the torque via gear "D" to gear "E" which drives the separation roller gear ("G") and gear
"F."
As gear "F" rotates, the LF roller gear ("I") and document ejection roller gear ("H") also rotate.
