Abstract: Embodiments herein maintain an unscheduled maintenance rate of a first apparatus, of a group of apparatuses, based on a history of unscheduled maintenance service calls performed on the first apparatus. Other apparatuses in the group of apparatuses have different unscheduled maintenance rates when compared to the unscheduled maintenance rate of the first apparatus. The method/system herein replaces fully used components of the first apparatus that exceed a predetermined full service life, based on usage meters of the components and replaces partially used components of the first apparatus that do not exceed the full service life, based on the usage meters.

Abstract: Systems, methods, and programs determine a fault on a device using a diagnostic agent. The systems, methods, and programs determine at least one service information associated with the fault, assigning the service bulletin to the fault, and displaying the service information associated with the fault. The systems, methods, and programs also includes identifying at least one fault in a device connected to a server, transmitting service information to the device, determining whether service information stored on the server corresponds to the fault, and assigning the corresponding service information to the fault.
