Fuser control
Fuser control method
The on/off control of the main/sub heater lamps is performed based on the fuser control temperature. The fuser
transmits between the five states (warm up, ready, standby, print, and low power) depending on the heat roll
surface temperature or printer conditions.
The fuser temperature control starts when the fuser ready in the system card assembly is turned on after a
preset time period has passed from power on. If a failure occurs, the heater lamps are turned off, the fuser
ready is turned off, and then the fuser temperature control is stopped.
Fuser lamp on/off control
The thermistor detects the heat roll surface temperature (fuser temperature) to regulate the temperature at the
target control temperature by turning on or off the heater lamp.
Fuser warm-up
The fuser warm-up starts at the time of power on, interlock open or close, jam reset, or return from the low
power mode, and ends when the ready temperature is attained, when a failure occurs, or when executing
diagnosis.
