		Go to the SP5-102-203 (AutoDetect: HumanDetectSetting). Cover the sensor with 10 sheets of plain paper, and then execute the SP. Make sure that it becomes "0". (Do not place your hand near the sensor, even over the paper, when covering the sensor) Remove the paper from the sensor and make sure that it becomes "1". If the sensor reacts normally in step 2 and 3, check if there are any other possible factors around the machine that may cause the temperature change such as a heater or a fan. (Deal with the issue as necessary) Replace the proximity sensors (human detection sensors) and proximity sensor (human detection sensor) board if an abnormal value is detected during steps 2 and 3. Turn on the main power on and perform steps 1, 2, and 3 again. If the SC is not solved, turn the main power off and replace the harness which connects the proximity sensors (human detection sensors) and the proximity sensor (human detection sensor) board. If the SC is still not solved, there is a possibility that other parts of the machine such as the connector at the controller side or the harness between proximity sensor (human detection sensor) board and IPU are broken.

  6.12 TROUBLESHOOTING FOR SC ERRORS​

  
  

  6.12.1 WHEN SC285-02 (MUSIC ERROR) IS DISPLAYED​

  
  

  Causes​

• The ID sensor cannot detect the MUSIC pattern
• Color registration error is larger than the specified value [Assumed Cause]

1. Large drifting​

   "Large drifting" is the state where the color registration error is larger than the specified value. In the "Large drifting" state, the MUSIC pattern is shifted a long distance in the main scan direction (side to side), and is moved to the position where the MUSIC Sensor (TM/ID sensor) cannot be detected, or each pattern cannot be detected due to the pattern overlapping.

2. MUSIC pattern density error​

   Pattern with the lower density

3. Defective Image transfer belt/Image transfer unit​

   • Belt scratched
   • Belt corrugation, belt skew
   • Cleaning failure
   • Background stains
   • Filming
     "Filming" is a phenomenon where surface properties change over time.
     Glossiness is one of the surface properties. In the "Filming" state, the whole or part (belt shaped) of the Image Transfer Belt surface becomes foggy. "Filming" changes reflected light, and the MUSIC Sensor (TM/ID sensor) may detect the input wrongly, which causes an error.

4. MUSIC sensor (TM/ID sensor) defective​

   • Connector/ harness disconnected
   • Sensor surface dirty
   • Sensor malfunction
   • BCU malfunction

5. Paper transfer contact/release mechanism defective​

   • Connector/ harness disconnected
   • Motor/ sensor malfunction
   • Imaging IOB malfunction

6. Laser optics positioning motor in laser unit defective​

   • Connector/ harness disconnected
   • Motor malfunction
   • Imaging IOB malfunction

Solutions​

As SC285-02 is a logging SC (SC Type C), it is not displayed at once when an error occurs. Though the equipment can be operated, check the SC history and perform a recovery operation if the SC has occurred.

Countermeasure (1): Large drifting​

An abnormal value may be contained in the SP where the MUSIC corrected result is saved.

1. Execute SP2-180-001 (Line Pos. Adj.: Clear Color Regist.).
2. Execute SP2-111-004 (Forced Line Position: Adj. Mode d).
3. Execute SP2-194-007 (MUSIC Execution Result: Execution Result).

Countermeasure (2): MUSIC pattern density Error​

Execute MUSIC and check the result.

1. Execute SP3-011-001 (Manual ProCon :Exe : Normal ProCon).
