(1) LGC board provides a signal to control the rotation of the developer motor.
(DVMON: Developer motor ON signal)
When signal from LGC board is the level "L", the developer motor stops.
(2) DVMCW signal controls the rotational direction of the motor. The motor rotates forward (CCW) but
does not rotate backward (CW) in actual movement. Namely, DVMCW signal is always output level
"H".
