• Code: SC496-00
• Description: MUSIC Sensor Error MUSIC failed while power was on. Details: • TM sensor sampling error • Sensor LED adjustment abnormal • Number of patches abnormal • ITB scratched • Main scan registration abnormal • Sub scan registration abnormal • Main scan magnification abnormal • Main scan magnification error diffusion abnormal
• Causes: • ITB scratched or smudged • Sensor smudged or defective • Pattern density abnormal
• Remedy: • Cycle the machine off/on. • Replace the TM sensor. • Replace the ITB. • Process control • Cleaning

• Code: SC497-00
• Description: Temperature/Humidity Sensor Error (PCU) One of the following occurred. • The temperature sensor output was less than 0.5V or more than 2.8V for three seconds (one second x 3), indicating a problem with the temperature sensor. • The humidity sensor output was more than 2.4V for three seconds (one second x 3), indicating a problem with the humidity sensor. Details: Detection is repeated after power off/on. If either of temperature/humidity sensors works correctly, the working sensor will be used even after the SC is issued. The machine continues working with the assumption that the temperature is 23 degrees centigrade (if there is a problem with the temperature sensor) and/or the humidity is 50% (if there is a problem with the humidity sensor).
• Causes: • Connector disconnected or harness broken • Sensor defective
• Remedy: • Connector disconnected or harness broken: Revert connection. • Sensor defective: Replace the sensor.

• Code: SC501-01
• Description: 1st Tray Lift Error (A3 extended tray) 1st tray lift motor lift error was detected. If detected for the first or second time: User is instructed to set paper again. If detected for the third time: SC displayed (only the corresponding tray) The count of detections is reset when successful operation is detected and at power off/on.
• Causes: • 1st tray lift motor disconnected/harness broken/defective • 1st tray lift sensor disconnected/defective/smudged • Paper end sensor disconnected/defective/smudged • Paper overloaded • Foreign object (such as a piece of paper) is stuck between the paper tray and the tray lift motor. • Paper set incorrectly.
• Remedy: • Load paper again. • Check the harness of the tray lift sensor,/reconnect the sensor connector/clean the sensor/replace the sensor/replace the 1st tray. • Check the harness of the paper end sensor/reconnect the sensor connector/clean the sensor/replace the sensor. • Replace the 1st tray lift motor/reconnect the connector/replace the harness/replace the PFB/Replace the right tray (of the tandem tray)/replace the driven unit.
