ABSTRACT:
A developer unit for an electrophotographic printer includes a housing defining a chamber for retaining developer material. An auger is rotatable within the chamber for the conveying of developer material within the chamber. The auger and a second rotatable member are adapted to receive rotational drive from a single source of rotational motion. A clutch is responsive to a torque above a predetermined level associated with the auger. A selectably openable outlet port is adapted to permit escape of developer material from the chamber. A linkage is operatively disposed between the clutch and the openable outlet port. A torque above a predetermined level associated with the auger causes the clutch to move the linkage, causing the mechanical linkage to open the outlet port.
