6.2 SERVICE CALL
See "Appendices" for the "Error Message".
6.2.1 SUMMARY
This machine issues an SC (Service Call) code if an error occurs with the machine. The error
code can be seen with the SOM.
Make sure that you understand the following points;
1. All SCs are logged.
2. At first, always turn the main switch off and on if an SC code is displayed.
3. First, disconnect then reconnect the connectors before replacing the PCBs (if the problem
concerns electrical circuit boards).
4. First, check the mechanical load before replacing motors or sensors (if the problem concerns
a locked motor).
Fusing related SCs
To prevent damage to the machine, the main machine cannot be operated until the fusing related
SC has been reset by a service representative.

Enter "SP Mode 3" in the SOM.
Click "OK" in "Reset Fusing Unit SC" with "SP Mode 3", and then turn the main power switch off
and on.
