In an electrophotographic machine, adjustment of the preclean corona current level can improve copy quality by improving the removal of residual toner performed at the cleaning station. An endblock is disclosed for mounting a corona-generating wire at a variable distance from the photoconductor carrying the residual toner. In that manner, the current deposition on the photoconductor can be adjusted to achieve good cleaning. Figs. 1-4 show insulating end blocks 1 and 2 for mounting a corona wire 8 upon which a high voltage is placed. Endblocks 1 and 2 are located in a metal housing (not shown) for unifying the corona structure and providing electrical shielding thereto. Corona wires 8 attach to endblock 1 through spring 5 that hook into a metal support which is held in place by endblock 1.
