Abstract
An insulative belt having a conductive pattern. A potential difference is applied to the conductive pattern on the insulative belt creating an attractive force that is exerted on the small particles of paper debris. This attractive force holds the paper fibers and paper dust on the insulative belt for subsequent removal, while allowing the cleaned paper sheet to move on through the electrophotographic system.
Claims10
A method of removing a plurality of dielectric particles from a sheet before the sheet contacts a photoreceptor at a transfer zone, comprising the steps of:
- energizing a plurality of conductors by applying a potential difference between adjacent conductors on an insulative belt to create an electric field with a non-uniform charge to attract dielectric particles on the sheet to the belt and hold the sheet in position;
- de-energizing the conductors;
- and
- removing the dielectric particles from the insulative belt.
An apparatus for removing a plurality of dielectric particles from a sheet before the sheet contacts a photoreceptor at a transfer zone, comprising:
- an insulative belt;
- a plurality of conductors disposed on said belt;
- means for energizing said conductors by applying a potential difference between adjacent conductors to create an electric field with a non-uniform charge to attract the dielectric particles on the sheet to the belt and hold the sheet in position;
- means for de-energizing said conductors;
- and
- means for removing the dielectric particles from the belt.
A device for removing a plurality of dielectric particles from a sheet before the sheet contacts a photoreceptor at a transfer zone, comprising:
- an insulative belt;
- a plurality of conductors defining a pre-selected pattern on said insulative belt;
- and
- means for applying a potential difference between adjacent conductors creating an electric field with a non-uniform charge that attracts dielectric particles from the sheet to said belt.
