Description: Toner supply feed lock (01: Bk, 02: C, 03: M, 04: Y) Under the condition that the Toner Cartridge has not reached the end, an error that no toner is supplied has been detected over n times in succession. n: The value was set at SP3-131-015.
Causes: • Disconnected or broken Toner Supply Solenoid. (Failed to open the toner supply shutter) • Disconnection of Toner Supply Clutch • Failed PCDU. (Toner leak) • Toner clogging
Remedy: • Check the connector connection or check for broken wire. • Replace the Toner Supply Solenoid • Replace the PCDU • Replace the Toner Cartridge.
Code: SC364-01 ... SC364-04
Description: Toner End Sensor output count error (01: Bk, 02: C, 03: M, 04: Y) The output count from the Toner End Sensor indicates an average of 0.
Causes: - Bad connector contact or connector disconnected/wire broken - Failed TE Sensor - LED Head mounting error (incorrect calibration of TE Sensor)
Remedy: - Turn the main power of the printer OFF and then ON - Check the connector connection or check for broken wire. - Replace the LED Head. - Replace the TE sensor (using the same troubleshooting procedure as for LED).
Code: SC365-01 ... SC365-04
Description: Toner End Sensor upper limit sensor error (01: Bk, 02: C, 03: M, 04: Y) The Toner End Sensor still indicates that the remaining amount of toner is at the "upper limit", although 255 g or more toner has been consumed.
Causes: - Stained TE Sensor surface - Failed TE Sensor
Remedy: • Turn the main power of the printer OFF and then ON. • Check the connector connection. • Clean/replace the sensor (using the same troubleshooting procedure as for LED).
Code: SC370-01
Description: TM(ID) Sensor calibration error (Right)* The specular light output voltage (Vsg_reg) of the Right TM (ID) Sensor cannot be calibrated to a value in the target range. Upper limit (initially 2.97 V) Lower limit (initially 2.31V) * This is the sensor on the left as viewed from the front.
Causes: - Disconnected TM(ID) Sensor connector/bad contact - Stained TM(ID) Sensor window - Failed TM(ID) Sensor - Image Transfer Belt loosened or out of place
Remedy: • Check the TM(ID) Sensor • Clean the TM(ID) Sensor Detection window • Check the Image Transfer Belt • Replace the TM(ID) Sensor
Code: SC370-02
Description: TM(ID) Sensor calibration error (Left)* The specular light output voltage (Vsg_reg) of the Left TM(ID) Sensor cannot be calibrated to a value in the target range. Upper limit (initially 2.97 V) Lower limit (initially 2.31V)
Causes: - Disconnected TM(ID) Sensor connector/bad contact - Stained TM(ID) Sensor window - Failed TM(ID) Sensor - Image Transfer Belt loosened or out of place
Remedy: • Check the TM(ID) Sensor • Clean the TM(ID) Sensor Detection window • Check the Image Transfer Belt • Replace the TM(ID) Sensor
Code: SC396-01
Description: Drum Motor: K Error Early Detection • A command to stop the rotation of the motor has been issued right after the power was turned on, but the motor is still rotating. Motor Operation Timing • When the motor rotation request or speed change request is issued, the motor is in the stopped state. Motor Stop Timing • A command to stop the rotation of the motor has been issued, but the motor is still rotating.
Causes: - Disconnected connector - Broken signal wire - Excessive motor torque
Remedy: • Check the connector connection. • Turn the power OFF and then ON. • Replace the Drum Motor: K.
