• Description: Edge Press Plate HP Sensor (S90) Error PB (D391) During edge press plate operation during trimming: The edge press plate HP sensor did not go OFF within the prescribed time because it failed to pull away from the HP sensor. The edge press plate HP sensor did not ON within the prescribed time because it failed to arrive at the HP sensor. The edge press motor (M36) stopped when the press HP sensor (S90) switched ON, but after the motor stopped the HP sensor went OFF.
• Causes: • Edge press motor (M36) connections loose, broken, defective • Motor defective • Edge press plate HP sensor (S90) harness loose, broken, defective • Sensor defective
• Remedy:

• Code: 795-24
