Abstract
The present invention relates to providing supplemental counts or “clicks” to account for recovery conditions in a document processing system. The application of recovery counts combined with the system cycle count when suitably summed will provide superior measure of the wear for a replaceable element as well as improved indication for the determination of the end of life of a replaceable element in that system. In this manner the more timely service or substitution for that replaceable element in the system can be provided, thereby allowing costs and service down-time to be minimized.
Claims26
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.
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.
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.
