Check with the item of “STATUS” on the “Product information
(INFORMATION)” screen.
When [Other] menu is pressed, the “INFORMATION” screen is
displayed. Check with the “STATUS” item on the screen.
It takes some time necessary for judgment of a temperature
abnormality and a hardware abnormality as shown below:
*Temperature abnormality:
Min. 2 minutes (Exceeding the threshold value 3 times
continuously in the interval of 1 minute).
*Hardware abnormality:
Min. 18 seconds (Exceeding the threshold value 4 times
continuously in the interval of 6 seconds).
Though, therefore, the threshold value is exceeded on the
"HARDWARE CHECK" screen of SERVICE MANU 2 or in the
periodic send/test mail, "OK" may be displayed.
In addition, when "NG" judgment is made once, "NG" state is
maintained until the power is turned OFF/ON. Even if, therefore,
the target value is reduced below the threshold value, the
judgment may be "NG" with a normal value.
