The developing rotary has a function to move the developing unit to the specified position.
5 types of developing units (L, Y, M, C, Bk) are stored inside the rotary.
When making prints, the developing rotary motor (M4) rotates the rotary counterclockwise. The mechanism is to make the 5-color developing units sequentially
face against the photosensitive drum.
The developing rotary motor (M4), a stepping motor, executes locking/unlocking of the rotary.
A sensor (PS21) is equipped in the rotary to detect the position of the rotary unit.
The DC controller controls these electric loads (M4, PS21).
