Abstract:
1. A method of ordering a queue of print jobs of a marking system including a plurality of marking engines and an electronic control system with each of said plurality of marking engines having a plurality of metrics associated therewith, said method comprising: determining, using said electronic control system, a present state value of at least one metric selected from said plurality of metrics of each marking engine, said action of determining a present state value including determining a practical end-of-life value for said at least one metric by calculating said practical end-of-life value, said action of calculating said practical end-of-life value including retrieving a theoretical end-of-life value and a multiplier from a memory and calculating said practical end-of-life value based at least in part on said theoretical end-of-life value and said multiplier; estimating an incremental depletion value for said at least one selected metric for each print job; comparing said incremental depletion value for said at least one selected metric of each print job with said present state value of said at least one selected metric of each marking engine; and, ordering said queue of print jobs based at least partially on said comparison.
