How do I lock the ink valve before moving the printer?
To prevent ink leakage, turn the ink valve completely to the right (horizontal position) to lock it before moving or tilting the printer. After moving the printer and before printing again, turn the valve completely to the left (vertical position) to unlock it and allow the printer to function properly. (Page 56)
