4.8 DIAGNOSTIC TEST MODES
4.8.1 OVERVIEW
This machine has two types of diagnostic test mode.
•
Power-up diagnostics: Done every time the machine is switched on
•
Detailed diagnostics: Done after entering the detailed diagnostic mode
4.8.2 POWER-UP DIAGNOSTIC MODE
This is automatically done to check system integrity whenever the machine is
powered up.
If the Power LED blinks during this test, the test is proceeding without problems.
If the Power LED does not blink during the test, it means that a fatal error has
occurred. If the machine detects an error, the machine displays an SC code (e.g.
SC 2100) on the operation panel, turns off the Power LED, blinks the Error LED,
and stops system booting.
If the error is for an optional device (if one of the following SCs is displayed), switch
off the power, disconnect the defective optional device, then turn the power back
on. The machine will restart.
