Abstract

Error conditions in a machine are monitored by conventional data processing equipment to indicate the need for repair actions or preventive maintenance if predetermined marginal conditions are surpassed or for machine shutdown, under some conditions. While the procedure is useful for a variety of machines, it is described below in the environment of a copier or printer-type product. To implement the process, the console of a conventional copier or xerographic printer is augmented by inclusion of an "Inform C.E." light on the console. This light is actuated when marginal failure conditions are detected in the machine.

Marginal Failure Monitoring for Machine Maintenance and Repair

Error conditions in a machine are monitored by conventional data processing equipment to indicate the need for repair actions or preventive maintenance if predetermined marginal conditions are surpassed or for machine shutdown, under some conditions. While the procedure is useful for a variety of machines, it is described below in the environment of a copier or printer-type product. To implement the process, the console of a conventional copier or xerographic printer is augmented by inclusion of an "Inform C.E." light on the console. This light is actuated when marginal failure conditions are detected in the machine. For instance, the number of paper jams in original document feeds, copy sheet feeds, or the like, are monitored and accumulation of a number in a conventional counter of such jams in excess of a predetermined functional criteria indicates repair or maintenance action is required. Logical detection of this condition results in actuation of the aforementioned light. When the predetermined number of failures occur, such as five paper jams for 10,000 copies, the light is turned on, whereas the exceeding of a second set of failure interval criteria is used to shut the machine down and force repair action. The repair action counter is reset or updated through machine copy counts. This type of tracking is used for paper path jams, document feed of originals between misfeeds (OBM), toner box full monitored maintenance (MM) interval, light photoconductor errors, and the like. Monitoring, as described at appropriate and proper intervals, yields machine performance improvements by allowing corrective action before machine-stop- type failures. In addition, the criteria is changeable, as desired. The process allows overriding or reduction of criteria where desirable, such as when inferior supplies are utilized. The process is shown in the flowchart. This...
