Fusing Temperature Control
The fuser heater is turned ON immediately after the main power is switched on.
If there is no output signal when the main motor operates at 125
˚C, READY status is
maintained at 175
˚C.
If there is an output signal, fusing temperature is maintained at 180
˚C for fusing paper.
(180
˚C is the default value for standard paper)
Different fusing temperature is set for each paper type.
Fusing temperature is configured differently for each paper, but may be changed within a
certain range by the user.
Heater power is turned OFF when an error occurs or when printer enters Power Save
mode.
Overheat Prevention
When Fusing Roller’s temperature rises higher than 230˚C, CPU cuts off fusing lamp power
and generates ERORR message at the same time.
To prepare for when the thermistor fails to prevent overheating, 2 thermostats have been
added next to the general grounding cable of the fusing lamp. A thermostat cuts off power
