9.3.2.4 Copying Temperature Control
0006-6584
iR2270 / iR2870 / iR3570 / iR4570
The machine uses this mechanism to control the temperature of the fixing heater to an optimum level while a
recording medium is passing through the fixing film assembly; specifically,
1.the machine varies the power ratio in relation to the difference between the temperature detected by the thermistor
and the target control temperature.
2.if the temperature detected by the thermistor is higher than the target control temperature for a specific period of
time (0.6 sec), the machine will decrease the power ratio; if lower, it will increase the power rate.
