Inkjet printers express various colors by combining cyan (blue), magenta (red) and black colors.
Because the sprayed quantity of each color depends on the printed data and its exhaustion time is different, a certain color will be exhausted before other colors.
When the printer is used without refilling, the nozzle of the exhausted color will dry up (become damaged) and the cartridge cannot be reused.
When the three colors are refilled at the same time after one color is exhausted, it is difficult to find out the remained quantities of the normally printing colors, and because of this, there is a danger of their being over injected. Therefore, for stable reuse of the color cartridge, we recommend that you refill only the exhausted color, even if it is more troublesome.
