Fusing
SM 6-61 G133
Detailed
Descriptions
thermistor detects the temperature at the end.
Temperature is normally controlled by turning the fusing lamp and the IH system on
and off.
The lubricant roller supplies a small amount of oil to the pressure roller through the
cleaning roller. An oil supply unit is not necessary because the amount of oil supplied
to the pressure roller is small.
6.9.2 FUSING UNIT DRIVE
Belt and Rollers
The fusing/paper exit motor [A] drives the pressure roller [B] and the fusing roller [C]
through the gear train. The heating roller [D] is driven by the pressure with the fusing belt
[E]. The lubricant roller [F] and cleaning roller [G] are driven by the friction with the pressure
roller.
Lubricant Mechanism
The lubricant roller [F] contains silicone oil in its material. The lubricant roller applies small
amount of silicone oil to the pressure roller to reduce the friction between the pressure
roller and thermistor, and stripper pawl so that white lines on the output are reduced.
The cleaning roller [G] cleans the lubricant roller to remove the residual toner stuck to the
lubricant roller.
