Measures against the Color Registration Shift
(Change of the Secondary Transfer Roller Diameter)
Model
This time, the description with (-->) was revised from the previous information.
<Number of changes: 2> The actual serial numbers of the affected machines were added.
FS-C8020MFP, FS-C8025MFP
Topic
The color registration shift might occur depending on the operating environment for the machine in the environment
with high temperature and high humidity. The following changes were made in order to control the slippage between
the drive roller and the primary transfer belt at high humidity.
Content of Changes
1. The diameter of the secondary transfer roller was increased in order to increase the primary transfer belt
drive force to control the slippage.
2. The shape of the transfer roller gear was changed in order to cope with the increased drive torque after the
change above.
3. The protection sheet for the spare part secondary transfer roller was changed to plastic film after the
change above. (The protective sheet is applied since the ribs at the neighboring guide plate may contact.
The protection shall be improved for the roller with larger diameter after the sheet was changed to the
film.)
4. Since the process speed should be readjusted when the old parts were replaced with the new one after the
change above, a leaflet describing the change of the U053 (Setting the adjustment of the motor speed) is
now bundled in the new parts (Nos.1 and 2) and in the MK-895A.

Field Measure:
Please replace the parts (Nos.1&2) with the new ones when the phenomenon described above occurs. Also,
please check and change the maintenance mode U053 values by referring to the bundled leaflet.
Then, please make sure to execute what is described in “Note when adjusting the color registration” on the
service bulletin SB-2KZ-0011-B240.
Serial Nos. of the Affected Machines: KMAS/KMBR/KMA220V : Planned from the August 2011 production*
Others : After using up the old stock
*The above is the plan at the present moment. Please note that this information is subject to change.
