Abstract
A method and apparatus for adjusting the preclean corona current used in a printer or digital copier such that the preclean corona current is optimized for the dominant color entering the cleaner.
Claims18
A method of cleaning particles from an imaging surface, comprising:
- charging the particles on the imaging surface;
- developing the particles on the imaging surface;
- determining the color of the particles developed on the imaging surface;
- and
- changing the charge on the particles, in response to the color of the particles determined by said determining step thereby enabling optimal removal of the particles from the imaging surface.

A method of cleaning particles from an imaging surface, comprising:
- charging the particles for attraction of the particles onto the imaging surface;
- recording a latent image on the imaging surface;
- developing the latent image on the imaging surface with the particles;
- determining a color of the particles developed on the imaging surface by counting pixels to determine the color of the particles;
- adjusting a preclean current being applied to a corona generator, in response to the color of the particles determined by said determining step and
- changing the charge on the particles, in response to the color of the particles determined by said determining step, enabling optimal removal of the particles from the imaging surface.
