Ink cartridge features
This machine uses four ink cartridges: a black one and three color ones with a slightly lower
capacity. It features horizontal insertion in the ink refill base over plastic needles.
Each cartridge has two ports: one supplying the ink for printing and another intaking air to
replace that ink. Both ports have a disc valve preventing ink leakage. When a cartridge is
mounted over the plastic needles in the ink refill base, these valves are opened to secure flow
paths for both the ink and the air.
These ink cartridges are single-use affairs. There is no provision for refilling them. The design
reduces environment load by using only burnable materials yielding no toxic substances.
Inks
This machine uses dye-based inks for colors and pigment-based ink for black. Using the
pigment-based black ink reduces fuzziness from print character outlines, boosts resolution for
black dots, and produces clearer images on plain paper.
