DIP Switch Settings
When replacing the BCU board with a new one that has DIP switch on it, check and see if the old board also
has a DIP switch. If there is no DIP switch on the old board, keep the DIP switch on the new board switched
OFF. If there is a DIP switch on the old board, the DIP switch setting on the new BCU board must be the
same as on the old board. Otherwise, problems will occur. Please refer to the following table. The default
setting of the DIP switch on the service part is switched OFF.

The fusing unit is driven as usual. However, the
machine detects that a fusing clutch has been
installed. This results in the PM counter from the
fusing unit and oil supply unit to stop counting as
the machine does not send the signal to turn the
clutch on (at the process control self check, etc,
as mentioned above).
