Abstract
In a method or system for controlling an electrophotographic printer or copier that has at least one developer station, a toner discharge from the developer station is detected during the print operation and a developer regeneration process is started when the detected toner discharge fulfills a predetermined first regeneration criterion. A charge image is generated on the photoconductor, the charge image is developed by the developer station, and the developed image is removed by a cleaning device without being transferred as printed onto a recording medium. New toner is introduced into the developer station. Also in accordance with the method or system for controlling an electrophotographic printer or copier that has at least two developer stations, during a print operation the print data is used to determine which developer stations are needed for printing of the data. In the event it is established that a developer station was not needed or will not be needed, the developer station is shifted into a standby state in which at least one part of mechanical actuators of the developer station is stopped.
