Abstract
A method of controlling the movement of copy sheets along a copy sheet path by providing a target by a high level controller for the movement of copy sheets within the copy sheet path and controlling movement of copy sheets within segments of the copy sheet path. Movement in each segment is controlled by subcontrollers activating segment drives. Feedback data are conveyed to the high level controller and to other subcontrollers on the movement of copy sheets within segments of the copy sheet path and copy sheet movement is adjusted by the copy sheet drives of selected segments of the copy sheet path in order to achieve the target.
