ABSTRACT:
Diagnostic capability is provided by setting a machine in a jam condition and using non-diagnostic dedicated circuitry. A selector switch is switched from a first predetermined number to a second predetermined number while simultaneously activating a start operation switch. Machine logic is then advanced to a diagnostic state. To exit the diagnostic state, a routine jam clearance is accomplished and the machine returns to the stand by state for normal operation.
