Registration motor control circuit
The registration motor (M19) is a stepping motor driven by the control signal output from the engine
CPU on the LGC board and rotates the registration roller.
The registration motor is driven by the pulse signal (RGTMA, RGTMB, RGTMC, RGTMD) output from
the motor driver. These pulse signals are formed based on the reference clock (RGMCK) and output
only when the enable signal (RGMEN) is a high level. Also, the rotation speed or direction of the motor
can be switched by changing the output timing of each pulse signal.
