Abstract
A dry electrophotographic printer is operated to remove toner from a longitudinal member. A process-control time interval, and a cleaning time interval that is a positive multiple thereof, are selected. Prints are produced until the process-control time interval elapses, as measured by a timing device. A process-control patch is produced in a process-control frame. This is repeated until the cleaning interval has elapsed. In the process-control frame, after the cleaning interval elapses, the photoreceptor and development member are spaced apart, then, after a selected time delay, brought into operational relationship, so that a stop at one end of the photoreceptor contacts an end block at one end of the development member, and toner is removed from the longitudinal member, which is connected to the end block.
