ABSTRACT:
A toner cartridge installation unit for an image forming device is disclosed which allows proper toner cartridge installation to take place. The installation unit includes at least one detection slot, and the toner cartridge includes a detection member. If the proper toner cartridge has been selected, or if certain foreign objects have not fallen into the installation unit, the detection member will slide into the detection slot, and a switch within the detection slot will be activated, thereby allowing installation to be completed. If the wrong toner cartridge has been chosen, or if certain foreign objects have fallen into the installation device, the switch will not be activated, the installation unit will discharge the toner cartridge from the image forming device, and the user will be alerted.
