Make sure that the waste toner box is installed properly.

control panel (see

manually, take all the toner cartridges out of the drum unit and turn the drum 
unit over, then make sure that four drum unit gears are in the home position. 
The home position of each drum can be identified by matching the number on 
the drum unit gear to the same number on the side of the drum unit as shown 
in the illustration.
