4. TROUBLESHOOTING USING SELF-DIAG. (FULL)
4.1Overview of Self-diag. (Full) function
• If a trouble code occurs or the machine cannot operate normally due to defects of the control system hardware parts, by executing the
"Self-diag. (Full)", the defective areas on the control system hardware parts can be identified.
• The reason for troubles is broadly divided into the control system hardware trouble and the firmware trouble, and it is difficult to identify
where the trouble occurs with the trouble code.
In the "Self-diag. (Full)", two functions are provided, the one diagnoses if troubles occur on the control system hardware, and the other one
detects defective parts and displays the "error code" corresponding to the defective parts on the control panel.
NOTE
▪ Before replacing the control system hardware parts like the base board, make sure to execute the "Self-diag. (Full)".
