• Remedy: 1. Check or clear obstacles around the motor drive mechanism. 2. Check the harness connection. 3. Replace the feed motor.

• Code: 781
• Description: Z-Fold Lower Stopper Motor Error The lower stopper failed to leave the home position with the specified number of motor pulses. • The 1st detection failure causes a jam error, and the 2nd failure causes this SC code.
• Causes: • Lower stopper motor disconnected, defective • Lower stopper motor overloaded due to obstruction • Lower stopper HP sensor disconnected, defective
• Remedy: 1. Check or clear obstacles around the motor drive mechanism. 2. Check the harness connection. 3. Replace the lower stopper motor.

• Code: 782
• Description: Z-fold Upper Stopper Motor The upper stopper failed to leave the home position with the specified number of motor pulses. The 1st detection failure causes a jam error, and the 2nd failure causes this SC code.
• Causes: • Upper stopper motor disconnected, defective • Upper stopper motor overloaded due to obstruction • Upper stopper HP sensor disconnected, defective
• Remedy: 1. Check or clear obstacles around the motor drive mechanism. 2. Check the harness connection. 3. Replace the upper stopper motor.

• Code: 784
