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 attractive 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 is made 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 attractive 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： A functional evaluation method and apparatus for an image forming apparatus are provided which are capable of performing functional evaluation on a plurality of functional systems such as an image formation system and a sheet transportation system in the image forming apparatus in a totalized manner for fault repair. A functional system to be subjected to functional evaluation is represented by a physical parameter model, a functional modifier configuration utilizing an FBS diagram and a functional modifier, and a functional quantity for relating the physical parameter model and the functional modifier configuration. The function manifestation level of the functional system of interest is evaluated in a state where data indicative of the state of the functional system outputted from sensors are fitted to the parameter model. If the function manifestation level is low, it is judged that a fault occurs, and a parameter is retrieved from the parameter model for improvement of the function manifestation level. Therefore, the functional evaluation of a plurality of functional systems can be performed in a totalized manner.

摘要： In an image forming apparatus according to the present invention, a software portion incorporated in the apparatus is provided with a virtual case storage portion 12, to previously create virtual cases by a virtual case compiler 16 outside of the apparatus and store the virtual cases. Fault diagnosis is made by comparing fuzzy qualitative values into which the values of sensors are converted on the basis of fuzzy membership functions with the virtual cases. If a fault is diagnosed as a result of the comparison, repair operations for repairing the fault are read out from a work script table 15. In this case, operation information for repair is stored to correspond to each of a plurality of domains into which a state space which the apparatus can take up is divided. Accordingly, it is possible to correctly read out corresponding repair operations from the work script table 15 depending on which of the domains is a domain to which the present state of the apparatus belongs. As a result, a self-repair system can be constructed as a practical built-in type system, thereby to make it possible to reduce the scale of the system related to the fault diagnosis as well as to reduce time required for the fault repair.

摘要： A sheet transportation device for use in an image forming apparatus is provided which has self-diagnosis and self-repair functions. The sheet transportation device has a sheet transportation system comprising a plurality of units (8). A control sequence for a sheet transportation operation is applied from a system body (10) to the respective units (8). The units (8) each execute the control sequence to perform the sheet transportation operation. The units (8) are each constructed so as to perform an autonomous operation. This construction allows the respective units to autonomously perform self-diagnosis and repair operations. The fault diagnosis and repair operations are performed in parallel to the sheet transportation control. Therefore, the sheet transportation device can flexibly adapt itself to an external influence such as a change in the use environment and a malfunction due to a time-related change such as the aging of components thereof. Thus, the sheet transportation device ensures a highly reliable operation and yet requires less labor for the maintenance and inspection.
