Patent number: 7852504Abstract: When the image forming device receives a print job including a print condition in its header, an operation control section extracts the print condition from the header, and makes an inquiry to a server. The server extracts an order table, indicative of a priority based on the extracted print condition, from a setting table in which a priority of sheets has been set in advance in accordance with the extracted print condition, and sends the order table by return to the image forming device. In the image forming device, a tray selection section generates a tray selection signal in accordance with the received order table and a detection signal, outputted from a tray detection section, which functions as sheet storage information of a sheet feeding tray section, so as to send the tray selection signal by return to the sheet feeding tray section.Type: GrantFiled: November 12, 2004Date of Patent: December 14, 2010Assignee: Sharp Kabushiki KaishaInventor: Yoshiaki Tanaka

Publication number: 20100295235Abstract: When image formation processing is in progress using sheets stacked on a given stacking unit and sheets are supplied to another stacking unit, image formation processing continues using the sheets stacked on the other stacking unit. To accomplish this, at the timing when the closing of a feeding source is detected, a control unit (205) determines in step S1001 whether a printer (1000) is executing print processing. In step S1002, the control unit (205) displays a display screen (611) serving as a feeding source selection screen on an operation unit (204). In step S1005, the control unit (205) executes switching processing to the feeding source selected via the display screen (611).Type: ApplicationFiled: May 11, 2010Publication date: November 25, 2010Applicant: CANON KABUSHIKI KAISHAInventor: Yoshiji Kanamoto

Patent number: 7831191Abstract: A printing system includes a first sheet media source dispensing a length of sheet media and a second sheet media source dispensing pre-cut sheets of media. A merging unit is operative to receive the length of sheet media and position pre-cut sheets of media along the same. A marking unit receives and marks images on the length of sheet media as well as the pre-cut sheets positioned thereon. A separating unit is adapted to separate the pre-cut sheets from the length of sheet media. A cutting unit is adapted to divide the length of sheet media into marked and unmarked sheets of media. A sheet receiving unit is operative to receive the marked sheets of media and the pre-cut sheets of media. A method of printing on continuous feed and pre-cut sheet media is also included.Type: GrantFiled: February 1, 2008Date of Patent: November 9, 2010Assignee: Xerox CorporationInventor: Barry P Mandel
