M1 Control
M1 is controlled by the following output signals. M1 speed is detected by the pulse
disk mounted on the motor output shaft and Document Feed Motor Pulse Sensor
(M1 CLK). M1 pulses are applied to IC1A-74, and period A is maintained at the
same length so that the motor rotates at a constant speed.
