Publication number: 20130021409Abstract: In an inkjet printer having a small print head assembly and a large print head assembly, a wiper includes a first wiper section having a width approximately equal to a width of an orifice area of the small print head assembly, a decoupler adjacent to the first wiper section, a second wiper section adjacent to the decoupler, where the first and the second wiper sections and the decoupler combined have a width approximately equal to a width of an orifice area of the large print head assembly, and a squared tip at an extremity of the single, segmented wiper to impede wicking action. A tab holds the wiper oriented so as to wipe the print head assemblies in a direction of a printing operation.Type: ApplicationFiled: April 30, 2010Publication date: January 24, 2013Applicant: Hewlett-Packard Development Company, L.P.Inventors: Jafar N. Jefferson, Teressa L. Roth, Jennifer Peterson

Publication number: 20130021408Abstract: A method of minimizing ink consumption during printhead priming in an inkjet printer. The printhead has a nozzle face defining an array of nozzles for ejecting ink on to a media substrate. The method includes the steps of: providing a porous pad having a contact face dimensioned so that it can encompass all the nozzles in the array; moving the porous pad such that the contact face engages the nozzle face to cover the array of nozzles; forcing ink into the printhead under pressure until ink flows out the nozzles in the array and into the porous pad engaged with the nozzle face; and withdrawing the porous pad such that the contact face disengages the nozzle face.Type: ApplicationFiled: September 26, 2012Publication date: January 24, 2013Applicant: ZAMTEC LIMITEDInventors: John Douglas Peter Morgan, Patrick John McAuliffe, Kia Silverbrook

Publication number: 20130016158Abstract: A liquid jetting apparatus includes: a liquid jetting head configured to have a liquid jetting surface on which a plurality of nozzles, from which liquid is jetted, are open; a wiper configured to move, relative to and along the liquid jetting surface, while being brought in contact with the liquid jetting surface and to wipe the liquid adhered on the liquid jetting surface; a wiper movement mechanism configured to move the wiper in a direction orthogonal to the liquid jetting surface and to make the wiper approach to or separate from the liquid jetting surface. The wiper moving mechanism includes: a cam configured to have a cam surface; an axis configured to extend along the liquid jetting surface; and an arm member configured to make the wiper approach to the liquid jetting surface by pushing and moving the wiper in accordance with movement of the cam.Type: ApplicationFiled: July 10, 2012Publication date: January 17, 2013Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventor: Ayumu IKEDA

Patent number: 8348364Abstract: A fluid supply device, a printing device, and a method of cleaning a printing device are disclosed. A fluid supply device includes a main tank, a fluid chamber, a fluid-discharging head, a movable carriage, an expansion mechanism that expands the fluid chamber to draw fluid from the main tank, a suction mechanism, a remaining fluid detection unit, a comparison unit that compares the remaining fluid volume in the main tank with a specified value, and a setting unit that sets a cleaning mode. The expansion mechanism is actuated via a movement of the movable carriage. The setting unit sets a first cleaning mode in which a first amount of fluid is vacuumed from the nozzle or a second cleaning mode in which a second amount of fluid is vacuumed from the nozzle that is less than the first amount. The cleaning mode is selected in response to the amount of fluid remaining in the main tank.Type: GrantFiled: November 3, 2009Date of Patent: January 8, 2013Assignee: Seiko Epson CorporationInventor: Susumu Taga

Patent number: 8348382Abstract: In a cap mode where a cap member covers a nozzle surface, a controller controls a second movement mechanism so that the cap member is disposed opposite to the nozzle surface. In an ejection recovery mode where ink is ejected from a plurality of nozzles and the ink adhered to the nozzle surface is wiped off by a wiping member, the controller controls a first movement mechanism and the second movement mechanism so that the nozzle surface, a wiping tray and the cap member are arranged downward in this order.Type: GrantFiled: November 22, 2010Date of Patent: January 8, 2013Assignee: Kyocera Mita CorporationInventors: Sou Takahashi, Kikunosuke Tsuji

Publication number: 20130002756Abstract: A wiping system is disclosed. The wiping system has a wiper blade and a web wipe. The wiper blade forms an angle with the surface to be cleaned. The wiper blade has a tip formed in the front end of the wiper blade. The wiper blade moves in a wiping direction with the front end leading the rest of the blade when the wiper blade is moving in the wiping direction. The web wipe is placed between the tip and the surface to be cleaned, with the web wipe contacting both the tip and the surface to be cleaned.Type: ApplicationFiled: June 28, 2011Publication date: January 3, 2013Inventor: Adrian Kriz

Publication number: 20130002755Abstract: The invention prevents and suppresses wasteful expenditure of ink which occurs when recovering nozzles. In greater detail, a plurality of head units arranged in a direction which intersects a transportation direction of a printing medium is provided, a plurality of cleaning units is disposed to face the plurality of head units, and at least one of the plurality of cleaning units is selected and moved so as to be in close contact with the corresponding cleaning unit. By such a method, only the cleaning head unit which faces the head unit of which nozzles need to be recovered is selected and is brought into contact with the head unit, and liquid is sucked in from the nozzles of the head unit.Type: ApplicationFiled: September 10, 2012Publication date: January 3, 2013Applicant: Seiko Epson ComporationInventors: Kaneo YODA, Hiroshi MIYAZAWA
