  • Photoreceptor with internal waste toner container
    Patent number: 5933696
    Abstract: A photoreceptor assembly and a xerographic cassette for a printing or copying machine, the cassette including a photoreceptor drum, a drum cleaner, a waste toner container, for storing waste toner; and a waste toner conveyor for conveying waste toner cleaned off said photoreceptor drum by the cleaner into the waste toner container characterized in that the waste toner container is positioned in the interior of the photoreceptor drum and is reversibly removable therefrom. The conveyor typically includes a flexible helical wire which acts as an auger. Once filled with waste toner, the waste toner container is removed from the drum and is replaced by a fresh container.
