Abstract
Toner is removed from a skive mount in a dry electrophotographic printer. An end block is disposed at one end of the rotatable development member, and a skive mount disposed adjacent to the development member connects a skive to the end block. A timing device measures time intervals of printer operation. A process-control time interval and a cleaning time interval that is a non-negative multiple of the process-control time interval are selected. Prints are made until the process-control time interval elapses. A process-control patch is produced in a process-control frame. Once the cleaning interval has elapsed, in the process-control frame, a backup bar is lifted lift away from the photoreceptor, then, after a selected time delay, brought into physical contact with at least one point on the end block, so that toner is removed from the skive mount.
