摘要:
An abnormality determining apparatus is capable of avoiding mistaken determinations due to the normal value of information obtained by an information obtaining unit differing according to the content of specific information such as the operating mode setting, and deterioration of the determination precision due to a change in the user of a detection subject. The abnormality determining apparatus comprises an information storage unit for storing normal index information serving as an index of a normal state of the detection subject, an information obtaining unit for obtaining a plurality of types of information, and an abnormality determining unit for determining the presence of an abnormality in the detection subject on the basis of the normal index information stored in the information storage unit, and the information obtained by the information obtaining unit. The information storage unit stores a plurality of normal index information having different values. The abnormality determining unit selects, at a predetermined timing, normal index information to be used to determine the presence of an abnormality in the detection subject from the plurality of normal index information.

A time point at which a predetermined period elapses since the start of use of a copying machine as a detection subject after factory shipment or repair is obtained. Pieces of set information, which are combinations of various types of information until the time point is reached are sequentially stored to construct a normal set information group. After the time point is reached, presence of abnormality in the copying machine is determined based on the normal set information group and the various types of information obtained.
摘要:
An apparatus, method, system, computer program, and product, each capable of detecting a state of an apparatus. The apparatus includes a plurality of devices. When at least one of the plurality of devices is determined to be in a first state, a second state of at least one of the plurality of devices is determined. When a state of the apparatus is determined to be in the first state, the second state of another apparatus is determined.

摘要:
An image forming apparatus is capable of specifying the type of an occurring abnormality to a certain extent while avoiding the increasingly complicated control that is caused when a plurality of abnormalities is detected individually according to the presence of their respective causes. A normal group data set, which is a collection of normal value combinations relating to grouped information constituted by a plurality of information of differing types, is stored in RAM or ROM serving as information storage device of a control unit. At least two or more sets of grouped information, including first grouped information constituted by a plurality of different types of information, and second grouped information constituted by a plurality of information in a different combination to that of the first grouped information, are obtained from the RAM, the ROM, various sensors, and an operation display unit.

摘要:
A recording medium conveyance failure occurrence predicting apparatus predicts an occurrence of a conveyance failure of a recording medium conveyed in a conveyance path in an image forming apparatus including a recording medium conveyance member that conveys the recording medium while moving and contacting the recording medium, and a separation portion where the recording medium is separated from the recording medium conveyance member. The recording medium conveyance failure occurrence predicting apparatus includes a recording medium abnormal separation detecting unit that detects an abnormal separation of the recording medium from the recording medium conveyance member, and a determining unit that predicts an occurrence of a conveyance failure of the recording medium in the separation portion based on a detection result of the recording medium abnormal separation detecting unit.
