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.

An image forming apparatus includes an acquiring unit that acquires a plurality of types of operation control information of the image forming apparatus; an index value calculating unit that calculates an index value indicating a state of the image forming apparatus based on the acquired operation control information; an abnormality judging unit that judges whether the image forming apparatus abnormality has occurred and predicts an occurrence of a failure based on the index value; and a detection pattern position detecting unit that detects a position of a detection pattern on an image carrier carrying a toner image. The detection pattern is formed on the image carrier carrying the toner image. The detection pattern position detecting unit detects the position of the detection pattern formed on the image carrier. The index value calculating unit uses information based on position detection data as the operation control information of the image forming apparatus.
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.

An image forming apparatus includes toner image forming devices for forming toner images of a plurality of mutually different colors, a toner image carrying member for carrying thereon the toner images of the plurality of colors to be transferred onto a recording medium at one time, an adhesion amount detection device for detecting a toner adhesion amount of each of the toner images, and a failure determination device for determining the presence or absence of a sign of failure in the toner image forming devices. The failure determination device determines the presence or absence of the sign of failure in one of the toner image forming devices on the basis of information based on adhesion amount detection results obtained through detection by the adhesion amount detection device of toner adhesion amounts of toner images formed on the toner image carrying member by the other toner image forming devices.
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.
