Reliability model based copy count correction with self modification during system recovery for predictive diagnostics

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;
• monitoring the recovery condition for type of recovery;
• providing a recovery count modified by the type of recovery 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;
• monitoring the recovery condition for type of recovery;
• providing a recovery count modified by the type of recovery 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.
