2.9.3 FUSING UNIT
Fusing Mechanism
The hot and pressure rollers each have a fusing lamp: 800 W [A] for the hot roller
[B] and 400 W [C] for the pressure roller [D]. The hot roller thermistor [E] and
pressure roller thermistor [F] control the temperature of these lamps.
Temperature control is accomplished normally by turning the fusing lamps on and
off. Phase control can be selected using an SP mode (SP1-104).
The hot roller thermofuse [G] blows at 184°C and the pressure roller thermofuse
[H] blows at 167°C. These thermofuses prevent the temperature in the fusing
section from rising to dangerous levels.
Fusing Temperature Control
The fusing temperature depends on the selected copy modes, as shown below.
The defaults indicated in the table can be adjusted with SP modes.
