Patent number: 7775622Abstract: In an inkjet printing apparatus which performs printing on a printing medium using an inkjet printhead for discharging ink, preliminary discharge, where ink discharge irrespective of printing is performed at the time of print execution, is performed under a predetermined condition. The printing apparatus includes a control section and a setting section. The control section executes a preliminary discharge by the printhead, which has a plurality of discharge orifices, before a predetermined time has elapsed since a latest preliminary discharge, in printing of an image, and the setting section sets the predetermined time. The setting section obtains an elapsed time after executing the preliminary discharge until a discharge failure occurs in any one of the plurality of discharge orifices, and sets the elapsed time as the predetermined time.Type: GrantFiled: March 3, 2009Date of Patent: August 17, 2010Assignee: Canon Kabushiki KaishaInventors: Kazuo Suzuki, Daigoro Kanematsu, Rie Takekoshi, Mitsutoshi Nagamura, Naoko Baba

Publication number: 20100156978Abstract: The present invention relates to a print apparatus for performing a print by a scan of a print head with heaters generating thermal energy for ejecting ink. A temperature of the print head is detected before the scan of the print head, and when the detected temperature exceeds a threshold temperature, the print head is waited. Information relating to the cumulative number of drives of the heater in the print head is acquired and based upon this information, the threshold temperature is changed to a lower temperature as the cumulative number of the drives is the larger. An excessive temperature rise of the head is restricted and also a throughput reduction is reduced as much as possible.Type: ApplicationFiled: December 9, 2009Publication date: June 24, 2010Applicant: CANON KABUSHIKI KAISHAInventors: Taku Yokozawa, Kazuo Suzuki, Yosuke Ishii, Kazuhiko Sato

Publication number: 20100156977Abstract: An object of the present invention is to provide a printing apparatus and a printing method even with a variation in the temperature of a print head, thus keeping the quality of images resulting from printing high. Adjustment patterns used to adjust the difference in ink ejection timing between ink ejected in a forward direction and ink ejected in a backward direction during scanning are printed at a plurality of different temperatures. Adjustment values for the ink ejection timing at the respective temperatures are selected from the adjustment patterns. Then, the correction value for the ink ejection timing is calculated from the adjustment values based on the temperature detected by the detection device. Printing is then performed with the difference in ink ejection timing between the ink ejected in the forward direction and the ink ejected in the backward direction during scanning, adjusted based on the correction value.Type: ApplicationFiled: December 8, 2009Publication date: June 24, 2010Applicant: CANON KABUSHIKI KAISHAInventors: Daigoro Kanematsu, Kazuo Suzuki, Taku Yokozawa, Satoshi Hayashi, Yuhei Oikawa

Patent number: 7367643Abstract: For a serial inkjet printing apparatus that performs printing by employing ink having different properties, the occurrence of smear is prevented without decreasing the printing speed more than necessary. A high duty area, i.e., a unit area for which a large amount of ink is applied, is detected in a preceding printing medium. Then, while taking into account the scanning direction (ink application order) in which the detected high duty area has been printed, the period until the following printing medium is permitted to contact the high duty area is determined. Then, during printing of the following printing medium, the printing operation is delayed, so that, within the determined period of time, the following printing medium does not contact the high duty area of the preceding printing medium.Type: GrantFiled: June 8, 2006Date of Patent: May 6, 2008Assignee: Canon Kabushiki KaishaInventors: Tomomi Furuichi, Daigoro Kanematsu, Mitsutoshi Nagamura, Takao Ogata, Kazuo Suzuki

Patent number: 7347519Abstract: A printing apparatus is provided which can utilize a power supply to its maximum capacity without overly degrading throughput. A print area that can be printed in one scan of a print head is divided into a plurality of blocks. The number of data indicating print in each block is detected. Then the detected value is compared with a plurality of thresholds. Based on a result of the comparison, a scan speed of the print head and the number of scans are determined. This arrangement allows for a selection of an optimum printing method from among a plurality of scan speeds and a plurality of divided printing modes even when an image that may cause a CURRENT in excess of the maximum power supply capacity to flow is printed. With this printing apparatus it is possible to execute printing fully utilizing the power supply capacity without overly degrading throughput.Type: GrantFiled: May 19, 2005Date of Patent: March 25, 2008Assignee: Canon Kabushiki KaishaInventors: Mitsutoshi Nagamura, Daigoro Kanematsu, Naoko Baba, Kazuo Suzuki, Tomomi Furuichi
