Patent number: 8075120Abstract: An ink jet print head is capable of creating a state where the direction of ink-drop ejection is not likely to be influenced by air currents generated by the ink ejection, and is capable of printing an image without causing the shifting of dots. To this end, air currents generated by the ejection of ink and the interference among the air currents are reduced by blowing out gas in a direction parallel with the direction of the ink ejection. Accordingly, even with a print head that ejects, at high ejection frequency, ink from multiple ejecting openings formed densely, the advancing direction of the ink drops is unlikely to be deflected. As a consequence, a high-quality, uniform image can be outputted.Type: GrantFiled: December 3, 2008Date of Patent: December 13, 2011Assignee: Canon Kabushiki KaishaInventors: Shuichi Ide, Ken Tsuchii, Arihito Miyakoshi, Yasuhiko Osaki, Shuichi Murakami, Hiroshi Arimizu

Patent number: 7992963Abstract: A modular printhead includes an elongate extrusion defining internal passages for carrying air, ink and fixative. The extrusion further defines repeated patterns of holes along its length with each pattern having holes in fluid communication with respective passages. A plurality of printhead modules is serially engaged along the extrusion with respective patterns of holes. Each printhead module defines inlets aligned in fluid communication with respective holes and internal chambers in fluid communication with respective inlets. Each printhead module includes an ink ejection integrated circuit (IC) which is fed the air, ink and fixative from the internal chambers.Type: GrantFiled: September 20, 2007Date of Patent: August 9, 2011Assignee: Silverbrook Research Pty LtdInventors: Kia Silverbrook, Tobin Allen King
