18-5. Fusing Temperature Control
●
The Fusing Unit is provided with two heater lamps, each turning ON to provide fus-
ing temperature control at a particular timing so that power consumption can be
minimized.
* During the Energy Saver mode, the Lower Fusing Roller temperature is controlled at
100°C in stead of the normal 140°C, while the Upper Fusing Roller temperature is
controlled at 190°C as in the normal timing.
* “Temperature control” refers to the process of turning ON and OFF the heater lamps
to arrive at a predetermined temperature.
* “Temperature control completed” means the predetermined temperature has been
reached.
◆
Example: The copier is turned ON when the Upper and Lower Fusing Rollers are
cool in the morning and a copy cycle is run following the completion of
warm-up.
