Abstract
An automatically self-aligning charging device assembly for producing a layer of charge on a charge holding surface in alignment with a document registration position on the platen of a machine. The assembly includes a charging element having a start-of-charging position thereto, and a housing enclosing the charging element. The assembly also includes a stop member mounted to the frame of the machine at a first side of the platen for contacting a first end of the housing at a desired point so as to automatically align the start-of-charging position of the charging element with the document registration position. A resilient force applying member connected to a second end of the housing automatically absorbs corrective adjustments to a location of the start-of-charging position of the charging element relative to the document registration position on the platen, thereby automatically aligning the start-of-charging position with the document registration position.
