failure
Replace the low-voltage power supply PCB
ASSY, and then reset the irregular power
supply detection counter.
2 Main PCB failure Replace the main PCB ASSY.
CAUTION:
• The irregular power supply detection error (error code EF00) occurs when there is a
large distortion in the power supply voltage supplied to the machine. In this case, if the
same power supply is used, the same error may occur even when the low-voltage
power supply PCB ASSY is replaced. Ask the user to review the installation
environment.
