9.4 Developer Motor
9.4.1 Construction
The developer motor is a motor drives the following movements:
(A) Lifting movement by rotating the lifting cam in the black developer unit
(B) Rotational movement of magnet roller in the black developer unit
(C) Rotational movement of toner supply auger in the color developer unit
(D) Rotational movement of magnet roller in the color developer unit
Each movement is performed by drive transmission from the developer motor through the gears and
clutches.
The revolver unit contains three color developer units. The developer motor drives the color developer
unit only at the developing position; it means each developer unit does not have its own drive. When the
revolver rotates, the clutch turns OFF so that the drive of the developer motor will not be transmitted and
a damage to the gear will be prevented.
