In reprographic systems having advanced diagnostic capability, it is generally known to enable a service technician access to subroutines within the diagnostic programs of the system for troubleshooting purposes. Access to these subroutines is enabled by utilizing the control panel of the reprographic system. More specifically, the service technician is required to enter codes, via keystroke sequences on the control panel, to activate or read the status of system components. One system incorporating this technique is the Xerox 1090 copier, where a 5 digit numeric entry was required for each diagnostic code. This method proved to be not only cumbersome and time consuming, but prone to error in entry of the codes.
