Publication number: 20140161477Abstract: A print job is executed such that, in a case where single-sided printing is instructed for some pages and double-sided printing is instructed for some pages among multiple pages for which printing instructions have been given according to a print job, and in a case where it has been determined that a conveyance path is present that is different from the conveyance path for double-sided printing and is for reversing the printing sheets front to rear for discharging, the conveyance path for double-sided printing is used in the double-sided printing and the printing sheets are reversed and discharged through the conveyance path for reversing the printing sheets front to rear for discharging in the single-sided printing.Type: ApplicationFiled: December 2, 2013Publication date: June 12, 2014Applicant: CANON KABUSHIKI KAISHAInventor: Tsuyoshi Kurakata

Patent number: 8332065Abstract: A method includes causing a stacking device having a first stacking unit and a second stacking unit to stack sheets of a small size on the first stacking unit or the second stacking unit and to stack sheets of a large size over the first stacking unit and the second stacking unit, and controlling the stacking of sheets by restricting stacking of the sheets of the large size on the sheet of the small size when the sheets of the small size are stacked on at least one of the first stacking unit and the second stacking unit.Type: GrantFiled: December 14, 2009Date of Patent: December 11, 2012Assignee: Canon Kabushiki KaishaInventor: Tsuyoshi Kurakata

Patent number: 8045189Abstract: A color image forming apparatus and an image output method capable of producing a PDL output without interfering with the execution of a calibration procedure is provided. A main controller rasterizes PDL data from a network on a DRAM as image data. The main controller determines whether or not a calibration procedure is being executed. If it is determined that the calibration procedure is being executed, a production of a PDL image output is put in a queue until the calibration procedure is completed. If it is determined that the calibration procedure is not being executed, the image data on the DRAM is transferred to a printer portion at an appropriate timing so that the printer portion may produce a printed page of the image data.Type: GrantFiled: December 9, 2010Date of Patent: October 25, 2011Assignee: Canon Kabushiki KaishaInventor: Tsuyoshi Kurakata

Publication number: 20110052290Abstract: When executing the second image forming process for a sheet having undergone the first image forming process, feeding of the sheet for an image forming process different from the second image forming process needs to be prevented. To accomplish this, an image forming apparatus includes a control unit that executes the first image forming process to form an image on a sheet fed from one of feeding units, and a designation unit that designates, from the plurality of feeding units, a feeding unit used for the second image forming process to be executed for the sheet having an image formed in the first image forming process executed by the control unit. When the sheet is set in the feeding unit designated by the designation unit, the control unit restricts feeding of the set sheet for an image forming process different from the second image forming process.Type: ApplicationFiled: August 5, 2010Publication date: March 3, 2011Applicant: CANON KABUSHIKI KAISHAInventor: Tsuyoshi Kurakata
