This time, the description with (-->) was revised from the previous information.
<Number of changes: 9> The part name was corrected from cam to joint. The permanent measures were added to the pages 3 and 4.
[Notes] When refitting the drive unit, please make sure to insert the following shaft (X in the figure) into the (-->) joint of the drive unit, and then fix the drive unit. Afterwards, please check if the (-->) joint (X) is inserted in the gear on the machine front side.
[Phenomenon when the shaft (X) comes off] If the shaft (X) comes off, some abnormal noise from the intermediate transfer unit might be recognized or toner might leak from the retainer section. (Please refer to the next page for more details on the mechanism.)

[Procedures how to refit the drive unit]
<Mechanism of the phenomenon when the shaft (X) comes off>
1) The spiral (A) to convey the waste toner collected from the intermediate transfer unit to the retainer section does not rotate. Therefore, waste toner accumulates in the cleaning screw section inside of the intermediate transfer unit. As a result, some abnormal noise might be generated by skipping of the teeth of the machine side gear to drive the cleaning screw.
2) The drive transmission part (B) to the spiral inside of the retainer section does not drive. Therefore, the spiral is not rorated to convery the waste toner collected from the intermediate transfer unit and the drum unit to the waste toner bottle. As a result, the waste toner excessively accumulated inside of the retainer section might leak.
