Besides better ink droplets and consistency, the working life of the print head has improved dramatically.

The DX7 is much more durable than DX5 for the eco-solvent ink printing. MT-Starjet 7702L printer is equipped with two high efficient DX-7 print heads, and it is proved to have 15% print head increasing.

DX-7 print head with micro piezo print technology can show not only the excellent printing quality, but also the durability to the Eco-solvent inks. DX-7 print head has a longer and more durable working life. The improvement of printing precision makes the ink droplets smaller, and the stability is better than that of DX-5 print head.
