3.4 Transfer Belt & Fuser
3.4.1 Major functions
Belt feeds the paper to the direction of FUSER
• SENSOR ADC
SENSOR ADC reads the toner patch on the BELT, and converts it to voltage value. Voltage value
is used to control the density of toner.
The FUSER fixes toner which was transferred onto the paper but not fixed by the heat and pressure
and feeds paper before and after being fixed.
The FUSER mainly consists of the following parts:
• Heat Roll
• Heater Lamp
• Temp. Sensor
