When the developing disengage drive unit is properly set to its home
position, the gear [4] does not rotate if turning the gear [2], and there will
be no sense of resistance when rotating the gear [2].
2. Alignment in installing the developing disengage drive unit
When installing the developing disengage drive unit while the main drive
unit is removed, the corresponding gears of the host machine need to be
aligned (interlocked).
Tighten the 2 screws [1] to the developing disengage drive unit [3] and
tighten the screw [2] halfway to confirm the alignment of the gear [4] and
the gear [5].

the triangle and the elongate hole of the gear lie right next to each other.
