Abstract
There is provided a printing system with a first service and a second service. The first service and the second service are controlled by a system controller, and are activated selectively by the system controller in a first mode. The printing system includes a diagnostic subsystem including a first diagnostic routine for performing a diagnostic function relative to the first service and a second diagnostic routine for performing a diagnostic function relative to the second service. The printing system further includes a diagnostic system controller that communicates with the system controller and is activated selectively by the system controller in a second mode. The first diagnostic routine and the second diagnostic routine are activated, for concurrent operation thereof, when the diagnostic system controller determines that a preselected condition has been met.
