- Be sure to place the removed Drum Unit (Bk) [1] on paper [2] or the like, and cover it with the drum
protection sheet [3] or wrap it with paper [3] (five or more sheets) so as to shield the drum, otherwise failure
may occur in the output image.
- Be sure to install the Drum Shaft Cap [1] to a position so that the hole [A] of the Drum Shaft Cap fits the
edge [B] of the Drum Drive Shaft [2] and at the same time the protrusion [C] of the Drum Shaft Cap fits the
groove [D] of the Drum Flange. When it is out of the position, turn the Drum Flange [3] "counterclockwise" so
as to align the position.
9) Push in the Black Developing Assembly Pressure Lever [1] to apply pressure.
