is used for an occasion like repair. If this function is ignored when a new supply main PCB is
used, software like MPS application and BrAdmin tool are not operable. It may also be
exposed to information leakage risk due to the compromised security. When a new supply
main PCB is used, always implement this function after the repair. This machine does not
have a function to return the machine from the factory shipping state to the state prior to the
factory shipment.
