SC514-00	D	Inverter Junction Gate Motor Error
		Inverter junction gate home position sensor did not turn on or off within 150 msec 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.
		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.
		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.

SC515-01	B	Duplex Transport Shift Motor 1 Error
		When an error occurs during duplex transport 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 on the third consecutive occurrence.
		Duplex transport shift motor 1 connector disconnected or defective Motor driver defective Duplex transport home position sensor 1 connector disconnected or defective Duplex transport shift motor 1 does not move because of overload which may be due to foreign objects, etc. Duplex transport home position sensor 1 deformed, damaged or connected incorrectly
		Turn the machine OFF\ON to see the SC. After turning the machine OFF\ON, feed 10 sheets of the duplex paper three times. Check whether SC515-01 occurs (JAM097 occurs up to two times). Check the driven parts. Rotate the duplex transport shift motor 1 by hand and check the load. If the load is too high due to foreign objects or jams, remove the foreign object or replace the part. Check and reconnect the connector and harness. Duplex transport shift motor 1 connector DUB board CN296 and CN303 Duplex transport home position sensor 1 connector Clean the duplex transport home position sensor. Execute Input check and Output check. Rotate the duplex transport shift motor 1 by hand and check whether the value of SP5-803-164 (Input check roller home detection sensor 1) changes to 0 or 1. If the value does not change, replace the duplex transport home position sensor. Reinstall the drawer, and execute SP5-806-195 (Output check duplex transport shift motor 1: homing) to check if the duplex transport shift motor 1 moves. If the duplex transport motor 1 does not move, replace the following motor and harness. Duplex transport shift motor 1 Duplex transport shift motor 1 connector Replace the DUB and PFB.

SC515-02	B	Duplex Transport Shift Motor 2 Error
		When an error occurs during duplex transport 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 on the third consecutive occurrence.
		Duplex transport shift motor 2 connector disconnected or defective Motor driver defective Duplex transport home position sensor 2 connector disconnected or defective Duplex transport shift motor 2 does not move because of overload which may be due to foreign objects, etc. Duplex transport home position sensor 2 deformed, damaged or connected incorrectly
		Turn the machine OFF\ON to see the SC. After turning the machine OFF/ON, feed 10 sheets of the duplex paper three times. Check whether SC515-02 occurs (JAM097 occurs up to two times). Check the driven parts. Rotate the duplex transport shift motor 2 by hand and check the load. If the load is too high due to foreign objects or jams, remove the foreign object or replace the part. Check and reconnect the connector and harness. Duplex transport shift motor 2 connector DUB board CN296 and CN303 Duplex transport home position sensor 2 connector Clean the duplex transport home position sensor. Execute Input check and Output check. Rotate the duplex transport shift motor 2 by hand and check whether the value of SP5-803-165 (Input check roller home detection sensor 2) changes to 0 or 1. If the value does not change, replace the duplex transport home position sensor. Reinstall the drawer, and execute SP5-806-200 (Output check duplex transport shift motor 2: homing) to check if the duplex transport shift motor 2 moves. If the duplex transport shift motor 2 does not move, replace the following motor and harness. Duplex transport shift motor 2 Duplex transport shift motor 2 connector Replace the DUB and PFB.

SC516-01	B	Edge Detection Sensor Shift Motor Home Position Error
		When an error occurs during edge detection 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.
		Edge detection sensor shift motor connector disconnected or defective Motor driver defective Sensor shift home position switch connector disconnected or defective Edge detection sensor shift motor does not move because of overload which may be due to foreign objects, etc. Sensor shift home position switch deformed, damaged or connected incorrectly
		Turn the machine OFF\ON to see the SC. After turning the machine OFF/ON, feed 10 sheets of the duplex paper to see the SC. Check the driven parts. Open the lower guide plate, and check the load by moving the edge detection sensor bracket. If the load is too high due to foreign objects or jams, remove the foreign object or replace the part. Check and reconnect the connector and harness. Edge detection sensor shift motor connector DUB board CN296 and CN303 Sensor shift home position switch connector Clean the sensor shift home position switch. Execute Input check and Output check. Open the guide plate and move the edge detection sensor bracket by hand, and check whether the value of SP5-803-166 (Input check sensor shift home position sensor) changes to 0 or 1. If the value does not change, replace the sensor shift home position switch. Reinstall the drawer, and execute SP5-806-204 (sensor shift motor: low speed) to check if the edge detection sensor shift motor moves. If the edge detection sensor shift motor does not move, replace the following motor and harness. Edge detection sensor shift motor Edge detection sensor shift motor connector Replace the DUB and PFB.
