General The heater lamp control circuit detects the heat roller surface temperature from the thermistor, and converts it into a voltage level, which is delivered to the CPU analog input pin. The CPU converts the analog voltage into a digital signal level, com- pares it with the set value of simulation, and turn on/off the heater lamp depending on the level, maintaining the heat roller surface temperature at a constant level.

It is impossible for the control signal of each load from the CPU to directly drive the load. The control signal is passed through the driver A: Stepping motor phase A coil drive signal IC then to each load.

- Page 88 www.freeservicemanuals.info 1/11/16 (12) Main motor drive circuit The encoder signal for the main motor is inputted to the CPU, where operation process is performed. Then the CPU delivers the PWM signal to control the main motor. The PWM signal (MM-PWM) from the CPU is applied to the gate of FETQ103 through the driver IC104 and transistor Q214, flowing a current through the main motor.

The STR-F6515 block diagram across-the-line capacitor, the line bypass capacitor, and the common mode choke coil are provided on the AC PWB.
- Page 91 www.freeservicemanuals.info 1/11/16 When the output voltage falls below the specified level under overload state, the voltage in the additional winding of the primary side also falls accordingly to fall the VIN pin voltage below the operation start voltage. Therefore, the VIN pin voltage rises again and starts operation at the operation start voltage, performing intermittent operations.
