(2) Cause
Uneven transfer due to the uneven condition of the transfer belt surface.
Up to 2000 prints after replacing drum unit to new one, the lubricant is gradually transferred to
the transfer belt then saturated. Meanwhile, the belt surface condition becomes uneven and
uneven transfer occurs.
The symptom tends to occur especially when the transfer belt, drum unit, intermediate transfer
belt and intermediate transfer cleaning unit are replaced as a set.
8mm interval is caused by the configuration of the auxiliary roller inside the intermediate transfer
cleaning unit.

To turn the unit to used condition, conduct color registration automatic adjustment.
Press [Utility/Counter]→[Administrator Setting]→[System Setting]→[Expert
Adjustment]→[Execute Adjust Operation] →[Color Regist. Auto.Adj]. Press OK then go back
to the usual screen. Adjustment is executed.
If the lines cannot be reduced, repeat it once more.
However, the maximum times of execution is 3 times. Because the cleaning blade failure may
occur.
