摘要：
A time point at which a predetermined period elapses since the start of use of a copying machine as a detection subject after factory shipment or repair is obtained. Pieces of set information, which are combinations of various types of information until the time point is reached are sequentially stored to construct a normal set information group. After the time point is reached, presence of abnormality in the copying machine is determined based on the normal set information group and the various types of information obtained.
