e) 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.
f) Ink supply valves
Located halfway between each subtank and the ink tube, the ink supply valve prevents ink leaks that may occur when the ink tube on the ink tank is released during
replacement of the ink tank.
The ink supply valve is opened and closed by a valve open/close mechanism.
The ink tank unit consists of a tank base into which five-color ink tanks are assembled, and ink tubes for six colors (two occupied by MBK). Each color-specific
ink supply valve is linked to the action of a valve cam so the ink supply valves will open and close simultaneously for all the colors.
