SELF-DIAGNOSTIC AND SELF-REPAIRING SYSTEM FOR IMAGE FORMING DEVICE

摘要

PURPOSE:To contrive the acceleration in self-restoration by correcting the application condition of a 1st work in a working script when the 1st work is failed, retrieving the working script of a failure cause and executing 1 2nd work capable of turning the current state of a device to a state capable of applying the 1st work after correcting the 1st application condition. CONSTITUTION:A case detecting means retrieves the cases stored in a case storing means 17 and detects the case of a failure state and a failure cause diagnosed by a failure diagnosing mean 12. At the time of deciding the discrepancy of a consequent when the 1st work corresponding to the working index of the case to be applied is executed, necessary correction is applied to the contents and working script of the case and additional processing is executed. The necessary correction means to additionally insert the 2nd work or correct the precedent of the work so that the condition of precedent coincidence can be satisfied when a prescribed state can be obtained at the time of executing the work initially included in the case. Thus, the self-restoration can be executed.
