Theory of Operation Ver. 8.0 Jun. 2008
C. < Overheat protection >
• If the abnormal high temperature of soft protection/hard protection cannot be detected
due to thermistor trouble, thermostat blocks the power supply to each heater lamp.
• The thermostat rating is 210 degrees centigrade for both the heating roller thermostat
and the pressure roller thermostat.
• The ratings do not, represent the actual surface temperature of the corresponding rollers,
since the thermostats are installed in a non-contact fashion with respect to each of the
rollers.
