  • Xerographic cassette with dual waste toner storage
    Patent number: 5778296
    Abstract: A xerographic cassette for a printing or copying machine includes a photoreceptor drum, a cleaning blade, and a waste toner conveyor for conveying waste toner cleaned off the photoreceptor drum by the cleaning blade into the interior of the photoreceptor drum for storage. The conveyor includes a flexible helical wire which acts as an auger. A curved tube portion of the conveyor passes through an auxiliary waste toner container. Once the auxiliary container is substantially full, waste toner is conveyed into the interior of the photoreceptor drum. The auxiliary container is provided with an aperture which enables it to be emptied, thereby prolonging the useful life of the cassette.
