(5) Check if the transfer belt release detection sensor and transfer belt contact detection sensor is working properly. (6) Replace the transfer belt cam motor. (7) Replace the LGC board.
  • Code: C411
  • Description: Thermistor/heater abnormality at power-ON: Thermistor abnormality is detected at power-ON or the fuser roller temperature does not rise within a specified period of time after power-ON.
  • Remedy: 1.Check the power voltage (1) Check if the power voltage is normal.(Is the voltage during the operation ±10% of the rated voltage?) 2.Check the thermistors (1) Check if the connectors are disconnected. (2) Check if the center and side thermistors (front, rear) are in contact with the surface of the fuser roller properly? (3) Check if the harnesses of the center and side thermistors (front, rear) are open circuited. 3. Check the heater (1) Check if the IH coil is broken. (2) Check if the connector of the IH coil is disconnected. (3) Check if the thermostat is blown. (4) Check if the connectors on the IH control board are disconnected (AC input connector and LGC I/F connectors CN455). (5) Check if the IH control board is abnormal. • Replace the IH control board. 4. Check the LGC board (1) Check if the connectors CN332,CN334 are disconnected. (2) Check if the conductor pattern on the LGC board is short circuited or open circuited. (3) Replace the LGC board. 5. Clear the status counter After repairing the matter which caused the error [C411/C412], perform the following: (1) Turn ON the power while [0] and [8] are pressed simultaneously. (2) Key in "400", then press [START]. (3) Change the current status counter value "1" or "2" to "0", then press [ENTER] or [INTERRUPT] (to cancel [C411/C412]). (4) Turn the power OFF and then back ON. Make sure that the equipment enters the normal ready state.
