The Imaging Unit Motors drive the Imaging Unit drums, toner Agitation Bars and

Agitation Gears. Imaging Unit drive varies depending on the print mode. In addition

to the developing components, the Cyan Imaging Unit Motor uses a Lift Uplink

mechanism to raise the CMY Imaging Units during monochrome printing. When the

Cyan Imaging Unit Motor rotates (CCW), the Lift Uplink slides to the left, and as

indicated in the figure below, each Imaging Unit moves down for color printing.When

the Cyan Imaging Unit Motor rotates (CW), the Lift Uplink slides to the right, the

CMY Imaging Units move up for black and white printing.
