• Code: 734
• Description: Upper Tray Junction Gate Motor: 3K Finisher B830 The upper tray junction gate HP sensor did not detect the gate at the home position within 200 ms after two attempts. -or- The HP sensor twice detected the gate at the home position for more than 200 ms after it was supposed to open. The 1st failure causes a jam error, and the 2nd failure causes this SC code.
• Causes: • Junction gate did not arrive at the home position within the specified time. • Junction gate did not leave the home position within the specified time.
• Remedy: 1. Check or clear obstacles around the motor drive mechanism. 2. Check the harness connection. 3. Replace the upper tray junction gate HP sensor. 4. Replace the upper tray junction gate motor. 5. Replace the finisher main board.

• Code: 735
• Description: Staple Junction Gate Motor Error: 3K Finisher B830 The staple tray junction gate HP sensor did not detect the gate at the home position within 200 ms after two attempts. -or- The HP sensor twice detected the gate at the home position for more than 200 ms after it was supposed to open. The 1st failure causes a jam error, and the 2nd failure causes this SC code.
• Causes: • Junction gate did not arrive at the home position within the specified time • Junction gate did not leave the home position within the specified time
• Remedy: 1. Check or clear obstacles around the motor drive. 2. Check the harness connection. 3. Replace the staple tray junction gate HP sensor. 4. Replace the staple junction gate motor. 5. Replace the finisher main board.

• Code: 736
• Description: Pre-Stack Junction Gate Motor Error: 3K Finisher B830 The pre-stack junction gate HP sensor did not detect the gate at the home position for within 200 ms after two attempts. -or- The HP sensor twice detected the gate at the home position for more than 200 ms after it was supposed to open. The 1st failure causes a jam error, and the 2nd failure causes this SC code.
• Causes: • Junction gate did not arrive at the home position within the specified time • Junction gate did not leave the home position within the specified time
• Remedy: 1. Check or clear obstacles around the motor drive mechanism. 2. Check the harness connection. 3. Replace the pre-stack junction gate HP sensor. 4. Replace the pre-stack junction gate motor. 5. Replace the finisher main board.
