<p>Machine discrimination data stored in an information storage area of a memory in a body of an image formation apparatus is read, and data stored in a machine information storage area of a memory in a cartridge mounted in the image formation apparatus is read. If the data in the cartridge is not "0", it is judged whether or not the data in the body is identical with the data in the cartridge. If not identical, an error flag is set into "1", and it is considered that a mounting error occurs, and controlling to prohibit image formation is performed. On the other hand, if the data in the cartridge is "0", the mounted cartridge is considered as an unused cartridge, and the machine discrimination data of the body is stored in the mounted cartridge. <IMAGE></p> |
