3.13.4 Low voltage power supply PCB ASSY failure

3.13.5 NCU ASSY failure

User Check

• Turn the power off and on.

Step

Cause

Remedy

1

Harness connection failure of low 

voltage power supply PCB ASSY

Check the harness connection of the low 

voltage power supply PCB ASSY, and 

reconnect it.

2

Low voltage power supply PCB 

failure

Replace the low voltage power supply 

PCB ASSY. However, in the failure case 

of that the irregular power supply is 

detected, reset the irregular power supply 

detection counter following the procedure 

described in 

"3.1 Reset of Irregular Power 

Supply Detection Counter" in Chapter 4

.

3

Main PCB failure

Replace the main PCB ASSY.

CAUTION :

• The irregular power supply detection error EF occurs when there is a large fluctuation 

in the power supply voltage supplied to the machine.
In this case, if the same power supply is used, the same error might occur again even 
if the low voltage power supply PCB ASSY is replaced.

User Check

• Verify that the telephone cord is securely inserted into the right socket..

Step

Cause

Remedy

1
