Patent number: 8596733Abstract: In a liquid ejecting apparatus, when a ON/OFF detector detects that power of the liquid ejecting apparatus is switched to an ON state from an OFF state, a controller controls a liquid transfer unit such that liquid is transferred to a tank of which residual amount of liquid is smaller from a tank of which residual amount of liquid is larger based on the residual amount of liquid in a first tank detected by the first liquid residual amount detector and the residual amount of liquid in a second tank detected by the second liquid residual amount detector.Type: GrantFiled: November 24, 2010Date of Patent: December 3, 2013Assignee: Seiko Epson CorporationInventors: Yasushi Akatsuka, Nobuhito Takahashi

Patent number: 8287064Abstract: A liquid ejecting apparatus includes a first liquid containing unit containing a liquid therein and a second detachable liquid containing unit containing a liquid therein and having a liquid containing volume smaller than that of the first liquid containing unit. A communication passage communicates the first liquid containing unit with the second liquid containing unit. The first and second liquid containing units are reciprocally replenished with the liquid by a liquid replenishing unit through the communication passage. When the liquid is replenished from the first or second liquid containing units to the other, a control unit controls the liquid replenishing unit to replenish the liquid from the one liquid containing unit to the other liquid containing unit, until the liquid contained in the one liquid containing unit reaches a predetermined amount smaller than the liquid containing volume of the second liquid containing unit.Type: GrantFiled: September 30, 2009Date of Patent: October 16, 2012Assignee: Seiko Epson CorporationInventors: Yasushi Akatsuka, Hitotoshi Kimura

Patent number: 7871156Abstract: An ink cartridge for an ink jet printer having a housing having at least one wall. The ink cartridge further has at least two ink chambers for containing different ink accommodated in the housing. Ink supply ports are formed in one wall of the housing within each of the ink chambers. Each of the ink supply ports has an inner opening and an outer opening. The distance from the inner opening of a first ink supply port to that of a second ink supply port adjacent to the first ink supply port is different from a second distance from the outer opening of the first ink supply opening to that of the second ink supply port.Type: GrantFiled: October 19, 2007Date of Patent: January 18, 2011Assignee: Seiko Epson CorporationInventors: Minoru Usui, Satoshi Shinada, Takahiro Naka, Hisashi Miyazawa, Takeo Seino, Hisashi Koike, Takao Kobayashi, Masahiro Kanai, Yasuko Hirano, Yasushi Akatsuka, Takayuki Iijima, Noriaki Okazawa, Hitoshi Matsumoto, Yasuhiro Ogura

Publication number: 20100060682Abstract: A liquid ejecting apparatus includes a head that includes a plurality of nozzles disposed for each color of liquids and ejects liquids from the plurality of nozzles onto a medium and a control unit that forms a nozzle test pattern for testing defective liquid-ejection of a test target nozzle with one from the plurality of nozzles set as the test target nozzle. The control unit performs either a first process in which the nozzle test pattern is formed by having liquids ejected from the test target nozzle and a different nozzle, which is different from the test target nozzle, from the plurality of nozzles land on the medium in an overlapping manner or a second process in which the nozzle test pattern is formed by having only the liquid ejected from the test target nozzle land on the medium in accordance with the type of the medium.Type: ApplicationFiled: September 4, 2009Publication date: March 11, 2010Applicant: SEIKO EPSON CORPORATIONInventor: Yasushi Akatsuka
