ABSTRACT:
A cartridge lockout system and method for an image forming apparatus, which includes a cartridge and a wheel rotatably mounted on the cartridge. The wheel has a plurality of digital indicators, each digital indicator being in a first condition or a second condition. A sensor is secured to the image forming apparatus adjacent the digital indicators for sensing the digital indicators and the first and second conditions of the digital indicators and producing a sensor signal during rotation of the wheel. Further included is an engine that has a machine class code and a cartridge support registry data table stored therein. The engine is in electrical communication with the sensor, receives the sensor signal, generates a cartridge class code based on the sensor signal, compares the cartridge class code to the machine class code, and disables operation of the engine if the cartridge class code does not match the machine class code in the cartridge support registry data table.
