3)Driving the fuser unit The rotation of the main motor is transmitted to the heat roller gear via some
� gears. � The paper exit sensor lever detects the paper exiting the fuser unit.
4)Fusing the temperature
� Sequence
a)When turning ON the power, the heat roller is heated up by the heater lamp. b)When the heat roller reaches a specific temperature (302°F/150°C), the main motor is turned ON and the heat roller and the pressure roller start rotating. When the heat roller reaches the proper fusing temperature (378°F/192°C), the main motor is turned OFF and the unit is ready. c) The thermistor detects the heat roller temperature and controls switching the fuser lamp to keep the temperature constant.
�
NOTE: E4-01 will be indicated if the heat roller temperature is not reach within the specified period of time after the power is turned ON.
