A computer implemented method for determining the end of life condition for a replaceable unit (such as an automatic handler roll, a fuser module or a paper feed roll), associated with a multifunction device, comprising a counter associated with the multifunction device maintaining a running count of operations for the unit. Once the number of performed operations of the replaceable unit reaches a given percentage of the expected life of that unit (218), an analysis is performed on a running history of the fault codes. Once the number of fault codes attributable to any given replaceable unit meets or exceeds a predetermined level, such as a percentage of the running history, a notification is generated indicating a need to replace the replaceable unit. |
