Measures against the Motion Sound (Clunk) When Applying
the Fusing Pressure
Model
FS-C8020MFP, FS-C8025MFP
Topic
The following change was made in order to eliminate the motion sound (clunk) which is generated when the center
distance between the heat roller and the press roller is automatically narrowed to apply the fusing pressure for print.
Content of Change
The fuser pressure system was changed from mechanical lock type to PI detection type.
<New type fuser unit>
Slit on cam

between the heat roller and the press roller.
There is a slit at the point where the specified fusing
pressure is applied. The motion sound (clunk) is
recognized when the cam is locked there.
In order to eliminate this motion sound (clunk), the fusing
pressure system was changed from mechanical lock type
to PI detection type where the cam rotation is stopped by
sensing the specified fusing pressure position with the PI
sensor.
