f) Subtank
The subtank installed under each ink tank complements the work of the ink tank, agitating the ink in the tank.
If the ink tank runs out of the ink while printing, the ink stored in the subtank is available, allowing the ink tank to be replaced without having to stop printing.
g) 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 (Left/Right) consist of tank bases each of which contains ink tanks for three colors and the ink tubes for three colors.
Ink supply valves for all colors are opened and closed at the same time.
h) Subtank air passage valve
The subtank air passage valves keep the internal pressure of the subtank adequately.
The subtank air passage valve is opened and closed by the valve open/close mechanism which is driven by the valve motor.
