Patent ID: 7532845

Claim:
A corotron assembly comprising: a corotron shield having a base and parallel walls arranged in a U-shaped configuration; an electrically conductive coronode having a plurality of field emitters, each field emitter having a terminating end, the terminating ends of the field emitters being spatially separated from one another, the coronode being located within the U-shaped corotron shield; and a pair of paper edge guides, each guide having a plurality of generally planar members that are arranged in two groups, members of a first group of generally planar members are arranged in a row that parallels one side of the coronode and members of a second group of generally planar members are arranged in a row that parallels an opposite side of the coronode, each member of the first group of generally planar members are further arranged in the row to be aligned with a member of the second group of generally planar members on the opposite side of the coronode, each of the paper edge guides being configured to extend between one of the field emitters and one of the walls of the corotron shield and the generally planar members of the paper guides have a height that extends above the terminating ends of the field emitters.
