Multi-function erase lamp

A multi-function, multi-segment ac plasma erase lamp is provided to selectively erase previously charged areas of a photoconductive member. The lamp performs the conventional erase function of fixed edge erase, edge shift and patch generation, while adding the functions of variable edge erase along...

description	A multi-function, multi-segment ac plasma erase lamp is provided to selectively erase previously charged areas of a photoconductive member. The lamp performs the conventional erase function of fixed edge erase, edge shift and patch generation, while adding the functions of variable edge erase along an edge to accommodate reduction images and changes in page size. Another feature of this erase lamp is a "dark" segment which is energized but is not light emitting. Its function is to enhance the turn on time for the light emitting segments. A still further improvement is the application of a voltage to a photoresist coating applied the the lamp surface to create a field which will repel toner and dust particles from that surface of the lamp.
