Abstract:
1. An image forming apparatus, comprising: a unit having a first non-volatile memory holding recognition information of the unit; and a main body in which the unit is installed in a replaceable manner, the main body has a second non-volatile memory holding second recognition information corresponding to the unit, wherein the image forming apparatus is configured to exchange information with an administration system monitoring a status of the image forming apparatus, and when a comparison is made between the recognition information held in the first non-volatile memory of the unit and the second recognition information held in the second non-volatile memory of the main body and the recognition information held in the first non-volatile memory does not accord with the second recognition information held in the second non-volatile memory, information is transmitted to the administration system, and wherein the second recognition information is a plurality of recognition information corresponding to a plurality of units, and when a comparison is made between the recognition information held in the first non-volatile memory of the unit and the second recognition information held in the second non-volatile memory of the main body, and the recognition information held in the first non-volatile memory does not accord with at least one of the plurality of recognition information of the second recognition information held in the second non-volatile memory, information is transmitted to the administration system.
