[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.
