Temperature detection section
To maintain the surface temperature of the fuser roller at a certain level, 3 thermistors (center, side and
edge) detect the surface temperature of the fuser roller to turn ON/OFF and control 2 heater lamps
(center and side).
1. Relation between the thermistor output voltage and surface temperature of the fuser roller
2. Control of the surface temperature of the fuser roller
Fig. 12-3
3. Temperature control for the both ends of the fuser roller
During continuous printing, the temperature of the end of the fuser roller (area where the paper does
not pass on) generally tends to be higher than that of other areas (areas where the paper passes
on). For this reason, the edge thermistor detects the temperature of the end of the fuser roller. When
this thermistor detects the abnormal temperature, the heater lamp is turned OFF regardless of the
temperature of the area where the paper passes on.
