摘要： A system abnormality determining method comprises the steps of transmitting fake abnormal information representing an abnormal condition of the target instrument from the target instrument to a condition determination device via a network during a test operation of the target instrument instead of condition information, determining if the condition determination device can determine the target instrument as being abnormal based on the fake abnormal information, and operating the target instrument in a normal operation condition when the condition determination device can determine the target instrument as being abnormal.

摘要： In an image forming apparatus, a cleaning blade cleans residual toner adhered on the surface of an image carrier and a sound sensor collects a sound generated inside a casing of the image forming apparatus. A determining unit determines, based on the sound collected by the sound sensor, whether cleaning failure has occurred in the cleaning blade. The determining unit makes the determination based on at least intensity of a first sound component that is a sound component of a first frequency and intensity of a second sound component that is a sound component of a second frequency different from the first frequency.

摘要： An image forming apparatus includes a failure prediction unit, an image identification unit, a simulated-image generating unit, and an output unit. The failure prediction unit prepares an index value indicating a condition of the image forming apparatus based on multidimensional signal, obtained by monitoring the image forming apparatus, and compares the index value with a first threshold value to predict a failure mode of the image forming apparatus. The image identification unit identifies types of abnormal images based on the failure mode predicted by the failure prediction unit. An identified abnormal image is predicted to be appear a given time later. The simulated-image generating unit generates a simulated image of the identified abnormal image. The output unit outputs the identified abnormal image as the simulated image.

摘要： A plurality of weak discriminators output determinations results about a status of an apparatus. Weight values are individually assigned to the determination results. By performing majority vote of the weighted determination results, the status of the apparatus is determined. The determination results are displayed on a single status indicating screen such that portions corresponding to a normal status are indicated in white while portions corresponding to an anomalous status are indicated in one or more colors other than white. The areas of the portions differ from one another depending on magnitudes of weight assigned to the determination results corresponding to the portions.

摘要： An image forming apparatus is provided. The image forming apparatus includes an acquiring unit that acquires a plurality of types of operation control information of the image forming apparatus that indicate deterioration of a toner in the image forming apparatus or deterioration of a component of the image forming apparatus. An index value calculating unit calculates an index value indicating a state of the image forming apparatus based on the acquired operation control information. An abnormality judging unit judges whether the image forming apparatus abnormality has occurred and predicts an occurrence of a failure that requires maintenance of the image forming apparatus due to deterioration of the toner in the image forming apparatus or deterioration of the component of the image forming apparatus based on the index value.
