ELECTROPHOTOGRAPHIC PROCESS CONTROL AND DIAGNOSTIC SYSTEM

摘要

A logic and control unit LCU (24) is configured to assess the viability of various subsystems in the electrophotographic marking process. The LCU determines a charging efficiency between a primary charger (28) and a photoconductor (18), establishes a reference voltage on the photoconductor, wherein the reference voltage corresponds to the charging efficiency, operat es a first subsystem in a non-print production mode to produce a first resultin g voltage on the photoconductor, and translates the photoconductor to a stationary sensor (50) for measuring the first resulting voltage.
