Summary
This machine issues an SC (Service Call) code if an error occurs with the machine. The error code can be
seen on the operation panel.
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).

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 the engine maintenance mode.
Press "O.K" in "Fuser SC Reset" with engine maintenance mode, and then turn the main power switch off
