1. Alignment of the Gears in the Main Drive Unit
When mounting the main drive unit, the gears [A], [B], and [C] at the host
machine should be interlocked with their mating gears.
The procedure for gear alignment is as follow:
1-1. How to Align the Gear [A] at the Host Machine Side
1) Align the elongate hole [2] of the gear with the triangle [1].
1-2. How to Align the Gear [B] at the Host Machine Side
1) Align the elongate hole [2] of the gear [5] with the triangle [1].
2) Interlock the teeth of the gears [5] and [6] so that the holes [3] of the
gears will lie right next to each other.
3) Interlock the teeth of the gears [6] and [7] so that the holes [4] of the
gears will lie right next to each other.

In the alignment procedure from 1-1 to 1-3, the teeth of the gears must be
aligned exactly as is shown in the pictures.
2. Alignment of Developing Estrangement Drive Unit
2-1 Alignment of Developing Estrangement Drive Unit in Assembling
Rotate the gear [2] of the developing estrangement drive unit[1] to the
direction of the arrow, and align the solenoid claw [3] with the position
of the cut-off in the gear (home position).
When the developing estrangement drive unit is properly set to its
home position, rotating the gear [2] does not make the gears [4] rotate
and also there will be no sense of resistance when rotating the gear [2].
2-2 Alignment of Developing Estrangement Drive Unit in Mounting
Tighten the 2 screws [1] to the developing estrangement drive unit[3]
and tighten the screw [2] halfway, then confirm the alignment of the
gears [4] and [5].
