The Drum Motor is a clock-controlled multispeed device which can operate at three different
speeds, as shown in Table 2. Also like the Main Motor, the Photoreceptor Motor is controlled by
the IOT CPU PWBA and IOT Drive PWBA. The Photoreceptor Motor includes two additional
connections: BRAKE ON and ENC A. Figure 1 shows the control and power lines going to the
Drum Motor, and Figure 2 shows the motor’s location.
