摘要:
According to the present invention, a concept of functional quantities indicative of quantified functional degrees of such lower-level functions as "clearer characters", "cleaner background", and "thicker characters", which are subordinating to a qualification-oriented function of "more beautiful characters". Characteristic patterns of functional quantities F1, F2 and F3 of the lower-level functions for physical parameters (for example, the surface potential of a photoreceptor body) are prepared. When a fault repair is implemented by changing a value of a physical parameter, a tradeoff occurs between lower-level functions which are influenced by the physical parameter. That is, taking into account the functional quantities F1, F2 and F3 of the lower-level functions, the value of the physical parameter is set so that the functional quantity of the function of "more beautiful characters" is maximized. By introducing the concept of the functional quantities indicative of the quantified functional degrees of the functions, a flexible self-repairing function can be realized, thereby optimizing a repair operation.
摘要:
The present invention makes it possible to effectively make self-repair of a fault by referencing repair analysis cases. The cases are hierarchically classified according to the fault symptom, the fault and the class, and a case suitable for a fault developed is selected to perform repair work. In applying a case, the case is corrected as required. If work succeeded by the corrected case, the corrected case is registered in the same class as a class to which the original case belongs, to make each class rich in case contents.
摘要:
The amount of degradation, converted into a fuzzy qualitative value, is found on the basis of state data sensed by sensors 1a, 1b and 1c and degradation data. The value of a parameter changed by the amount of degradation is represented by a fuzzy qualitative value. In addition, the state data is converted into a fuzzy qualitative value, and it is judged by the value whether or not a fault exists. As a result, if a fault exists, fault diagnosis is made utilizing, as an initial value the value, of the parameter changed by the amount of degradation, and the causes of the fault are specified by comparing the result of the diagnosis with the state data converted into the fuzzy qualitative value. The causes of the fault specified are repaired by operating corresponding actuators 6a, 6b and 6c. Since the causes of the fault are specified while handling the fuzzy qualitative value, the causes of the fault can be specified more precisely. Accordingly, it is possible to achieve an image forming apparatus in which autonomy is high and repair labor is reduced.
摘要:
A fixing device includes an excitation coil, a fixing member heated by electromagnetic induction by the excitation coil, a magnetic shunt alloy member, a Curie temperature of which is higher than a target fixing temperature, a determiner that determines whether the temperature of a non-sheet passing region of the fixing member is about to reach the Curie temperature, and a power controller that controls power supplied to the excitation coil. Until the determiner determines that the Curie temperature is about to be reached, the power controller performs feedback control to provide power to the excitation coil. When the determiner determines that the Curie temperature is about to be reached, the power controller switches to fixed power control so that a difference between power supplied when the Curie temperature is about to be reached and power supplied after reaching the Curie temperature falls within an allowable range.

The present invention is capable of changing the system speed quickly and highly accurately while using a CVT device with an advantage in its quietness to transmit a driving force to rotative parts.Specifically, in the case of using a sheet of thick paper as a recording sheet, the controller changes, for each of the pulleys, the distance between the pulley segments (S204) while starting up the DC motor as the driving source (S202). After that, the controller performs the feedback control on the rotation of the DC motor, based on a detection signal received from the encoder of the load shaft of the driven pulley, to achieve the target rotation speed of the load shaft (S206: NO, S207).
