Abstract
An improved detack corotron reduces the likelihood of a paper jam arising from a curled paper edge getting caught in the corotron. The detack corotron includes 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, and a paper edge guide having a plurality of generally planar members, the generally planar members being perpendicular to the conductive coronode and the generally planar members having a height that extends above the terminating ends of the field emitters.
