Abstract: A failsafe system is provided for a copying machine which will operate in response to one of a plurality of sensing devices to stop the xerographic copying process, immediately deenergize the fuser assembly and energize an auxiliary drive system which will merely return the reciprocatable document carriage to the home position so that the original document may be retrieved. When the document carriage reaches the home position, the auxiliary drive system will be shut off with the cover latching mechanism deactivated to prevent the initiation of further cycles until such time as repairs are made and the system is reset for normal operation.
