10.2 OIL SUPPLY MECHANISM
The oil supply is necessary for a 40 cpm copier. An oil supply roller [A] is
installed above the hot roller [B]. It is always in contact with the hot roller, and
applies a light coat of silicone oil as the roller rotates.
The oil supply roller is made of paper soaked with silicone oil wrapped
around the shaft, and covered with PTFE (polytetra fluoroethylene) tube. As
the temperature of the hot roller rises, the PTFE tube contracts and squeezes
the oil-soaked paper, and the oil comes out through the coating.
The oil supply roller cleaning brush [C] under the oil supply roller removes the
toner and paper dust accumulated on the oil supply roller.
The oil supply roller shaft is installed on a one-way bushing [D], to prevent
collected toner from returning to the hot roller surface by the customer
operating the fusing knob manually in the reverse direction.
