2.6.3. Fuser unit temperature control
When the main switch turns on, the CPU turns on the fusing lamp. The lamp stays on until the NC sensors detect the
standby temperature. Then the CPU raises the temperature up to the printing temperature.
■ Overheat Protection
The CPU cuts power to the fusing lamp in the following cases :
•
The temperature detected by the NC sensors keeps higher than 240°C for 20 sec.
The following components are used when thermistor overheat protection fails :
•
Two thermostats get into line with the common ground wire of the fusing lamp.
•
If one of the thermostat temperatures becomes higher than 195°C, it opens and cuts power to the fusing lamp. If the
other thermostat temperature becomes higher than 195°C, it also opens and cuts power to the fusing lamp.
