Publication number: 20160067989Abstract: An image formation apparatus includes a conveying unit that conveys a recording medium; a recording head that reciprocates in a direction orthogonal to a conveying direction of the recording medium while the recording medium is being conveyed by the conveying unit, the recording head forming an image on the recording medium; a reception unit that receives scan image data, the scan image data being used to form the image, while the recording head waits in a non-printing region of the recording medium; and a control unit that controls a conveyance distance of the recording medium conveyed by the conveying unit while the recording head waits in the non-printing region. The control of the conveyance distance of the recording medium is determined based on a scan image data reception period of the scan image data, the scan image data reception period being obtained from a communication speed of the reception unit.Type: ApplicationFiled: September 8, 2015Publication date: March 10, 2016Applicant: RICOH COMPANY, LTD.Inventors: Shigeru Yoshigai, Yuuichiroh Tsujiguchi, Hitoshi Sasaki, Takuji Kawaguchi, Keizoh Shigaki

Patent number: 9120321Abstract: An ink jet recording apparatus includes: a container to store ink; a detector to detect a remaining ink amount; a liquid feeding unit to supply the ink to the container; an energy generation unit to cause the ink to be discharged; a storage unit to store correspondence information in which driving information for driving the energy generation unit is associated with each piece of time information indicating a supply time taken to supply the ink; and a setting unit to set new driving information using the correspondence information when an actual supply time is different from the supply time indicated by the time information associated with current driving information among the pieces of time information. The actual supply time indicates a time period from when the liquid feeding unit starts supplying the ink until the detector detects that the remaining ink amount is equal to or higher than a threshold.Type: GrantFiled: April 4, 2014Date of Patent: September 1, 2015Assignee: RICOH COMPANY, LTD.Inventors: Yuuichiroh Tsujiguchi, Namio Ogihara, Hitoshi Sasaki

Patent number: 8998371Abstract: An image forming apparatus includes an image forming device, a conveyance unit, a correction unit, and an attitude controller. The image forming device forms an image on a printing medium. The conveyance unit is disposed opposing the image forming device to convey the printing medium. The correction unit corrects an attitude of a leading edge of the printing medium sent out from the conveyance unit. The attitude controller controls correction of the attitude of the leading edge of the punting medium performed by the correction unit. The attitude controller determines whether or not the correction of the attitude of the leading edge of the printing medium is to be performed, and causes the correction unit to perform the correction when the attitude controller determines that the correction is to be performed.Type: GrantFiled: March 7, 2014Date of Patent: April 7, 2015Assignee: Ricoh Company, Ltd.Inventors: Tomoaki Nakano, Kazuyoshi Matsumoto, Shingo Masaoka, Yasukazu Kitamura, Namio Ogihara, Yoshimitsu Ogura, Makoto Kikura, Kazuyoshi Kondo, Yuuzoh Obata, Norikazu Yanase, Yoshinori Uchino, Gaku Hosono, Takao Otsuka, Seiya Ogawa, Yuuichiroh Tsujiguchi, Masashi Ohnishi
