Abstract

To clean toner from a photoreceptor in a xerographic machine, an apparatus using a fine mesh web is employed. The web 10 is held taut and stationary against the photoreceptor 12 as the latter moves. Holes in the web should be at least 50 to 100 microns to prevent the web from becoming clogged with the toner. A nylon screen of about 100 to 200 mesh is suggested.

To clean toner from a photoreceptor in a xerographic machine, an apparatus using a fine mesh web is employed. The web 10 is held taut and stationary against the photoreceptor 12 as the latter moves. Holes in the web should be at least 50 to 100 microns to prevent the web from becoming clogged with the toner. A nylon screen of about 100 to 200 mesh is suggested.

To assist in the cleaning, the photoreceptor is simultaneously flooded by lights 14 and subjected to AC corona by corona wires 16. The loosened toner is carried away by vacuum to a conventional collector such as a filter, a cyclone separator or an electrostatic precipitator. The shields 18 surrounding the lights and corona wires are open at the ends to allow clean air in during the cleaning operation.
