Patent number: 8469474Abstract: Each of four areas of 2×2 in one pixel has four sub areas and the four sub areas correspond to four nozzle arrays A to D. In the sub area of each area, information showing what nozzle array is used for a print of the area is defined. The sub area filled in black shows performing therein a print of a dot using nozzles in the nozzle array corresponding to the sub area. In this way, the dot arrangement pattern has information showing the nozzle array to which nozzles used for printing an area belong, for each area. Therefore, without executing the particular data allocation processing such as mask processing, the allocation of the dot data to the plurality of nozzle arrays can be carried out with a simple arrangement.Type: GrantFiled: June 10, 2010Date of Patent: June 25, 2013Assignee: Canon Kabushiki KaishaInventors: Koichiro Nakazawa, Hideaki Takamiya, Noribumi Koitabashi

Patent number: 8313188Abstract: An ink jet printing apparatus according to the present invention includes a dryer configured to dry ink on a print medium. The dryer includes a heating unit configured to heat air in the dryer, and an outside air adjustment mechanism configured to adjust the amount of outside air introduced into the dryer. When the outside air adjustment mechanism is controlled so that the outside air introduction amount is increased, before the control of the outside air introduction amount, the heating unit is controlled so that heated air heated by the heating unit is preheated to a second target temperature higher than a predetermined first target temperature for a normal operation. Even if the outside air introduction amount is actually increased to temporarily reduce the temperature of heated air, the temperature of the heated air can be maintained at a value required for sufficient drying.Type: GrantFiled: September 7, 2010Date of Patent: November 20, 2012Assignee: Canon Kabushiki KaishaInventors: Kentarou Muro, Tsuyoshi Kanke, Riichi Saito, Noribumi Koitabashi

Patent number: 8157349Abstract: A method of a cleaning of an ejection face by supplying a head liquid on the face of an inkjet head provided with ink ejection openings and then by performing a wiping operation. Sufficient cleaning is achieved by appropriately specifying relative relationships among the surface tensions of the face, the ink and the head liquid, and by efficiently and surely removing an ink residue from the face. By supplying the head liquid to the ink residue on the face, both are mixed with each other, and thereby the ink residue is incorporated into the head liquid. In this respect, by using the ink and the head liquid both having a surface tension higher than that of the face, a wetting of a dissolved matter of the ink residue with respect to the face is reduced, and the dissolved matter of the ink residue is smoothly moved by the wiping operation.Type: GrantFiled: June 25, 2007Date of Patent: April 17, 2012Assignee: Canon Kabushiki KaishaInventors: Mikio Sanada, Nobuyuki Matsumoto, Noribumi Koitabashi
