CHAPTER 7 FIXING SYSTEM
2.4 Protective Mechanism
The machine is equipped with the following protective mechanisms used to prevent malfunction of the fixing heater: 1.Thermistor High Temperature The ASIC and the high temperature detection circuit on the DC controller monitor the voltage readings of the main thermistor and sub thermistor; if the main thermistor detects a voltage equivalent of the following temperature, the CPU will identify the condition as indicating overheating. � 220°C or higher (read by main thermistor TH101) 2. Thermistor Disconnection The connector detection circuit on the DC controller PCB monitors the THCNCT signal, and the CPU will assume that the connector of the thermistor is disconnected if the signal is �0�. 3. Cutting Off the Power in Response to Overheating (as detected by the thermal switch) If the internal temperature of the thermal switch (THSW101) exceeds about 230°C, the thermal switch will go OFF to cut the power to the fixing heater. 4. Detecting the Activation of the Fixing Heater The fixing heater detection circuit on the power supply PCB causes the HEATDT* signal to go �0� if the FSRDRV* signal is �0� (fixing heater ON). As such, the ASIC will assume that the fixing heater activation is faulty (triac short circuit) if the HEATDT* signal goes �1�.
