Abstract

A display for use in conjunction with a copier. The disclosed display comprises two microprocessors for controllably displaying information on a display panel of a xerographic copier. A first microprocessor is primarily responsible for energizing alphanumeric elements to either send messages to the copier user or to prompt the user to interact with the copier. A second display is a liquid crystal display wherein selectively energizable liquid crystal elements corresponding to copier components can be rendered visible under the control of the second microprocessor. An overlay pattern can be placed above the liquid crystal display to present to the user in outline form the copier architecture with which he is interacting. This overlay can be changed as the copier configuration is changed. The electronics for controlling the display of alphanumeric allows the utilization of different fonts and/or different languages. This flexibility allows the copier to prompt, and/or display information regarding copier status in various languages without a redesign of the display unit.
