Publication number: 20170173954Abstract: A fluid ejection device includes a body defining an interior bore, a fluid reservoir, and a fluid ejection chip. The fluid reservoir defines an interior passage that receives a fluid, the interior passage in fluid communication with the interior bore of the body. The fluid ejection chip is coupled with the body and includes one or more fluid ejection actuators. The fluid ejection chip has one or more interior fluid paths in fluid communication with the interior bore of the body so that the fluid ejection chip ejects the fluid upon activation of the one or more fluid ejection actuators. The interior passage of the fluid reservoir and the one or more interior fluid paths are substantially devoid of obstructions such that the fluid is gravity fed to the fluid ejection chip upon entry into the interior passage of the fluid reservoir.Type: ApplicationFiled: March 6, 2017Publication date: June 22, 2017Inventor: Sam Norasak

Publication number: 20170165974Abstract: A printhead assembly for an inkjet printer has a ink filter tower portion that contains filtered ink and includes multiple, substantially parallel extending elements. Settling of ink in an ink filter tower could clog the printhead nozzles and lessen the print quality. Therefore, in order to prevent the settling of the ink in the ink filter tower of the present design, a free-floating weighted slider is installed within the ink filter tower. The weighted slider has a top bridging member and downward-pointing shafts that are movable within trenches formed between the extending elements. During a reciprocating motion of the printhead assembly, the slider moves in a direction opposite to the direction of the printhead assembly and thereby agitates the ink within the tower. In addition to sliding from side to side of the printhead assembly, the slider may also be designed to pivot about an upper axis as it moves to further agitate the ink.Type: ApplicationFiled: January 13, 2017Publication date: June 15, 2017Inventors: Sam Norasak, Shane McKinney, Richard Warner

Publication number: 20170136766Abstract: Methods for ejecting fluids having a viscosity ranging from about 20 mPa-sec to about 100 mPa-sec at 22° C. from a micro-fluid ejection head. The methods include the steps of applying a heat signal to the ejection head for a first period of time to heat the ejection head to a first temperature that is about 20° C. above a steady state fluid ejection temperature for continuous or intermittent fluid ejection from the ejection head; and subsequently, applying a firing signal to ejection heaters on the ejection head during which fluid ejection from the ejection head occurs.Type: ApplicationFiled: November 13, 2015Publication date: May 18, 2017Inventors: Sam NORASAK, Stephen T.

Publication number: 20170136764Abstract: A portable large format inkjet printer for printing an image at a media print area of a stationary flat media includes an inkjet print engine having a printhead carrier system configured to dynamically scan an inkjet printhead over the media print area in each of two orthogonal directions during the printing of the image. An alignment frame is configured to fixedly mount the inkjet print engine to facilitate a manual positioning of the alignment frame and the inkjet print engine in unison. The alignment frame has an open interior window within which the inkjet printhead is moved and from which all printing occurs. At least one alignment panel is mounted to the alignment frame. Each respective alignment panel has an alignment indicia configured to facilitate accurate manual positioning of the portable large format inkjet printer at a desired printing position at the media print area.Type: ApplicationFiled: November 17, 2015Publication date: May 18, 2017Inventors: Sam Norasak, Michael A.

Patent number: 9650525Abstract: An ink composition, a printer and a method for ejecting and aqueous fluid having a viscosity above about 1 Pa-sec at 25° C. from a fluid ejection head. The ink composition, printer and method include an aqueous fluid that contains an aqueous carrier component, solid particles ranging from about 8 wt. % to about 25 wt. % based on a total weight of the aqueous fluid, and a rheology modifier. A heater pulse signal applied to ejection heaters on a fluid ejection head for a period of time is sufficient to sputter fluid from fluid ejection nozzles associated with the ejection heaters and to shear the fluid thereby reducing the viscosity of the fluid from above about 1 Pa-sec to less than about 0.1 Pa-sec. A firing signal subsequently applied to the ejection heaters on the ejection head provides steady state fluid ejection from the ejection head.Type: GrantFiled: August 9, 2016Date of Patent: May 16, 2017Assignee: FUNAI ELECTRIC CO., LTD.Inventors: Ajay K. Suthar, Sam Norasak
