2 ] Scanning Mode (Solenoid: Off, Motor Rotation: Reverse) - Brother FAX255 Service Manual

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

Just as in the recording mode, the control electronics deactivates the solenoid in the scan-
ning mode to lock arm A.
The motor rotates in the reverse direction and the sun gear 18/82 (B) rotates clockwise so
that the planet gear 20B (C1) transmits the rotation to the separation roller gear (L) and white
pressure roller gear (O) via the several gears.
