Abstract

Eine Logik- und Steuereinheit (LCU) (24) ist so eingestellt, dass sie die Funktionsfähigkeit der verschiedenen Untersysteme (28, 30, 34, 38, 40, 42, 43, 46, 47, 48, 49, 50, 51, 76), in dem elektrofotografischen Markierungsvorgang auswertet. Die LCU (24) bestimmt eine Ladungseffizienz zwischen einer ersten Ladestation (28) und einem fotoleitenden Element (18), erzeugt eine Referenzspannung auf dem fotoleitenden Element (18), wobei die Referenzspannung der Ladungseffizienz entspricht, betreibt ein erstes Untersystem (28, 28a, 28b, 30) in einem Nicht-Druckbetrieb, um eine erste resultierende Spannung auf dem fotoleitenden Element (18) zu erzeugen und übergibt das fotoleitende Element (18) an einen ortsfesten Sensor (50) zum Messen der ersten resultierenden Spannung.

A logic and control unit (LCU) (24) is set so that it functions the various subsystems (28, 30, 34, 38, 40, 42, 43, 46, 47, 48, 49, 50, 51, 76 ), in the electrophotographic marking process. The LCU (24) determines a charge efficiency between a first charging station (28) and a photoconductive element (18), generates a reference voltage on the photoconductive element (18), the reference voltage corresponding to the charge efficiency, operates a first subsystem (28, 28a, 28b, 30) in a non-printing operation to generate a first resulting voltage on the photoconductive element (18) and transfers the photoconductive element (18) to a fixed sensor (50) for measuring the first resulting voltage.
