Abstract
A logic and control unit (LCU) is configured to assess the viability of various subsystems in the electrophotographic marking process. The LCU determines a charging efficiency between a primary charger and a photoconductor, establishes a reference voltage on the photoconductor, wherein the reference voltage corresponds to the charging efficiency, operates a first subsystem in a non-print production mode to produce a first resulting voltage on the photoconductor, and translates the photoconductor to a stationary sensor for measuring the first resulting voltage.
