A dual job processing method of a multifunction peripheral having a carrier driver, a line feed driver and a scan driver, prevents power overload by avoiding overlapping actuation of the three drivers when dual job operations are requested. When an operation, that requires the use of the scan driver being requested while printing, is being performed by driving the carrier driver, the document scanning is performed by driving the scan driver, and the drive time for the line feed driver is delayed and initiated after the driving of the carrier driver is completed. When a request for printing is requested while scanning is being performed by driving the scan driver, printing is performed by driving the carrier driver, and the drive time for the line feed driver is delayed and initiated after driving of the carrier driver is completed. Accordingly, by avoiding the region where the actions of three drivers overlap, power overload can be prevented, the power supply device can be used with maximum efficiency and a problem such as power drop, which is derived from power overload, can be resolved.
