  • Preconditioning of photoreceptor and cleaner brush
    Patent number: 5771424
    Abstract: A preconditioning process and dual electrostatic brush cleaning apparatus for reducing adhesion of toner particles on the photoreceptor surface such that cleaning of the photoreceptor is enhanced. Preconditioning of the brush and/or the photoreceptor in the cleaning apparatus allows for cleaning of dual polarity toners, CAD toners and DAD toners. The preconditioning of the brush does not need replenishing once the print operation begins due to the electrostatics that maintain a constant predetermined level of toner in the brush.
