ABSTRACT:
An apparatus (100) useful in printing for charging a photoconductor and for cleaning a scorotron grid is disclosed. The apparatus can include a scorotron frame (110) and a scorotron charge member (120) coupled to the scorotron frame, where the scorotron charge member can be configured to generate an electric field. The apparatus can include a scorotron charging grid (130) coupled to the scorotron frame, the scorotron charging grid having a length axis, a width axis, and a height axis, and the scorotron charging grid including a scorotron charging grid surface having a plurality of openings. The apparatus can include a scorotron charging grid cleaner (140) coupled to the scorotron charging grid, where the scorotron charging grid cleaner can be configured to travel along the scorotron charging grid length axis and clean the scorotron charging grid. The scorotron charging grid cleaner can include a scorotron charging grid cleaner center and scorotron charging grid cleaner ends at opposite ends from the scorotron charging grid cleaner center along the width axis. The scorotron charging grid cleaner can extend further in a direction of the height axis at the scorotron charging grid cleaner center than at the scorotron charging grid cleaner ends.
