2.1.1.6 Fusing

Fusing is the process of fixing the toner image transferred from the image transfer process on the
paper. This time, we have used the heating roller method for fusing. The heating roller method is
the process of fixing the toner image using the heat roll that is heated by the heater assy.
When switch on the power, the heater assembly lights up until the temperature of the heat roll
becomes 147 degrees C. After the warm up, the MC PWB (Main Control Unit Printed Wiring
Board: engine controller board) controls the on/off operation of the heater, according to
signals from the thermistor.
