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).

Abstract: An ink quality system for an inkjet printer includes an ink reservoir including a volume of ink. A first sensor is disposed in the ink reservoir. At least a portion of the first sensor is in contact with the volume of ink. A second sensor is disposed in the ink reservoir. At least a portion of the second sensor is in contact with the volume of ink. Electronic circuitry is in electrical communication with the first sensor and the second sensor and configured to measure a quality of the ink by measuring the resistance between the first sensor and the second sensor.

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 method of operating a continuous inkjet printer (1). The printer comprise a printhead. The printhead comprises a droplet generator (16) comprising a printing nozzle (17) for ejecting an ink jet for printing, at least one electrode (22, 23) for steering the inkjet, and a gutter (18) having an ink receiving orifice (24) for receiving parts of the ink jet which are not used for printing. The method comprises performing a cleaning operation. Said cleaning operation comprises: ejecting a solvent jet from the printing nozzle towards the gutter; and causing at least a portion of the solvent jet to contact at least a part of the gutter (18) surrounding the orifice (24) for cleaning said part of the gutter surrounding the orifice.
