ITEMS TO BE CHECKED

HOW TO SOLVE

Operation panel does
not operate.

LF motor does not
operate

SCAN motor does not
operate

• Check the power switch.

• Check the power supply.

• Check the driver IC defect.

• Check the download mode.

• Check the harness contact.

• Check 7-segment LED.

• Check the key contacts.

• Otherwise

• Check the harness contact.

• Check the control signals of U44-139-144

in Main PBA.

• Check the motor signals of U2-1, 19 and

U3-1, 19 in Driver PBA.

• Check the harness contact.

• Check the control signals of U12-112-119

in Main PBA.

• Check the motor signals of U9-1, 19 and

U10-1, 19 in Driver PBA.

• Check the switch operation.

- If the switch on, U12-96 = 5V
If the switch is defect, replace it.

• Check the fuse. If the fuse is defected, replace it

with 250V/3A.

• Check the output voltage in power alone.

- CON1-1 = 5V +5%
- CON1-2 = GND 5V
- CON1-3 = 12V +2%
- CON1-4 = GND 12V
- CON1-5 = GND 30V
- CON1-6 = 30V +5%

• The following driver ICs defect can cause power

down. Remove a IC and check the power on.
- U37, U39, U25, and U26 in Main PBA
- U2, U3, U4, U9, and U10 in Driver PBA

• Download the firmware of recent version, and

check the system initial.

• Check CN10 and CN14 contact in Main PBA

whether each connection is tight.

• Replace the part or OPE PBA.

• Check the mechanical defect, and replace the

front cover.

• Replace the Main PBA.

• Check CN5 contact in Main PBA, CN2 contact in

Driver PBA, and CN5, 8 in Driver PBA whether
each connection is tight.

• If these CMOS signals are defective when the

other functions normal, replace the Main PBA.

• If these 30V signals are defective when the other

functions normal, replace the Driver PBA.

• Check CN5 contact in Main PBA, CN2 contact in

Driver PBA, and CN5, 7 in Driver PBA whether
each connection in tight.

• If these CMOS signals are defective when the

other functions normal, replace the Main PBA.

• If these 30V signals are defective when the other

functions normal, replace the Driver PBA.
