ABSTRACT:
An electrophotographic processor including an operating lever which is fixed to a shaft. An agitator gear, mounted about the shaft, has a groove configured to receive a protrusion extending from the operating lever, the groove and protrusion defining a helical formation. When the drive gear of a drive motor drives the agitator gear, the helically-formed groove-and-protrusion convention urges the agitator to drive the operating lever, thus drive the shaft and agitator to stir the toner. When the control lever is rotated manually, the protrusion acts against the groove and urges disengagement of the agitator gear and drive gear.
