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.
