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.)

Refit the drive unit (*).

* DR-895 (302K09312_)

Remove the left lower cover, the
main PWB and the intermediate
transfer unit to insert the shaft (X)
into the (-->) joint of the drive unit
from the aperture of the metal plate
behind the main PWB.

Insert the shaft (X) into the (-->) joint of the drive
unit.
(Note) At this time, check if the front end of the shaft

(X) is inserted in the gear on the machine
front side.

[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.

Permanent measures
The shape of the shaft (No.1) and the BASE TERMINAL (Not supplied) was changed so that the shaft removed
from the joint of the drive unit will not fall off when detaching the drive unit and the shaft can be smoothly inserted
into the joint of the drive unit when reattaching the drive unit.
