Abstract
A fault clearance and recovery operation in an electronic reprographic system comprises storing in memory clearance and recovery instructions for specific system faults, monitoring the system for fault occurrence and accessing displaying the stored instructions upon detection of a fault occurrence. Faults having similar recovery features are classified into buckets to facilitate the clearance and recovery operations.
Claims21
A method for clearance and recovery of faults in an electronic reprographic system, comprising the steps of:
- storing in memory clearance and recovery instructions for specific system faults;
- monitoring the system for fault occurrence during a normal system operating mode;
- detecting at least two fault occurrences during the normal system operating mode;
- grouping the at least two detected fault occurrences into at least one fault bucket, each fault bucket having a unique set of specific clearance and recovery instructions corresponding to the fault bucket and each fault bucket comprising a collection of faults which require the same unique set of specific clearance and recovery instructions corresponding to the fault bucket;
- automatically accessing, based on at least one fault bucket, at least one unique set of specific clearance and recovery instructions corresponding to the at least one fault bucket;
- automatically initiating clearance of and recovery from the at least two fault occurrences using the accessed at least one unique set of specific clearance and recovery instructions without requiring an operator to assist in restoring the system to the normal system operating mode;
- and
- automatically displaying appropriate ones of the accessed clearance and recovery instructions corresponding to the at least one fault bucket when automatic recovery from the at least two fault occurrences fails to restore the system to the normal system operating mode, the appropriate ones of the accessed clearance and recovery instructions enabling an operator to manually initiate and perform clearance and recovery.

An apparatus for clearance and recovery of faults in an electronic reprographic system, comprising:
- storage means for storing in memory clearance and recovery instructions for specific system faults;
- monitoring means for monitoring the system for at least two fault occurrences during a normal system operating mode, and for detecting at least two fault occurrences;
- grouping means for grouping the at least two detected fault occurrences into at least one fault bucket, each fault bucket having a unique set of specific clearance and recovery instructions corresponding to the fault bucket and each fault bucket comprising a collection of faults which require the same unique set of specific clearance and recovery instructions corresponding to the fault bucket;
- accessing means for automatically accessing, based on at least one fault bucket, at least one unique set of specific clearance and recovery instructions corresponding to the at least one fault bucket;
- automatic clearance and recovery means for automatically initiating clearance of and recovery from the at least two fault occurrences using the accessed at least one unique set of specific clearance and recovery instructions without requiring an operator to assist in restoring the system to the normal system operating mode;
- and
- display means for automatically displaying appropriate ones of the accessed clearance and recovery instructions corresponding to the at least one fault bucket when automatic recovery fails to restore the system to the normal system operating mode, the displaying of the appropriate ones of the accessed clearance and recovery instructions enabling an operator to manually initiate and perform clearance and recovery.
