Patent number: 8287098Abstract: A liquid ejection head, a liquid supply apparatus, a liquid ejection apparatus, and a liquid supply method can enable the channel resistance and pressure loss of liquid in the liquid ejection head to be reduced to increase the speed at which liquid is supplied to the nozzles. To achieve this, an ink supply chamber is placed so as to be laminated on a main ink supply chamber. A filter interposed between the main ink supply chamber and the ink supply chamber extends along a surface substantially parallel to a nozzle arrangement plane on which a plurality of nozzles are arranged.Type: GrantFiled: December 23, 2009Date of Patent: October 16, 2012Assignee: Canon Finetech Inc.Inventors: Kayo Mukai, Tomohiro Fujii, Hiroyuki Ishinaga, Yoichi Sonobe

Patent number: 7175252Abstract: An example conventional method of avoiding a printing failure caused by residual bubbles in a print head involves counting from an initiation of a printing operation the accumulated number of print dots formed by the entire print head and, when the count value reaches a predetermined value, executing a recovery operation. Such a conventional method, however, requires the recovery operation to be performed frequently by selecting a threshold value for the worst condition. To solve this problem, the nozzles in the long print head are divided into a plurality of blocks, the accumulated number of print dots is counted for each block, the count value multiplied by a weighting value, which is determined according to the position of the block, is compared with a predetermined threshold, and, when at least one of the weighted count values exceeds the predetermined threshold, the recovery operation is executed.Type: GrantFiled: September 26, 2003Date of Patent: February 13, 2007Assignee: Canon Finetech Inc.Inventor: Yoichi Sonobe

Publication number: 20060268050Abstract: The nozzle faces 22Ks, 22Cs are cleaned with a wiper blade 150 under application of a weak negative pressure to the ink in the nozzles 22Kn, 22Cn. A pressure equal to the atmospheric pressure (the pressure outside the nozzles 22Kn, 22Cn) is applied to the inks in the nozzles 22Kn, 22Cn, and thereby the meniscus Mc and Mk are formed at the ejection outlets 22Ci, 22Ki on the same plane as the nozzle faces 22Cs, 22Ks.Type: ApplicationFiled: May 14, 2006Publication date: November 30, 2006Applicant: CANON FINETECH INC.Inventor: Yoichi SONOBE

Such a conventional method, however, requires the recovery operation to be performed frequently for the following reason. The recovery operation initiation condition has been determined by performing printing operations under a variety of conditions that cause printing failures and which change depending on the liquid chamber structure in the print head and an image pattern being printed, and then selecting a threshold value for the worst condition.Type: ApplicationFiled: September 26, 2003Publication date: October 21, 2004Applicant: CANON FINETECH INC.Inventor: Yoichi Sonobe
