21-2. Fusing Rollers Pressure Mechanism
Pressure Springs are installed on both ends of the Lower Fusing Roller.
These springs contact the bearings mounted on both ends of the Lower
Fusing Roller and exert pressure through the Lower Fusing Roller to the
Upper Fusing Roller which is installed in the Fusing Unit.
The Fusing Unit is divided into an upper and a lower half, and the upper half
can be swung open. The Upper Half of the copier, when locked in position,
presses the upper half of the Fusing Unit down onto its lower half.

21-3. Oil Roller
A felt-type silicone oil roller, the Oil Roller, is pressed up against the Lower
Fusing Roller by the Torsion Coil Springs fitted on the bushings on both
ends of the Oil Roller. The Oil Roller applies a coat of silicone oil to the
surface of the Lower Fusing Roller. From there, it is transferred to the
surface of the Upper Fusing Roller to help prevent toner from being melted
onto the surface of the Upper Fusing Roller.
