2. Controlling the Temperature of the Fixing Heater
The fixing heater is turned OFF during standby. To prevent fixing faults caused by low temperature,
either of the following five types of temperature control is executed depending on the temperature of the
fixing heater (output of the main thermistor TH1) at power-on and the count of copies to be made.
a. If the temperature at copy start is less than 100°C, either of further five types of control is chosen
depending on the count of copies: q 235° to 190°C, w 225° to 180°C, e 215° to 180°C, r 250° to
180°, and t 195° to 180°C. Normally, one of w through r is sleeted.
