    Abstract: A continuous ink jet print head (10), including: an ink droplet generator (116) configured to emit an ink droplet (158) along an undeflected droplet flight path (30); a charge electrode (118) configured to impart a charge to the ink droplet; deflector plates (120A, 120B) adjacent the undeflected droplet flight path, downstream from the charge electrode, and configured to deflect the ink droplet to a deflected droplet flight path that lies within a range of deflected flight paths bounded by at least deflected droplet flight path and a most deflected droplet flight path; a gutter (122) configured to receive an ink droplet traveling along the undeflected droplet flight path; and an ink buildup sensor (102) configured to detect an accumulation of ink (140) relative to a droplet flight path disposed within the range of deflected flight paths.

    Abstract: A continuous ink jet printer including an ink tank for holding ink, an ink nozzle in fluid communication with the ink tank for ejecting ink droplets, and a gutter for receiving, through an ink-receiving inlet thereof, ink droplets which are not used for printing. A gutter flow path starts at the ink-receiving inlet for ink that has entered the gutter through the ink-receiving inlet, and provides fluid communication to the ink tank. A return line is in fluid communication with the gutter for conveying air to enter the gutter flow path. A makeup tank is in vapor communication with the ink tank to allow air to be conveyed from the ink tank to the makeup tank. A condenser is in fluid communication with the makeup reservoir and the return line for condensing solvent.

    Abstract: An ink system of an ink jet printer includes a fluid tank. The fluid tank includes a generally conically shaped side wall, the side wall sloping inwardly from a top portion to a bottom portion. A bottom surface is disposed adjacent the bottom portion of the side wall. A first fluid conduit is disposed in the fluid tank and includes an opening adjacent to and above the bottom surface of the fluid tank. A second fluid conduit is disposed in the fluid tank and includes an opening at a location above the opening of the first fluid conduit. A pump is in fluid communication with the first fluid conduit and the second fluid conduit. An ink supply line is in fluid communication with the pump. A print head is in fluid communication with the ink supply line.

    Abstract: There is provided a charge electrode for charging ink droplets for continuous ink jet printing. The charge electrode has a generally cylindrical main body defining a generally cylindrical passage for the ink droplets, said passage extending along a travel axis that represents, in use, the position of an ink jet in ingress to the electrode and a direction of travel of the ink droplets once these have detached from the ink jet. The charge electrode comprises two distinct axially disposed regions: a first region for charging the droplets as required; and, a second region for screening the charged droplets from any electric fields which could undesirably affect the trajectory of the ink jet and/or the droplets. The second region may fully surround at least a portion of the travel axis. The invention therefore provides improved screening for the ink jet and/or the droplets. This may in turn enable better control of the charge applied to the charged droplets, and/or of their travel trajectory.

    Abstract: A filter module (38) for a continuous inkjet printer (10) comprising a filter housing (40) and a filter medium (42) fixed within the housing (40). The filter housing (40) further includes an inlet portal (44) through which ink flows into the housing under pressure and a first self-sealing valve assembly (54) disposed within the inlet portal. In addition, housing includes an outlet portal (46) through which ink flows out of the housing (40) under pressure and a second self-sealing valve assembly (56) disposed within the outlet portal (46). The first and second valve assemblies (54, 56) open when mechanically connected to an ink flow path (34) from an ink tank (18) to a print head (14), and the first and second valve assemblies (54, 56) seal closed when mechanically disconnected from the ink flow path (34).
