摘要： A fault prediction method predicts a plurality of faults in a target device (100), and includes the steps of collecting internal information of the target device (100) output from the target device (100), generating one or more criteria for defining a deviation from a normal state based on the collected internal information of the target device (100), incorporating the one or more criteria into a device state discriminator (105), identifying a deviation from a normal state in the target device (100) according to the one or more criteria using the device state discriminator (105), 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.
Yet, an image forming apparatus provides for an internal information collector (101) and for an input receiver (109,120) to incorporate criteria defining a deviation from a normal state in the image forming apparatus, to a state discriminator (108) and output interface (106).

摘要： When a device has a plurality of functions and setting items ("1."-"6."), a particular function and a particular setting item are selected from among a plurality of those functions and setting items ("1."-"6."). A menu having a tree structure is used in this selection by specifying a position in the tree structure so as to set the function and the setting item. The tree structure of the menu classifies the functions and the setting items.
