Abstract
The present application is directed to cartridges for use with an image forming device. The cartridge includes a body with an interior reservoir sized to contain toner, and an outlet to move the toner to the image forming device. A shutter is rotatably connected to the body and movable between a closed orientation to prevent toner from passing from the cartridge and into the image forming device, and an open orientation to allow toner to pass. A biasing mechanism is operatively connected to the shutter and the body of the cartridge. The biasing mechanism urges the shutter towards one of the open and closed orientations.
