The gear [A] and cam gear [B] on the fusing knob shaft at the front of the fusing
unit are always engaged. The actuator [C] for the oil pump roller is in contact with
this cam gear.
When the fusing drive gear rotates causing the fusing knob to rotate, the gear and
cam gear on the fusing knob shaft rotate. This rotates the roller of the actuator
following the cam about pin [J], thus pressing the oil pump sleeve [F] to supply oil
to the oil supply pad [D]. Excess oil is collected in the oil tank [E].
At both ends of the oil pump sleeve [F] are valves, which prevent oil from flowing
back.
The oil supply roller [G] copier applies oil to the hot roller by pressing the oil supply
pad [H] against the supply roller. The fusing oil blade [I] prevents oil from being
applied unevenly.
