Rattling sound from the Fuser unit during stand-by mode
Creation Date: 05/10/2011
Model: FS-C8020MFP/8025MFP
Phenomenon Motion sound (Rattling sound) may arise from the Fuser unit while the machine is in
stand-by mode.
Cause Motion sound may be generated, when pulling the gear to increase the center distance
between the fuser and press roller during stand-by mode.
Solution The tension of the Spring drive press (302K025751) has been reduced, to reduce motion
sound. Refer to page 2 for the installation procedure of the Spring drive press.
