摘要：
An apparatus in which a developer unit of an electrophotographic printing machine has a plurality of wires which trap contaminants before reaching electrode wires positioned between a donor roller and a photoconductive surface. In addition, a circuit determines when defects and deletions are caused by contaminants spacing the electrode wires from the donor roller.
