Replace the carriage home position sensor. 3. Replace the SLG board. NO The carriages are stopped at the home position and do not move. 1. Check if the connector pins are disconnected and the harnesses are short circuited or open circuited. 2. Check if the conductor pattern on the SLG board is short circuited or open circuited. 3. Replace the SLG board.

• Code: C3D0
• Description: EPU board memory overwriting error: The overwriting of the EPU board memory fails.
• Remedy: (1) Check if the process unit is properly installed, and check if the connector pins that are connected to the equipment are disconnected or have any abnormality such as deformation. (2) Check if the harness connected to the connector J451 on the EPU board has any abnormality. (3) Replace the EPU memory board. (4) Replace the LGC board.

• Code: C3D1
• Description: EPU board memory new parts detection error: The EPU board detects the process unit as a new unit when the equipment is started in the normal mode.
• Remedy: (1) If the process unit has been replaced with a new one before the equipment is started, turn the power OFF and then back ON in the EPU replacement mode ([7] + [START]). (2) If the process unit has not been replaced, check the following. (3) Check if the process unit is properly installed, and check if the connector pins that are connected to the equipment are disconnected or have any abnormality such as deformation. (4) Check if the harness connected to the connector J451 on the EPU board has any abnormality. (5) Replace the EPU memory board. (6) Replace the LGC board.

• Code: C3D2
• Description: EPU board memory old parts detection error: The EPU board cannot detect the new process unit when the equipment is started in the EPU replacement mode ([7] + [START]).
• Remedy: (1) Check if the process unit is a new one. If it is a new one, check the following: (2) Check if the process unit is properly installed, and check if the connector pins that are connected to the equipment are disconnected or have any abnormality such as deformation. (3) Check if the harness connected to the connector J451 on the EPU board has any abnormality. (4) Replace the EPU memory board. (5) Replace the LGC board.

• Code: C410
• Description: Thermistor or heater abnormality at power-ON: Abnormality of service call the thermistor is detected when power is turned ON or the temperature of the fuser roller does not rise in a specified period of time after power is turned ON.
• Remedy: (1) Check if the connectors are disconnected. (2) Check if the center, side and edge thermistors are in contact with the surface of the fuser roller properly?
