  • Remedy:
  • Code: C26
  • Description: Peak detection error: Lighting the exposure lamp (white reference) not detected when power turned ON.
  • Remedy: Does the exposure lamp light? (Perform the output check the test mode: 04-267)
    YES Replace the CIS unit.
    NO 1) Check if the connector of the CIS unit are disconnected. 2) Check the MAIN board if the connector (CN6) is disconnected and the harness is short circuited or open circuited. 3) Check if the conductor pattern on the MAIN board is short circuited or open circuited. 4) Replace the MAIN board. 5) Replace the CIS unit.
  • Code: C41
  • Description: Thermistor heater abnormality power-ON: Abnormality service call the thermistor detected when power turned or the temperature the fuser roller does not rise a specified period time after power turned ON.
  • Remedy: 1. Check the thermistors (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? (3) Check if the harnesses of the center, side and edge thermistors are open circuited. 2. Check the heater (1) Check if the heater is broken. (2) Check if the connector of the heater is disconnected. (3) Check if the thermostat is blown. 3. Check the MAIN board (1) Check if the connectors CN17 are disconnected. (2) Check if the conductor pattern on the MAIN board is short circuited or open circuited. (3) Replace the MAIN board. 4. Clear the status counter After repairing the matter which caused the error [C41], perform the following: (1) Turn ON the power while [0] and [8] are pressed simultaneously. (2) Key in “400”, then press [ENTER]. (3) Change the current status counter value “1” or “2” to “0”, then press [ENTER] (to cancel [C41]). (4) Turn the power OFF and then back ON. Make sure that the equipment enters the normal ready state.
  • Code: C43
  • Description: Thermistor abnormality during warming or ready status after abnormality judgment
  • Remedy:
  • Code: C44
  • Description: Heater abnormality after abnormality judgment: The temperature the fuser roller has exceeded the range control (in this case, the main switch turns OFF automatically) does not even reach the range.
  • Remedy: 1. Check the thermistors (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? (3) Check if the harnesses of the center, side and edge thermistors are open circuited. 2. Check the heater (1) Check if the heater is broken. (2) Check if the connector of the heater is disconnected. (3) Check if the thermostat is blown. 3. Check the MAIN board (1) Check if the connectors CN17 are disconnected. (2) Check if the conductor pattern on the MAIN board is short circuited or open circuited. (3) Replace the MAIN board. 4. Check the switching regulator (1) Check if the connectors CN108 are disconnected. 5. Clear the status counter Change the current status counter value (08-400) “5”, “7” or “9” to “0” for [C44], taking the same procedure as that for [C41]. * The status counter value is as follows in the following cases. Change them to “0” respectively. • The error occurred during warming-up: “5” • The error occurred after the equipment has become ready: “7” • The temperature detected by the center thermistor is 230°C or higher: “9” • The temperature detected by the side thermistor is 230°C or higher: “9” • The temperature detected by the edge thermistor is 230°C or higher: “9” only during printing.
  • Code: C45
  • Description: Thermistor abnormality during printing: Abnormality the thermistor detected during printing.
  • Remedy: 1. Check the edge thermistor (1) Check if the connector is disconnected. (2) Check if the edge thermistor is in contact with the surface of the fuser roller properly. (3) Check if the harness of the edge thermistor is open circuited. 2. Check the MAIN board (1) Check if the connector CN17 is disconnected. (2) Check if the conductor pattern on the board is short circuited or open circuited. (3) Replace the MAIN board. 3. Clear the status counter Change the current status counter value (08-400) “6” to “0”.
