ABSTRACT:
The present invention is a reproduction machine having a non-volatile memory for storing indications of machine consumable usage such as photoreceptor, exposure lamp and developer, and an alphanumeric display for displaying indications of such usage. In operation, a menu of categories of machine components is first scrolled on the alphanumeric display. Scrolling is provided by repetitive actuation of a scrolling switch. Having selected a desired category of components to be monitored by appropriate keyboard entry, the subcomponents of the selected category can be scrolled on the display. In this manner, the status of various consumables can be monitored and appropriate instructions displayed for replacement. In another feature, the same information on the alphanumeric display can be remotely transmitted.
