Abstract
The present application is directed to retainers and methods of retaining a developer unit within an image forming device. One embodiment may include positioning a retainer attached to a frame at a first position with a second end of the retainer positioned away from the developer unit. A toner cartridge may be inserted into the image forming device in a vertical direction and contact against retainer. The toner cartridge may laterally move the retainer relative to the frame from the first position to a second position with the second end positioned to prevent removal of the developer unit from the frame. Another embodiment features a system to retain a developer unit in an image forming device. The system may include a frame configured to receive the developer unit and the toner cartridge. A retainer may be movably attached to the frame and include a first end with a ramped surface, and a second end spaced away from the first end. The retainer may be movable between a first position prior to insertion of the toner cartridge with the second end positioned away from the developer unit, and a second position after insertion of the toner cartridge with the second end positioned to prevent removal of the developer unit from the frame.
