Abstract

A method of scheduling service events for a hard copy output engine includes (i) estimating when a service event is likely to occur, (ii) estimating, from a record of past usage, when peak usage is likely to occur, (iii) determining when the service event estimate is contemporaneous with the peak usage estimate and (iv) executing a predetermined protocol when determining is indicative of contemporaneous estimates.

Claims

1. A method of scheduling service events for a hard copy output engine comprising:

estimating when a service event is likely to occur;

estimating, from a record of past usage, when peak usage of the hard copy output engine is likely to occur;

determining when the service event estimate is contemporaneous with the peak usage estimate; and

executing a predetermined protocol when determining is indicative of contemporaneous estimates.

2. The method of claim 1, wherein estimating when a service event is likely to occur includes determining when a pigmentation material supply is likely to be exhausted and executing comprises transmitting a warning when it is determined that the service event estimate is contemporaneous with the peak usage estimate.

3. The method of claim 1, wherein estimating when a service event is likely to occur includes determining when a self-calibration event is likely to occur.

4. The method of claim 1, wherein:

estimating when a service event is likely to occur includes determining when a self-calibration event is likely to occur; and

executing comprises initiating the self-calibration event prior to a time when the peak usage is estimated to occur.

5. The method of claim 1, wherein estimating when peak usage is likely to occur comprises estimating based in part on historical page count per unit time data.

6. The method of claim 1, wherein estimating when a service event is likely to occur includes estimating based in part on historical pixel count data.

7. The method of claim 1, wherein estimating when a service event is likely to occur is initiated by a pigmentation material level dropping below a user-settable threshold.

8. A method of scheduling service events for a hard copy output engine comprising:

estimating, using a record of past usage of the hard copy output engine, when a service event is likely to occur; and

executing, by a processor contained in the hard copy output engine, a predetermined protocol at a time based on estimated hard copy output engine usage and estimated lead time for servicing the service event.

9. The method of claim 8, wherein estimating when a service event is likely to occur includes determining when a pigmentation material supply is likely to be exhausted and executing comprises transmitting a message to initiate an order for the service event.

10. The method of claim 8, wherein:

estimating when a service event is likely to occur includes determining when a pigmentation material supply is likely to be exhausted, the method further comprising;

estimating, from a record of past usage, when peak usage of the hard copy output engine is likely to occur;

determining when the service event estimate is contemporaneous with the peak usage estimate; and

executing comprises initiating replacement of the pigmentation material supply prior to or after a time when the peak usage is estimated to occur.

11. The method of claim 10, wherein estimating when peak usage is likely to occur comprises estimating based in part on historical page count per unit time data.

12. The method of claim 10, wherein estimating when a service event is likely to occur includes estimating based in part on historical pixel count data.

13. The method of claim 8, wherein estimating when a service event is likely to occur is initiated by a pigmentation material level dropping below a user-settable threshold.
