• Code: SC392
• Description: TD sensor initial setting error Initialization of the new PCU unit failed (the drum and development roller did not start rotating)
• Causes: • ID sensor defective • TD sensor defective • Developing roller does not rotate • OPC drum does not rotate
• Remedy: • Replace the the ID sensor. • Replace the TD sensor.

• Code: SC401
• Description: Transfer positive electrode current error A transfer roller current leak signal is detected. (The current feedback signal for the transfer roller was not detected within the correct time.)
• Causes: • High voltage supply board set incorrectly or defective • Transfer roller set incorrectly or damaged • Transfer unit set incorrectly
• Remedy: • Cycle the main power off/on • Check the high voltage supply board is set correctly. • Check the harness of the high voltage supply board. • Replace the high voltage supply board. • Check the transfer roller is set correctly. • Replace the transfer roller. • Check the transfer unit is set correctly.

• Code: SC402
• Description: Transfer negative electrode current error A transfer roller current leak signal is detected. The current feedback signal for the transfer roller is not detected within the correct time.
• Causes: • Transfer roller set incorrectly or damaged • High voltage supply board set incorrectly or defective
• Remedy: • Cycle the main power off/on • Check the high voltage supply board is set correctly. • Check the harness of the high voltage supply board. • Replace the high voltage supply board. • Check the transfer roller is set correctly. • Replace the transfer roller.

• Code: SC411
• Description: Separation bias leak error A separation bias leak signal was detected.
• Causes: • High voltage supply board set incorrectly or detective • Discharge plate set incorrectly or detective
• Remedy: • Cycle the main power off/on • Check the harness of the high voltage supply board. • Replace the high voltage supply board. • Replace the harness. • Replace the discharge plate.

• Code: SC490
• Description: Toner supply motor leak errorr More than 1 ampere supplied to the toner supply motor for longer than 200 ms.
• Causes: • Toner supply motor defective
• Remedy: • Replace the toner transport motor.

• Code: SC500
• Description: Main motor lock. The machine detected motor lock (motor is not operating correctly)
• Causes: • An obstruction has blocked operation of the main motor • Main motor harness loose or broken • Main motor or main motor driver board defective • Overload on the main motor
• Remedy: • Replace the harness of the main motor. • Replace the motor. • Replace the main motor driver board. • Check for the blockages in the main motor mechanism.

• Code: SC501
• Description: Paper Tray1 error • When the tray lift motor rotates counterclockwise, (if the upper limit is not detected within 10 seconds), the machine asks the user to reset the tray. • When the tray lift motor rotates clockwise, (if the upper limit is not detected within 1.5 seconds), the machine asks the user to reset the tray. If one of these conditions occurs three consecutive times, the SC is generated.
• Causes: • Disconnected or defective paper lift sensor • Disconnected or defective tray lift motor • Defective bottom plate lift mechanism • Too much paper in the tray • Defective BCU
• Remedy: • Check if the paper is not loaded too much. • Check if the bottom plate smoothly moves up and down manually. • Check and/or replace the tray lift motor/ paper lift sensor. • Replace the BCU.

• Code: SC502
• Description: Paper Tray2 error • When the tray lift motor rotates counterclockwise, (if the upper limit is not detected within 10 seconds), the machine asks the user to reset the tray. • When the tray lift motor rotates clockwise, (if the upper limit is not detected within 1.5 seconds), the machine asks the user to reset the tray. If one of these conditions occurs three consecutive times, the SC is generated.
• Causes: • Disconnected or defective paper lift sensor • Disconnected or defective tray lift motor • Defective bottom plate lift mechanism • Too much paper in the tray • Defective BCU
• Remedy: • Check if the paper is not loaded too much. • Check if the bottom plate smoothly moves up and down manually. • Check and/or replace the tray lift motor/ paper lift sensor. • Replace the BCU.
