29. An image forming apparatus for forming an image in accordance with control codes, said image forming apparatus comprising:
-
a printing unit for printing an image;
a plurality of code memories for storing control codes which are adapted to control the image forming apparatus having said printing unit; and
a processor for controlling the image forming apparatus in accordance with the control codes stored in at least one of said plurality of code memories, wherein, after a power supply is turned on, said processor determines whether rewriting of the control codes has suspended or failed, said processor determines which one of said plurality of code memories was being rewritten if the rewriting of the control codes has suspended or failed, said processor controls transfer of new control codes from an external apparatus, and said processor controls rewriting of the control codes, which have been stored in the determined one of said plurality of code memories, with the new control codes transferred from the external apparatus in accordance with rewrite execution codes which are adapted to execute rewriting of the control codes and are transferred from the external apparatus.
