Abstract
A control system for a laser printer and other image recorders stores history data including the number of prints produced by a photoconductive element and occurrences of various kinds of failures, and displays the history data at suitable timings. The control system, therefore, displays data which may be referenced in the event of a failure of the image recorder.
