f) Ink supply valve
The ink supply valve is located between the ink tank and ink tube to prevent ink leakage from occurring when the ink tube on the ink tank side is opened during
replacement of the ink tank.
The ink supply valve is opened and closed by the valve open/close mechanism which is driven by the valve motor.
The ink tank unit consists of two tank bases each of which contains ink tanks for three colors and the ink tubes for six colors.
The ink supply valve for each color is driven by the valve cam though a link. Ink supply valves for all colors are opened and closed at the same time.
