  • Fault-based unit replacement
    Patent number: 8819498
    Abstract: A method and system are disclosed for determining the end of life condition for a replaceable unit, which may be associated with a multifunction device, and have a useful life expectancy based upon a number of operations. A counter associated with the multifunction device maintains 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, 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.
    Type: Grant

  • Reserve life run-on feature for customer replaceable units
    Patent number: 7526215
    Abstract: A printer includes at least one replaceable module which is removable from the printer. A processor discontinues an operation of the printer when the processor determines that an end of life value for the replaceable module is reached unless an appropriate identifier is input which allows the operation of the printer to continue beyond the end of life value. The identifier may be provided by a supplier at the end of life point, provided that an order for a replacement module is received.
