CPU OVERRUN MONITOR FUNCTION

• CPU Overrun Monitor Function (Watchdog Function)
The watchdog function is a self-monitoring function that determines whether any of the
CPUs mounted on the control board overrun.
• If this function detects that a CPU overruns, the copier automatically resets the CPU,
thereby restarting the logic circuit and mechanism.
• Even if a copier CPU operates erratically due to electrical noise, therefore, the copier is
able to recover from the faulty condition so that the number of visits made by the Tech.
Rep. for CPU overrun can be minimized.
• Processing performed during watchdog function:
If a faulty condition is detected, the copier resets the CPU and performs a restart
sequence. Since this sequence of operations is performed even during a copy cycle, the
copier detects a sheet or sheets of paper left inside it as a misfeed while it is being
restarted.
