Abstract

An electrophotographic printer means contains a process-controlled regulating arrangement for acquiring and regulating the critical operating parameters of the electrophotographic process. It comprises a first regulating stage for stabilizing the electrophotographic process on the photoconductor (12) by regulating the charging potential (18) the discharge illumination (17) and by acquiring and monitoring the residual potential (SL). It further comprises a second regulating stage for assuring and optimizing the development of the charge image by regulating the toner delivery to the developing region (14) and the inking of the charge image, and comprises a third regulating stage for assuring and optimizing the transfer printing by acquiring the specific characteristic quantities of the recording medium and regulating the corona means (UK).
