Publication number: 20090085967Abstract: A capping fixture is adapted to be coupled to a droplet discharge device including a droplet discharge head aligned on a unit plate of a carriage. The capping fixture includes a base panel, a head cap portion and an elastic member. The head cap portion is disposed on the base panel at a position corresponding to the droplet discharge head to hermetically seal the droplet discharge head when the capping fixture is coupled to the carriage of the droplet discharge device. The elastic member elastically couples the head cap portion with the base panel so that the head cap portion is movable within a prescribed distance in a direction substantially perpendicular to the base panel.Type: ApplicationFiled: September 19, 2008Publication date: April 2, 2009Applicant: Seiko Epson CorporationInventors: Eijiro FUJIMORI, Takayuki IMAI, Toru SHINOHARA

Publication number: 20090085968Abstract: A mobile device is disclosed. The mobile device includes an inkjet printhead, a print media feed path for directing print media past the printhead in a feed direction during printing, and a capping mechanism including a capper moveable between a capping position in which the capper is urged into a capping relationship with the printhead, and an uncapped position in which the capper is displaced away from the printhead thereby exposing the printhead to print media in the print media feed path. The capper is moved between the capped and uncapped position by engagement with an edge of the print media as the print media moves through the feed path.Type: ApplicationFiled: November 23, 2008Publication date: April 2, 2009Inventors: Kia Silverbrook, Tobin Allen King, Gregory Michael Tow

Publication number: 20090085966Abstract: A channel member formed with a liquid storing chamber and a communication channel is configured to be tilted together with a droplet ejecting head. A cap member is configured to be movable between: a standby position spaced away from a droplet ejecting surface; and a capping position at which the cap member is in close contact with the droplet ejecting surface and covers droplet ejecting openings. A cap drive section drives the cap member to move between the standby position and the capping position. When the cap drive section drives the cap member to move to the capping position, the cap member presses the droplet ejecting head, and the channel member is tilted together with the droplet ejecting head in such a manner that a connection section between the liquid storing chamber and the communication channel is located at a position higher than the liquid storing chamber.Type: ApplicationFiled: September 5, 2008Publication date: April 2, 2009Applicant: Brother Kogyo Kabushiki KaishaInventor: Takaichiro Umeda

Patent number: 7506955Abstract: Liquid is sent from a liquid retainer to a liquid ejection head via a liquid supply line by pressurization force generated by a pressurization device that is driven by a driver. A method for cleaning a liquid ejection apparatus includes drawing the liquid from the liquid ejection head through a nozzle by a suction device; and obtaining a liquid remaining amount of the liquid retainer. The method further includes determining an operational speed of the driver in correspondence with a result of the calculation; and operating the driver at the determined operational speed when drawing the liquid by the suction device. Thus, liquid is consumed completely without being wasted.Type: GrantFiled: February 13, 2006Date of Patent: March 24, 2009Assignee: Seiko Epson CorporationInventors: Taisuke Yamamoto, Yoshiharu Aruga

Patent number: 7506958Abstract: A printhead maintenance station for maintaining a printhead in an operable condition is provided. The maintenance station comprises an elastically deformable pad having a contact surface for sealing engagement with an ink ejection face of the printhead. The maintenance station also comprises an engagement mechanism for moving the pad between a first position in which the contact surface is sealingly engaged with the face, and a second position in which the contact surface is disengaged from the face. The maintenance station is configured such that the contact surface is progressively contacted with the face during sealing engagement and peeled away from the face during disengagement.Type: GrantFiled: October 11, 2005Date of Patent: March 24, 2009Assignee: Silverbrook Research Pty LtdInventors: John Douglas Peter Morgan, Kia Silverbrook, Christopher Hibbard, Bruce Gordon Holyoake

Patent number: 7506956Abstract: A printing apparatus includes a carry mechanism, a nozzle, an element, a drive signal outputting section, a temperature sensor, a cap, and a controller. The carry mechanism carries a medium. The nozzle performs a moving-and-ejecting operation of ejecting ink toward the medium while moving relative to the medium during an intermission of a carrying operation performed by the carry mechanism. The element performs an ink ejecting operation for causing the ink to be ejected from the nozzle. The drive signal outputting section outputs a drive signal for causing the element to perform the ink ejecting operation. The temperature sensor detects a temperature of the drive signal outputting section or in the vicinity thereof. The cap blocks an ejection opening of the nozzle.Type: GrantFiled: March 6, 2006Date of Patent: March 24, 2009Assignee: Seiko Epson CorporationInventor: Toshiki Usui
