ABSTRACT:
An electrostatic copier having a control system wherein switches are used to detect conditions that would lead to paper jams. Such jams could result from sheets that are too short to be conveyed or as a result of overlong originals being copied during a copy cycle of an electrostatic copier of the coated paper type having an automatic document feeder. Circuitry is provided to re-sequence the system if copy paper is in transmit at the time of a power failure and the copy paper is located in a position that would result in a jam or an overlong copy sheet if the copier were to operate from a start mode.
