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.

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： In a digital PLL system, instead of measuring a binarized playback RF signal with a high frequency clock, pulse-length data is generated by using N phase clocks (for example, 16 phase clocks). The pulse-length data is then run-length counted with a virtual channel clock so as to extract data. In this digital PLL system, the number of changing points of an asynchronous signal during an interval between adjacent clocks of the N phase clocks is detected so as to determine phase errors from the detected number of changing points. Phase errors are also determined from the timing relationship between changing points of a signal synchronized with the N phase clocks and each clock of the N phase clocks.
