Abstract (en)
[origin: EP1995070A2] The system has a high capacity tank (1) from which ink is propelled to a sealed tank (3) through a pump (2). A depression is created in the sealed tank with respect to an ink-jet head (5), such that pressure of the ink in the head is lower than exterior pressure. A pressurized air connection (7) is connected to the sealed tank. An impulsion pump generates recirculation between the head and the sealed tank.
