摘要:
A management server receives a notification from an image forming apparatus as to an operation mode of the image forming apparatus in response to an operation performed by a service person. The management server detects a status change in the image forming apparatus from the received notification. The management server then produces a replacement part list in accordance with management information stored in the management server and in accordance with the notified operation mode of the image forming apparatus and the detected status change. The management server transmits the produced replacement part list to the image forming apparatus.
