2 ] Scanning Mode (Solenoid: Off, Motor Rotation: Reverse) - Brother FAX100 Service Manual

[ 2 ] Scanning mode (Solenoid: OFF, Motor rotation: Reverse)

Just as in the recording mode, the control system deactivates the clutch solenoid in the
scanning mode to lock arm A.
The motor rotates in the reverse direction and the sun gear 18/73 (B) rotates clockwise so
that the planet gear 20A (C2) transmits the rotation to the separation roller gear (L) and LF
roller gear (O) via the several gears.

[ 3 ] Copying mode (Solenoid: ON
The control system at first activates the clutch solenoid to release the stopper of arm A from
coutout X of the clutch lever while rotating the motor in the forward direction. Accordingly,
the sun gear 18/73 (B) rotates counterclockwise so that both the planet gears 20B (C1) and
20A (C2) transmit the rotation to the platen gear (E) and the roller gears (separation roller
gear and LF roller gear), respectively.
Once the planet gear 20A becomes engaged with the gear P, the control system deactivates
the clutch solenoid.
