Abstract
A copy production machine, or other semiautomatic operator-involved machine, logs operations data and error data during normal operations into a nonvolatile store. Logging is categorized for facilitating diagnostics and maintenance of the machine. During a maintenance mode, log scanning methods enable efficient retrieval of the logged data via a keyboard entry system plus manual actuation of other switches used for other purposes during the normal copy production.
