Controller System Error Diagnosis
Boot Method
1) Turn ON the Main Power Supply Switch while pressing the numeric keys ‘2’ and ‘4’ simultaneously.
2) Keep pressing the numeric keys (for approx. 20 seconds) until the following screen appears on the Control Panel.
NOTE:
When this tool is not installed correctly, the following regular screen is displayed.
In this case, perform the following remedy.
Turn OFF the Main Power Supply Switch again, and execute step 1 and 2 shown above.
If this tool still does not boot, it means that BCT is deleted. So, install BCT.
If BCT is not installed correctly, “--.--” is displayed in Service
Mode (COPIER>DISPLAY>VERSION>BCT) in the main body.
Diagnosis Time
Diagnosis is completed in approx. 3 minutes.
The result is displayed on the Control Panel.
<When the diagnosis result is normal>
<When an error is detected by diagnosis>
Detailed information is displayed under the judgment result. In detailed information, the name of the test where an error was detected is indicated.
<When an error is detected by diagnosis>
Detailed information is displayed under the judgment result. In detailed information, the name of the test where an error was detected is indicated.
<How to view the error result>
The following screen is an enlarged view of the detailed information indicated above.
Explanation of the detailed error information is described.
[no] means that optional PCBs are not mounted.
When [no] is displayed although an optional PCB is mounted, it means that an error has been occurring.
[NG] means that an error occurred to PCBs mounted as standard.
<Controller System Error Diagnosis Table>
The error locations are identified according to the following table.
