Fault prediction method, fault prediction system, and image forming apparatus |
摘要 |
A fault prediction method predicts a plurality of faults in a target device, and includes the steps of collecting internal information of the target device output from the target device, generating one or more criteria for defining a deviation from a normal state based on the collected internal information of the target device, incorporating the one or more criteria into a device state discriminator, identifying a deviation from a normal state in the target device according to the one or more criteria using the device state discriminator, and outputting a fault prediction as a result of the identifying step to a user. One or more of the steps are performed by a processor. |
