Patent number: 8010035Abstract: An image forming apparatus includes a sheet-feeder for feeding a recording sheet from a sheet cassette. Image forming devices are provided for forming a toner image. An image bearer bears a toner image formed by the image forming devices; and a transferring device transfers the toner image on the image bearer to a recording sheet. A sheet amount detector detects the amount of recording sheets in the cassette. A mode controller allows the image forming devices to start their operations before the sheet feeding section conveys a recording sheet when the amount of recording sheets detected by the sheet amount detector exceeds a predetermined reference amount, and allows the image forming devices to start their operations after the sheet-feeding section conveys the recording sheet when the amount of recording sheets detected by the sheet amount detector is smaller than the reference amount.Type: GrantFiled: September 24, 2007Date of Patent: August 30, 2011Assignee: Kyocera Mita CorporationInventor: Katsuji Furushige

Patent number: 7912416Abstract: A printing system comprises a paper path architecture for parallel printing using multiple marking engines. The media path configuration enables all the media feed trays to be located in one place, relative to the marking engines. A cross-over module is located between marking engines. The cross-over module can interleave media sheets that are being transported away from a first marking engine with the sheets being transported to the second marking engine. The cross-over module also includes a straight through path that enables media sheets to be transported directly to a finishing device without going through either marking engine. The marking engines include internal duplex loops such that media can be supplied to each engine in alternate groups. A merge module selectively merges the media which can then be further processed in a finishing transition module prior to communication to a finishing device.Type: GrantFiled: December 20, 2005Date of Patent: March 22, 2011Assignee: Xerox CorporationInventors: Barry Paul Mandel, Steven Robert Moore, Injae Choi, Stan Alan Spencer

Patent number: 7904016Abstract: When an original document is placed on the lift tray, a timer is reset and starts counting a predetermined time. Whether an alignment device is moved to adjust the original documents loaded on the lift tray in, for example, the widthwise direction transverse to the transportation direction is then determined. If a change in the detected width of the original documents is detected, the timer is reset and started again. If there is no change in the detected width of the original documents, a control waits for the timer to time out. If the timer reaches the predetermined time, the lift tray is driven up by the lift motor and rises until the top limit sensor turns on.Type: GrantFiled: June 27, 2008Date of Patent: March 8, 2011Assignee: Kyocera Mita CorporationInventors: Tomohiro Kuwahara, Toshihide Higashimori, Kouichi Kimura, Hidehiro Tabuchi
