    Abstract: In an ink jet head using a thermal energy for ejecting ink, this invention aims to reliably and uniformly remove kogations deposited on a heat application portion in contact with the ink. To realize this objective, the upper protective layer is arranged in an area including the heat application portion so that it can be electrically connected to serve as an electrode which causes an electrochemical reaction with the ink. The upper protective layer is formed of a material containing a metal which is dissolved by the electrochemical reaction and which does not form, on heating, an oxide film which hinders the dissolution. With this arrangement, a reliable electrochemical reaction can be produced to dissolve a surface layer of the upper protective layer, thereby removing kogations on the heat application portion reliably and uniformly.

  • Publication number: 20130155130
    Abstract: A particle removal device for an ink jet printer is discussed. The particle removal device includes a first separator comprising an arrangement of obstacles including at least two rows of obstacles that extend laterally with respect to a flow path of ink in the first separator. The rows of obstacles are offset from one another by a row offset fraction. The arrangement of obstacles is configured to preferentially route larger particles having diameters greater than a critical diameter through the arrangement and along a first trajectory vector that is angled with respect to the direction of the flow path of the ink. The angle of the first trajectory vector with respect to the ink flow path is a function of the row offset fraction. Smaller particles having diameters less than the critical diameter travel through the arrangement along a second trajectory vector that is not substantially angled with respect to the flow path of the ink.

    Abstract: Methods for operating a printing system are provided. In one method, an inkjet printhead that is positioned by a support structure is caused to emit droplets of an ink including vaporizable carrier fluid toward a target area to emit droplets according to image data and a shield is used to separate the support structure from the target area to form a first region between the support structure and the shield and a second region between the shield and the target area with the shield providing an opening between the first region and the second region to allow the inkjet printhead to jet droplets to the target area. The shield is heated to a temperature that is at least equal to a condensation temperature of the vaporized carrier fluid in the second region.
