3 ] Copying Mode (Solenoid: On Off, Motor Rotation: Forward) - Brother FAX218 Service Manual

[ 3 ] Copying mode (Solenoid: ON OFF, Motor rotation: Forward)
The control electronics at first activates the solenoid to release the stopper of arm A from the
cutout X of the clutch arm while rotating the motor in the forward direction. Accordingly, the
sun gear 18/82 (B) rotates counterclockwise so that both the planet gears 20B (C1) and 20A
(C2) transmit the rotation; C1 rotation to the platen gear (H) and C2 rotation to the separation
roller gear (L) and white pressure roller gear (O).
Once the planet gear 20A (C2) becomes engaged with gear K, the control electronics deacti-
vates the solenoid.
