Abstract
A toner cartridge has a base and a slide slidably received in a slot of the base with at least one opening therein. A rotatable knob is inserted into the slide opening, wherein knob rotation results in a portion of the knob contacting a slide opening, thus moving the slide with respect to the base to one of a fully opened and fully closed position. The knob can include an eccentric cam which engages the slide opening to cause slide movement. The knob can have an axle which engages an opening in the base. The knob also can have a plurality of teeth on an outer edge thereof. The slide opening can have teeth which engage the teeth of the knob to move the slide with respect to the base.
