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
Content of changes
No. Details Affected Models
The material of the lift plate was changed for heat
1 resistance. (No.5,No.7) All models
Lift plate (PC+ABS PC) (*1)
change The lift plate was newly set up as service part
2 Except TASKalfa 2550ci, PF-790
(No.5) due to the change 1) above.
The shape of the actuator (No.8) was changed due
to the change 1) above. FS-6025MFP, FS-6025MFP/B, FS-6030MFP,
Actuator
3 (The new type lift plate is heat-resistant, but less FS-6525MFP, FS-6530MFP,
change
rigid. It may bend and fail to detect paper full. PF-470, PF-471, PF-790
Therefore, it was changed as above.) (*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.
