Abstract (en)

[origin: US4862192A] The ink jet matrix printer, with an ink system, includes a transport device for transferring thick ink from a first supply container and, independently thereof, solvent from a second supply container, into an ink chamber. Ink from this ink chamber is supplied under pressure to a write head. Ink is returned into the ink chamber via a collection channel, located across from the write head and intended for ink droplets which have not been diverted for writing purposes. The transport device uses pressurized air to transport the ink between an ink container, connected to the write head, a mixer container, connected to the tawo supply containers, and a collection container, connected to the collection channel. The mixer container can alternatively be connected to a suction line or a pressure line.
