The drive of the CR motor is transmitted to the CR unit via the CR timing belt. And, the CR home position is detected with the HP PE sensor. This sensor is available as the CR home position sensor while the CR motor operates in each sequence. The function of this sensor varies depending on the running condition of the motors. It is available as the PE sensor when the PF motor operates in each sequence. When the detection plate molded on the CR unit pushes down the HP detection lever and the CR...

Regardless of the state of the power switch On or OFF , the voltage is always applied to the primary side of the power supply board from the moment or at the state that AC-plug is plugged in. At this time, F1 plays a role of preventing AC100V from coming into the F1. L1 also prevents high harmonic wave noise generated in the RC circuit filter which consists of C1 from going out, and eliminates the noise from outside here. The AC is full-wave rectified by the diode bridge DB1, and converted to x...
