Patent number: 9174409Abstract: A media substrate for imaging includes a front and back surface defining a thickness. The front receives imaging fluid and absorbs it. The back has scoring lines extending into the thickness that limit curling of the media substrate as the absorbed fluid dries on the front. Patterns and locations of scoring lines as well as their depth into the thickness are noted. Imaging and scoring stations in an imaging device are still other embodiments as are cutting features for scoring.Type: GrantFiled: April 27, 2012Date of Patent: November 3, 2015Assignee: Funai Electric Co., Ltd.Inventors: Sam Norasak, Colin Geoffrey Maher

Publication number: 20100033530Abstract: A priming system for priming a print head of a printing device includes an elongated hollow member, a piston mechanism, a piston driving mechanism, and a suction cup. The piston mechanism disposed in the elongated hollow member is capable of reciprocally moving in a first direction and in a second direction opposite to the first direction within the elongated hollow member. The piston driving mechanism is operatively connected to the piston mechanism at an end portion of the elongated hollow member. The piston driving mechanism is capable of reciprocally moving the piston mechanism in the first direction and in the second direction. The suction cup is disposed above the print head and operatively coupled to the elongated hollow member. The suction cup is capable of extracting ink from a plurality of nozzles of the print head, when the piston mechanism moves in the first direction.Type: ApplicationFiled: August 6, 2008Publication date: February 11, 2010Inventors: Justin Paul Bryant, Colin Geoffrey Maher, Sam Norasak, Kent Lee Ubellacker

Patent number: 7244014Abstract: An improved ink jet printhead for an ink jet printer and method therefor. The printhead includes a semiconductor substrate containing ink ejection devices. A thick film layer is attached to the substrate. A nozzle plate is attached to the thick film layer. The nozzle plate contains a plurality of ink ejection nozzles corresponding to the ink ejection devices. The printhead contains flow features having a height dimension and a width dimension formed therein for flow of ink to the plurality of ink ejection devices for ejection through the nozzles. At least a portion of the flow feature dimensions for at least one of the nozzles is formed in both the thick film layer and laser ablated in the nozzle plate, wherein the thick film layer contains at least 12% of the flow feature dimensions.Type: GrantFiled: October 28, 2003Date of Patent: July 17, 2007Assignee: Lexmark International, Inc.Inventors: Richard Louis Goin, Colin Geoffrey Maher, James Harold Powers

Patent number: 7036904Abstract: A method that provides printhead swath height measurement and compensation includes the steps of establishing a nominal printhead swath height to be associated with printheads of a particular type; printing a swath using a first printhead of the particular type; measuring a printhead swath height of the first printhead; determining a difference between the measured printhead swath height of the first printhead and the nominal printhead swath height; generating a printhead swath height correction value based on the difference; and storing the printhead swath height correction value in a printhead memory associated with the first printhead.Type: GrantFiled: October 30, 2003Date of Patent: May 2, 2006Assignee: Lexmark International, Inc.Inventors: David Golman King, Colin Geoffrey Maher, Stephen Todd Olson

Patent number: 6623103Abstract: The invention provides a method for forming ink jet nozzle structures in an ablatable material. More particularly, the invention provides uniform nozzle structure by ablating an ablatable material with a laser beam while setting a field lens unit to various locations relative to a projection lens. The resulting ink jet nozzle structures have substantially orthogonal ink delivery trajectory paths relative to a plane defined by the length and width of the ablatable material regardless of the nozzles hole position relative to the edges of the ablatable material.Type: GrantFiled: April 10, 2001Date of Patent: September 23, 2003Assignee: Lexmark International, Inc.Inventors: Colin Geoffrey Maher, James Michael Mrvos, James Harold Powers, Kent Lee Ubellacker

Patent number: 6409308Abstract: A method of forming one or more nozzles in a substrate used, for example, as a nozzle plate in an inkjet printhead of a thermal inkjet printer, using laser ablation, An opaque mask is interposed between a source of a laser beam and the substrate and includes one or more transparent, ring-shaped orifices therethrough arranged in a closely-spaced matrix. The beam is emitted from the laser source towards the mask such that the opaque portions of the mask block the beam from passing through the mask except for through the ring-shaped orifices. The beam is thereby separated into one or more ring-shaped beam portions, each of which penetrates the substrate at approximately the same and substantially constant intensity to ablate one or more ring-shaped openings in the substrate arranged on the substrate as a closely-spaced matrix. Ring-spaced openings each defines a center plug portion, which is removed from the substrate, for example, by vacuum or adhesive.Type: GrantFiled: November 19, 1999Date of Patent: June 25, 2002Assignee: Lexmark International, Inc.Inventors: Colin Geoffrey Maher, Kent Lee Ubellacker

Patent number: 6267472Abstract: A heater chip module is provided comprising a carrier adapted to be secured directly to an ink-filled container, at least one heater chip having a base coupled to the carrier, and at least one nozzle plate coupled to the heater chip. The carrier includes inner side walls and a support section which together define an inner cavity. An edge feed heater chip is coupled to the carrier support section. The heater chip includes side walls. The support section includes first and second passages which define first and second paths for ink to travel from the container to the inner cavity. The inner cavity and the heater chip are sized such that a first side wall of the heater chip is spaced from a first inner side wall of the carrier and a second side wall of the heater chip is spaced from a second inner side wall of the carrier. A nozzle plate is coupled to the heater chip and the carrier. The nozzle plate has a width such that the nozzle plate extends over an outer surface of the carrier.Type: GrantFiled: June 19, 1998Date of Patent: July 31, 2001Assignee: Lexmark International, Inc.Inventors: Colin Geoffrey Maher, Ashok Murthy, Darrin Wayne Oliver, Robert Allen Samples, Jeanne Marie Saldanha Singh, Carl Edmond Sullivan
