<Number of changes: 2> The serial numbers of the affected machiens were added.

FS-C8020MFP, FS-C8025MFP

Topic

The following change was made in order to reduce the motion noise generated when the axis distance between the
fuser roller and press roller was automatically increased after printing to reduce the fuser pressure in the stand-by
mode.

Content of Changes

1) The tension of the spring (No.3) was reduced in order to reduce the motion noise (rattling noise) generated
when the gear is pulled to increase the axis distance between the fuser roller and press roller.

In-Field modification by case No modification necessary

Field Measure:

Please replace the spring with the new one (No.3) in case that the motion noise described above was pointed
by a customer.
(Please refer to the next pages for the procedures to replace the spring (No.3).)

Serial Nos. of the Affected Machines: (-->) Please refer to the tables on Page 4.

<Procedures to replace the spring (No.3)>

No. Procedures Details

Set the fuser pressure to the reduced side before
replacing the spring (No.3). Take out the fuser
unit to securely set it to the reduced side by
following the procedures below.

1

1) Set the machine to the state of “Ready to copy”

2) Open the right cover while the machine is powered ON.

3) Wait for six seconds while the right cover is open.
The fuser pressure is controlled so that it can be
automatically switched to the reduced pressure side even if
the pressure setting is at the increased side.

4) Take out the fuser unit from the machine after six seconds.

Remove the screw (x3) and take out the front
cover (COVER FUSER FRONT) of the fuser unit.

2

Remove the metal stop ring and take out the gear
