摘要： A data collecting unit receives a plurality of types of status data from an image forming apparatus and stores the status data in a status database. A data generating unit generates a plurality of types of target data for determining a maintenance sign, based on the status data. A first determining unit determines whether each of the status data exceeds a predetermined reference value. A second determining unit performs weighted majority decision based on a determination result from the first determining unit and a weight value set for each of the status data, and determines whether there is a maintenance sign taking all the status data into consideration.

摘要： A determining unit determines whether the printer is in the predictive failure state based on the internal information of the printer acquired by the information acquiring unit. A failure risk computing unit performs a failure risk determination process for determining the size of failure risk of the printer when the printer is in the predictive failure state. The determination result is reported to a maintenance person or a user. In this way, the maintenance person or the user who receives the report can definitely grasp a degree of urgency of maintenance at that point.
