Patent ID: 8265514

Claim:
A method of operating a dry electrophotographic printer to remove toner from a skive mount, comprising: the printer providing a rotatable development member, an end block disposed at one end of the development member, the skive mount adjacent to the development member and connected to the end block, a backup bar operative in a first position to make physical contact with at least one point on the end block, and operative in a second position to lift away from the photoreceptor, and a timing device for measuring time intervals of printer operation; selecting a process-control time interval; selecting a cleaning time interval that is a non-negative multiple of the process-control time interval; producing prints using the printer until the process-control time interval elapses, as measured by the timing device; automatically producing a process-control patch in a process-control frame; repeating the producing-prints and producing-patch steps until the cleaning interval has elapsed; and in the process-control frame, automatically causing the backup bar to be in the second position, then, after a selected time delay, causing the backup bar to be in the first position, so that toner is removed from the skive mount.
