The fusing unit is a hot roller/pressure roller system.
B064 Series
Two 550W fusing lamps switch on and off at the same time to keep the hot roller
temperature steady at 185°C.
The center thermistor (1) (not in direct contact with the hot roller) controls the
temperature at the center of the hot roller. The end thermistor (3) directly contacts
the hot roller surface and prevents overheating. The two thermostats (2) also
prevent overheating.
