ABSTRACT:
A peripheral apparatus reserves and stores, on a nonvolatile storage medium, a first storage area which stores a control program for implementing a function of the peripheral apparatus, and a second storage area which stores a rewrite program for rewriting the control program. The firmware is formed from at least the control program and the rewrite program. When selectively switching and controlling a first mode for updating the firmware of the rewrite program, and a second mode for executing the control program, the first mode receives updating data of the control program from an external apparatus, rewrites the control program stored in the first storage area to updating data, using the rewrite program, determines that a rewrite operation is normally ended, and performs the rewrite operation again when the rewrite operation is not normally ended.
