D135 (Japan):t5 = 350 D136 (Japan)/D135 (NA): t5 = 350 D136 (NA)/D135 (EU)/D136(EU): t5 = 350 D137 (Japan): t5 = 350 D138 (Japan)/D137 (NA)/D138 (NA)/D137 (EU)/D138 (EU): t5 = 350 Monitored at: Startup (Power-on, when a cover is closed, when fuser heater is under control)
• Causes: • IH malfunctioning • Overheating prevention device worked.
• Remedy: • Replace the thermopile. • Use with supported input voltage • Replace the IH coil/IH inverter. • Replace the unit.

• Code: SC563-00
• Description: Sensor 2: Heating Roller Front: Overheat detection (software) (T3) degrees centigrade or higher was detected for (t6) seconds consecutively. Number of times: 10 or more D135 (Japan):T3 = 250, t5 = 1 D136 (Japan)/D135 (NA): T3 = 250, t5 = 1 D136 (NA)/D135 (EU)/D136(EU): T3 = 250, t5 = 1 D137 (Japan): T3 = 250, t5 = 1 D138 (Japan)/D137 (NA)/D138 (NA)/D137 (EU)/D138 (EU): T3 = 250, t5 = 1 Monitored at: All times, though SC is not issued when temperature is not controlled (when in off mode/sleep mode, when a door, excluding the toner supply door, is open, or when the heater relay is off).
• Causes: • Triac shorted. • IOB board defective.
• Remedy: • Replace the IOB board. • Replace the unit.

• Code: SC564-00
• Description: Heating Roller Front: Overheat detection (hardware) Hardware detection of overheat condition. The heating roller front thermistor was detected as the cause.
• Causes: • IOB defective • Fuser control software running out of control • Heating roller front thermistor defective • IH inverter supplied continuously (software error or temperature sensor malfunctioning
• Remedy: • After removing the cause of the SC, Set "Fusing SC Clear" in the SP mode. • If necessary, replace: IOB/heating roller front thermistor/IH coil/IH inverter.
