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.
In a reproduction machine having a plurality of discrete operating components cooperable with one another to produce images on copy sheets and including an operator console having an alphanumeric display and a scrolling switch and a controller with a nonvolatile memory for storing indications of the operation of selected operating components, the operating components being grouped into categories, each category having subcomponents for monitoring, the method of monitoring the operation of a selected operating component including the steps of entering a display mode to display a diagnostic menu, scrolling the categories of reproduction machine components on the display in response to the activation of said scrolling switch, selecting a category of machine components, scrolling a set of subcomponents on the alphanumeric display within the said first selected category in response to the activation of said scrolling switch, and selecting one of said subcomponents for monitoring.
