• Code: C2152
• Description: Transfer belt pressure welding alienation
  • At the completion of transfer belt pressure/ retraction operations, the pressure welding alienation sensor/K or the pressure welding alienation sensor/color is not in the status corresponding to each of the transfer belt pressure/retraction operations. See the table below. • Even after a predetermined period of time has elapsed since the transfer belt starts pressure/retraction operation, the pressure welding alienation sensor/K or the pressure welding alienation sensor/color is not in the status corresponding to each of the transfer belt pressure/retraction operations. See the table below. Operation Position Sensor status (K: Color) • Color and K retraction - K pressure • Color and K pressure - K pressure ON (not blocked) :OFF (blocked) pressure • Color and K retraction - Color and K pressure • K pressure - Color and K pressure Color and K pressure ON (not blocked):ON (not blocked) • K pressure - Color and K retraction • Color and K pressure -Color and K Color and K retraction OFF (blocked): OFF (blocked)
