Abstract: An image forming apparatus includes a waste toner system that collects waste toner in a waste toner container. An amount of waste toner collected in the container is increased by using a driven toner distributing member that distributes accumulated toner within the container. The toner distributing member may be driven by a shared speed-controlled motor that further drives an image forming process member. The waste toner system may detect the accumulation of waste toner by monitoring a drive control circuit while the toner distributing member is being driven. For example, a logic circuit may detect the accumulation of waste toner based on monitoring a predetermined frequency of interest of a frequency domain transform of a motor control signal, the frequency of interest associated with the shared motor driving the toner distributing member.

Abstract: A system and method of controlling the movement of a media sheet along a media path to correspond to the timing of a toner image on an intermediate transfer mechanism. A controller controls the timing and sends a pick command to move a media sheet from a pick tray into the media pathway at a time that the media can move at a process speed and intercept the toner image. The controller adjusts the speed of individual rollers within the media path to correct the timing of the media sheet to account for any timing inaccuracies. By the time the media sheet exits the media path and enters a media/image alignment region of the media pathway, the amount of positional error is reduced or eliminated.
