5. WATCHDOG FUNCTION (CPU OVERRUN MONITOR)
• The watchdog function, or CPU overrun monitor function, monitors whether any of the
CPUs mounted in the copier overruns.
• If the function detects that a CPU overruns, the copier automatically resets the CPU,
thereby restarting the logic circuit and mechanism.
5-1. Watchdog Function Post-Processing
The following processing is performed if a faulty condition is detected in the CPU.
When the copier CPU is found faulty:
• All CPUs are reset and the system is restarted.
• If the CPU is found faulty during a copy cycle, the system attempts to feed all sheets of
paper out of the copier before restarting. (If paper is left inside the copier, the copier
detects it as a misfeed as it is restarted.)
