Jam history and diagnostics
DCFirst Claim
1. A method of storing and displaying information for predicting jams in a reproduction machine having a plurality of components including an operator console and touch sensitive display screen comprising the steps of:
- activating a switch to display a diagnostic and service mode on the display screen,entering a fault history mode at the operator console to display a table of machine fault histories, the fault histories including the number of actual faults and the number of amost faults of selected components,computing the rate of failure based on the number of failures and the number of almost failures relative to the number of opportunities to fail of said components,displaying the computed rate of failure for selected components on the display screen since the last service period, anddisplaying the history of previous computed rates of failure for previous service periods for selected components.

Abstract
A technique of storing and displaying machine fault information including the number of actual machine faults and the number of machine almost faults in a reproduction machine having a plurality of components and an operator console with a display screen including the steps of entering a fault history display mode at the operator console to display machine fault histories, the fault histories including the number of actual faults and the number of almost faults of selected components, computing the rate of failure of selected components based on the number of actual failures and the number of almost failures relative to the number of opportunities to fail of said components, and displaying the computed rate of failure for the selected components on the display screen.

4. A method of storing a display machine jam information including the number of actual machine faults and the number of machine almost faults in a reproduction machine having a plurality of components and an operator console with a display screen comprising the steps of:
-
entering a jam history display mode at the operator console to display machine fault histories, the fault histories including the number of actual faults and the number of almost faults of selected components, computing the rate of failure of selected components based on the number of actual failures and the number of almost failures relative to the number of opportunities to fail of said components, and displaying the computed rate of failure for the selected components on the display screen.

5. A method of determining machine fault information in a reproduction machine having a plurality of components and an operator console with display comprising the steps of:
-
entering a fault history mode at the operator console, the fault histories including the number of actual faults and the number of almost faults of selected components, and computing the rate of failure of selected components based on the number of actual failures and the number of almost failures of said components for presentation on said display.
