Topic
The cassette lift plate might be deformed by deterioration and accordingly the paper position might be lowered if the conditions below are met (especially for the main unit cassette). Then, the remaining paper might not reach the remaining paper detection actuator, which caused faulty detection of paper empty. Therefore, the following changes were made. Since some attention is required when replacing the parts, please refer to [Field Measures] below.
Conditions
-The cassette heater is always ON (influence of heat).
-A large stack of maximum size paper is loaded for a prolonged time (influence of roads)s

(*2) |
|
|
|
|
|
(*1) This phenomenon does not occur on the TASKalfa 2550ci and PF-790 since the metal plate under the lift plate has drawing compound. However, the change was also applied for common use of the part.
(*2) The actuator was not changed for the FS-C8020MFP, FS-C8025MFP and TASKalfa 2550ci since the shape of the actuator and mechanical structure are different.

Field Measure:
(1)FS-6025MFP, FS-6025MFP/B, PF-470, PF-471, FS-6525MFP, FS-6530MFP
Replace the lift plate (No.5, No.7) and actuator (No.8) with the new ones at the same time when the phenomenon described above arises.
(2)FS-C8020MFP, FS-C8025MFP
Replace the lift plate (No.5) with the new one when the phenomenon described above arises.
*Please refer to the page 4 and after for the procedures how to replace the lift plate and the actuator.
(3) PF-790 Use a set of the old types or the new types when replacing the parts.
(4) TASKalfa 2550ci No particular problem is expected.
Serial Nos. of the Affected Machines: Please refer to the page 6.
