摘要： A powder-amount detection device includes a first electrode, a second electrode, a third electrode and a voltage detector with the second electrode adjacent to the first electrode on the powder container and have a smaller surface area than a surface area of the first electrode. The third electrode is on a side opposite to the second electrode with the powder container interposed between the third electrode and each of the first electrode and the second electrode. The voltage detector detects voltages of the first electrode and the second electrode by detecting charging and discharging behaviors of the first electrode and the second electrode when a voltage is applied between the third electrode and each of the first electrode and the second electrode for a short time, and detects the amount of powder in the powder container based on the voltages of the first electrode and the second electrode.

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.
