Code: SC509-04
Description: Bypass tray Paper Set Error Both the upper limit sensor and the lower limit sensor were on when the machine attempted to adjust the bottom plate position before starting paper feed (at Job-In). If detected for the first to fourth time: User is instructed to set paper again. If detected for the fifth time: SC displayed (only the corresponding tray) The count of detections is reset when successful operation is detected and at power off/on.
Causes: • Bypass tray upper limit sensor defective/disconnected/harness broken • Circuit board (PFB) error • Paper overloaded
Remedy: • Bypass tray upper limit sensor and lower limit sensor check/ cleaning/replacement/harness reconnection/harness replacement • Check or replace the circuit board (PFB). • Check the paper capacity.

Code: SC511-01
Description: Paper Thickness Sensor Error During initial calibration of the paper thickness sensor, the number of times the sensor failed to output an appropriate value reached 3. The counter is reset at the start of initial calibration.Bypass Tray Paper Thickness Sensor Error During initial calibration of the bypass tray paper thickness sensor, the number of times the sensor failed to output an appropriate value reached 3. The counter is reset at the start of initial calibration.
Causes: • Paper thickness sensor harness broken/connecter disconnected • Paper thickness sensor dirty with paper dust, etc. • Foreign object on the section of the roller which is used for paper thickness detection.
Remedy: • Check the harness and connector of the sensor. • Clean or replace the sensor. • Clean or replace the section of the roller which is used for paper thickness detection.

Code: SC511-02
Description: Bypass Tray Paper Thickness Sensor Error During initial calibration of the bypass tray paper thickness sensor, the number of times the sensor failed to output an appropriate value reached 3. The counter is reset at the start of initial calibration.
Causes: • Paper thickness sensor harness broken/connecter disconnected • Paper thickness sensor dirty with paper dust, etc. • Foreign object on the section of the roller which is used for paper thickness detection.
Remedy: • Check the harness and connector of the sensor. • Clean or replace the sensor. • Clean or replace the section of the roller which is used for paper thickness detection.

Code: SC514-00
Description: Inverter Junction Gate Motor Error Inverter junction gate home position sensor did not turn on or off within 150msec from the start of home position detection operation (motor drive start). Details: If detected for the first or second time: • During paper transport, this is not handled as a jam/SC; paper is fed normally and the error counter increases. • Otherwise (during initialization), a jam alert is displayed to instruct the user to remove jammed paper, and the error counter increases. If detected for the third time: • Displays the SC No. on the operation panel.
Causes: • Inverter junction gate motor defective/connector disconnected/ harness broken • Inverter junction gate home position sensor defective/connector disconnected/harness broken • Circuit board (PFB, DUB) defective • Junction gate/junction gate drive unit does not move e.g. because physical obstacle (piece of paper, etc.) is blocking operation.
Remedy: • Inverter junction gate motor and inverter junction gate home position sensor check/cleaning/replacement/harness reconnection/ harness replacement • Check or replace the circuit board (PFB, DUB). • Check and/or replace the inverter junction gate and inverter junction gate drive unit.

Code: SC515-01
Description: Roller Shift Motor 1 Error When an error occurs during roller shift motor 1 home position detection, the machine handles it as a jam (JAM097) and stops operation, and displays the SC No. on the control panel.
Causes: • Roller shift motor 1 connector disconnected or defective • Motor driver defective • Roller home position sensor 1 connector disconnected or defective • Roller shift motor 1 does not move because of overload which may be due to foreign objects, etc. • Roller home position sensor 1 deformed, damaged or connected incorrectly
Remedy: • Clean the roller home position sensor 1 and check its harness. • Reconnect the connectors of roller shift motor 1 and roller home position sensor 1. • Check and, if necessary, replace: roller shift motor 1, roller home position sensor 1, harness, circuit board (PFB, DUB), unit, driven unit.

Code: SC515-02
Description: Roller Shift Motor 2 Error When an error occurs during roller shift motor 2 home position detection, the machine handles it as a jam (JAM097) and stops operation, and displays the SC No. on the control panel.
Causes: • Roller shift motor 2 connector disconnected or defective • Motor driver defective • Roller home position sensor 2 connector disconnected or defective • Roller shift motor 2 does not move because of overload which may be due to foreign objects, etc. • Roller home position sensor 2 deformed, damaged or connected incorrectly
Remedy: • Clean the roller home position sensor 2 and check its harness. • Reconnect the connectors of roller shift motor 2 and roller home position sensor 2. • Check and, if necessary, replace: roller shift motor 2, roller home position sensor 2, harness, circuit board (PFB, DUB), unit, driven unit.

Code: SC516-01
Description: Sensor Shift Motor Home Position Error When an error occurs during sensor shift motor home position detection, the machine handles it as a jam (JAM097) and stops operation, and displays the SC No. on the control panel.
Causes: • Sensor shift motor connector disconnected or defective • Motor driver defective • Sensor shift home position sensor connector disconnected or defective • Sensor shift motor does not move because of overload which may be due to foreign objects, etc. • Sensor shift home position sensor deformed, damaged or connected incorrectly
Remedy: • Clean the sensor shift home position sensor and check its harness. • Reconnect the connectors of sensor shift motor and sensor shift home position sensor. • Check and, if necessary, replace: sensor shift motor, sensor shift home position sensor, harness, circuit board (PFB, DUB), unit, driven unit.

Code: SC516-02
Description: Sensor Shift Motor Edge Detection Error When an error occurs during sensor shift motor edge detection, the machine handles it as a jam (JAM097) the first two times and displays the SC No. on the control panel the third time.
Causes: • Sensor shift motor connector disconnected or defective • Motor driver defective • Edge detection sensor connector disconnected or defective • Sensor shift motor does not move because of overload which may be due to foreign objects, etc. • Sensor shift home position sensor deformed, damaged or connected incorrectly • Wrong paper size
Remedy: • Load paper again. • Clean the edge detection sensor and check its harness. • Reconnect the connectors of sensor shift motor and edge detection sensor. • Check and, if necessary, replace: sensor shift motor, edge detection sensor, harness, circuit board (PFB, DUB), unit, driven unit.
