Abstract
A balanced photoconductor usage control system for an electrophotographic copier/printer machine having a photoconductor containing thereon two page images areas, is employed to solve the problem of excessively high background level due to toner filming. More specifically, the control system includes memory means for retaining a location of a last page image area which was last used to produce a page, and control means jointly responsive to a presence of a full page condition in a page buffer, and to the memory means to effect production of a next page on an alternate page image area.
