Photoconductor advance system for copiers and the like

摘要

Photoconductor panels are automatically replaced in an electrophotographic copier or printer after it is determined that the panels require replacement and the machine has entered into a run-out mode. The run-out mode is defined as the time period at the end of a copy processing operation between the transfer of the last image to a copy sheet and the final processing of that copy sheet by the machine. The photoconductor panel is completely replaced without interrupting machine operation and in a manner transparent to the user. A control circuit or process interprets the machine states to determine presence of the run-out mode.
