A copying or printing machine including a microcomputer having a random access memory in which a set of coded signals may be written in and read out; a read only memory having a sequence control program for accomplishing a copying or printing operation; a processing unit operative for reproducing a copy of an original; a power supply for energizing the machine; and a power reducing device for reducing electric power to be supplied to an image fixing portion of the machine by the power supply so that less electric power is consumed than in normal standby status. If an interrupt mode is established during a copy run, copying conditions relevant to the previous copy run are stored in the RAM and an interrupt copy run is performed. During the interrupt mode, the power reducing device is inhibited from reducing electric power to be supplied to the image fixing portion of the machine.
