Abstract
A developer for an electrostatic reproduction machine has a dump door for opening and closing a discharge opening in the bottom of the developer. The door has two parallel channels formed therein and an actuator rod formed so that a portion of the actuator rod is slidably retained within each channel. The dump door is mounted to pivot about one of the channels toward and away from the discharge opening, a short support rod pivotally supporting one end of the door, and one end of the actuator rod supporting the other end of the door. The one end of the actuator rod is formed into a loop, the tip of which can be inserted into or removed from either of two openings in the developer housing by sliding the actuator rod in the channels. By inserting this tip into one of these openings, the dump door is locked in either an open or closed position. A switch mounted adjacent the support rod is closed to cause a count to be registered on a counter each time the dump door is opened.
