Boot System Error Diagnosis
Boot Method
1) Turn ON the Main Power Supply Switch while pressing the Control Panel Energy Saver Switch.
Note:
At the time of high-speed start ON, you cannot use it.
Perform OFF/ON of the breaker once.
2) Right after the Main Power Supply Lamp lights up once, it lights out instantly, and diagnosis starts.
(When the Main Power Supply Lamp lights out, you can release your finger from the Control Panel Switch.)
Diagnosis Time
Diagnosis is completed in approx. 1 minuites.
<When the diagnosis result is normal>
After the Main Power Supply Lamp repeatedly lights out 4 times, it lights up and the diagnosis is completed.
After completion of the diagnosis, this machine executes normal boot sequence.
<When an error is detected by diagnosis>
The Main Power Supply Lamp repeats high-speed blinking after completion of a check in which an error is detected. (See *1.)
For example, when an error is detected in Check 2, the Main Power Supply Lamp lights out twice and repeats high-speed blinking (ON/OFF in 0.3 seconds interval).
When an error is detected, be sure to count the number of times the Main Power Supply Lamp lights out.
For detailed results, see “Error Diagnosis”.
*1: When an error is detected, there is a possibility that the Main Power Supply Lamp may not perform high-speed blinking but perform other operation (continuous light-up, light-out). In this case, remove and then install the Main Controller PCB 1.
If the error is not resolved, execute the remedy of the Check No. which is not completed normally. (For details, see “Error Diagnosis”.)
*2: Although diagnosis time for Check 3, and Check 4 is longer than that of other Checks, it is correct operation.
