Replace the RADF board. YES Replace the RADF board.

• Code: E722
• Description: Jam not reaching the exit sensor (during scanning): The original which passed the read sensor does not reach the exit sensor when it is transported from the scanning section to exit section.
• Remedy: Is the read roller stained? YES Clean the roller. NO Are the exit sensor and reverse sensor working? (Perform the input check: 03-[FAX]ON/[7]/[E], /[7]/[F]) NO 1. Check if the connectors of the exit sensor and reverse sensor are disconnected. 2. Check if the connector CN4 on the RADF board is disconnected. 3. Check if the connector pins are disconnected or the harnesses are opencircuited. 4. Check if the conductor pattern on the RADF board is short- or open-circuited. 5. Replace the exit sensor and reverse sensor. 6. Replace the RADF board. YES Replace the RADF board.

• Code: E723
• Description: Jam not reaching the reverse sensor (during scanning): The original which passed the read sensor does not reach the reverse sensor when it is transported from the scanning section to reverse section.
• Remedy: Is the read roller stained? YES Clean the roller. NO Are the exit sensor and reverse sensor working? (Perform the input check: 03-[FAX]ON/[7]/[E], /[7]/[F]) NO 1. Check if the connectors of the exit sensor and reverse sensor are disconnected. 2. Check if the connector CN4 on the RADF board is disconnected. 3. Check if the connector pins are disconnected or the harnesses are opencircuited. 4. Check if the conductor pattern on the RADF board is short- or open-circuited. 5. Replace the exit sensor and reverse sensor. 6. Replace the RADF board. YES Replace the RADF board.

• Code: E724
• Description: Stop jam at the registration sensor: The trailing edge of the original does not pass the registration sensor after its leading edge has reached this sensor.
• Remedy: Is the registration roller stained? YES Clean the roller. NO Is the registration sensor working? (Perform the input check: 03-[FAX]ON/[2]/[A]) NO 1. Check if the connector of the registration sensor is disconnected. 2. Check if the connector CN3 on the RADF board is disconnected. 3. Check if the connector pins are disconnected or the harnesses are opencircuited. 4. Check if the conductor pattern on the RADF board is short- or open-circuited. 5. Replace the registration sensor. 6. Replace the RADF board. YES Replace the RADF board.

• Code: E725
• Description: Stop jam at the read sensor: The trailing edge of the original does not pass the read sensor after its leading edge has reached this sensor.
• Remedy: Is the read roller stained? YES Clean the roller. NO Is the read sensor working? (Perform the input check: 03-[FAX]ON/[7]/[G]) NO 1. Check if the connector of the read sensor is disconnected. 2. Check if the connector CN6 on the RADF board is disconnected. 3. Check if the connector pins are disconnected or the harnesses are opencircuited. 4. Check if the conductor pattern on the RADF board is short- or open-circuited. 5. Replace the read sensor. 6. Replace the RADF board. YES Replace the RADF board.

• Code: E726
• Description: Transport/exit signal reception jam: RADF receives the transport/exit reception signal from the equipment when no original is at the exposure waiting position.
• Remedy: 1. If the original is remained in the RADF, remove it. 2. If any paper is remained in the equipment, remove it. 3. Turn the power OFF and then back ON. If the jam still occurs, lead the following procedure. 4. Check the connection between the RADF board and SLG board, and the connection between the RADF board and switching power supply. - Are the connection of the connectors and joint connectors normal? - Are the connector pins disconnected or are the harnesses open-circuited? 5. Check if the 24V and 5V outputs of the switching power supply are normal. 6. Check if the conductor pattern on the RADF board is short- or open-circuited. 7. Replace the RADF board. 8. Check if the conductor pattern on the SLG board is short- or open-circuited. 9. Replace the SLG board.
