Claims
- 1. A method for assessing an end of life determination for a replaceable element in a system comprising:accepting a system cycle as a nominal count; monitoring the system for a recovery condition; providing a recovery count in the event of the recovery condition; and, summing the nominal count and the recovery count into a supplemental diagnostic counter.
- 2. The method of claim 1 wherein the system is a document processing system.
- 3. The method of claim 2 wherein the summing step further comprises summing a startup count for job startup conditions.
- 4. The method of claim 2 wherein the summing step further comprises summing a cycle-down count for job end conditions.
- 5. The method of claim 2 wherein the recovery condition is recovering from system power loss.
- 6. The method of claim 2 wherein the recovery condition is recovering from a paper jam.
- 7. The method of claim 2 wherein the supplemental diagnostic counter resides in the system.
- 8. The method of claim 2 wherein the replaceable element item has a customer replaceable unit monitor and the supplemental diagnostic counter resides in the customer replaceable unit monitor.
- 9. A method for assessing end of life determinations for high frequency service items in a document processing system comprising:accepting a document processing system cycle as a nominal count; applying at least one weighting factor to the nominal count to yield at least one weighted count; monitoring the system for a recovery condition; providing a recovery count in the event of the recovery condition; and, summing the one or more weighted counts and the recovery count into a supplemental diagnostic counter.
- 10. The method of claim 9 wherein the high frequency service item is a customer replaceable unit.
- 11. The method of claim 10 wherein customer replaceable unit has a customer replaceable unit monitor.
- 12. The method of claim 11 wherein the supplemental diagnostic counter resides in the document processing system.
- 13. The method of claim 11 wherein the supplemental diagnostic counter resides in the customer replaceable unit monitor.
- 14. The method of claim 13 wherein the at least one weighting factor further comprises a weighting for environmental factors.
- 15. The method of claim 13 wherein the at least one weighting factor further comprises a weighting for media type.
- 16. The method of claim 13 wherein the at least one weighting factor further comprises a weighting for job type.
- 17. The method of claim 13 wherein the at least one weighting factor further comprises a weighting for job run length.
- 18. A method for assessing end of life determinations for a high frequency service item in a document processing system comprising:incrementing a nominal counter by a nominal count for each cycle of the document processing system; applying at least one weighting factor to the nominal count to yield a weighted count; monitoring the system for a recovery condition; providing a recovery count in the event of the recovery condition; monitoring the system for a startup condition; providing a startup count in the event of the startup condition; monitoring the system for a cycle-down condition; providing a cycle-down count in the event of the cycle-down condition; and, summing the nominal count, the weighted count, the recovery count, the startup count and the cycle-down count into a supplemental diagnostic counter.
- 19. The method of claim 18 wherein the high frequency service item is a customer replaceable unit.
- 20. The method of claim 19 wherein customer replaceable unit has a customer replaceable unit monitor.
- 21. The method of claim 20 wherein the supplemental diagnostic counter resides in the document processing system.
- 22. The method of claim 20 wherein the supplemental diagnostic counter resides in the customer replaceable unit monitor.
- 23. The method of claim 22 wherein the at least one weighting factor further comprises a weighting for environmental factors.
- 24. The method of claim 22 wherein the at least one weighting factor further comprises a weighting for media type.
- 25. The method of claim 22 wherein the at least one weighting factor further comprises a weighting for job type.
- 26. The method of claim 22 wherein the at least one weighting factor further comprises a weighting for job run length.
