The sheet post-processing apparatus, even in the power saving state, is capable of discharging the sheet discharged from the apparatus on the upstream side to the apparatus on the downstream side or a discharge tray. | 12-18-2008 |
20090041522 | SHEET PROCESSING APPARATUS HAVING A SHEET INSERTION FUNCTION, CONTROL METHOD THEREFOR, IMAGE FORMING APPARATUS, AND PROGRAM FOR IMPLEMENTING THE CONTROL METHOD - A sheet processing apparatus which is capable of improving operability while suppressing an increase in apparatus size. In a front cover insertion mode, an insertion sheet for a front cover is inserted into a bundle of sheets on which images have been formed, and in a rear cover insertion mode, an insertion sheet for a rear cover is inserted into the bundle of sheets. Insertion sheets for the front cover and insertion sheets for the rear cover are set with the same orientation in a manual feed tray | 02-12-2009 |
20090103962 | SHEET PROCESSING APPARATUS AND IMAGE FORMING APPARATUS - A sheet processing apparatus includes a folding apparatus | 04-23-2009 |
20090179374 | IMAGE FORMING APPARATUS, SHEET PROCESSING APPARATUS, AND METHOD OF CONTROLLING THE SHEET PROCESSING APPARATUS - An image forming apparatus which enables the user to easily remove a sheet bundle left in the apparatus after a bookbinding-mode job is stopped in the middle of execution thereof. In a bookbinding mode of the apparatus, in a sheet stacking section, a plurality of sheets having images formed thereon are stacked as a sheet bundle; in a gluing section, glue is applied to an end face of the sheet bundle; and in a bonding section, a cover sheet is bonded to the sheet bundle to wrap the sheet bundle in the cover sheet. When a bookbinding-mode job is canceled during execution thereof, in the gluing section, glue is applied to the sheet bundle stacked in the stacking section before the job is stopped, and a discharge section discharges the glue-applied sheet bundle which is neither wrapped nor trimmed. | 07-16-2009 |
20090206538 | POST-PROCESSING APPARATUS, CONTROL METHOD THEREFOR, AND POST-PROCESSING SYSTEM - Provided is a post-processing apparatus which sequentially receives sheets one by one from an image forming apparatus to execute a post-processing on the sheets, including: a first transport device which receives the sheets delivered from the image forming apparatus and transports the sheets; a sheet overlap device which stays the sheets transported by the first transport device and causes another sheet transported sequentially by the first transport device to overlap at least one stayed sheet; a second transport device which transports a plurality of sheets overlapping each other by the sheet overlap device; a plurality of stacking devices capable of stacking a plurality of sheets transported by the second transport device; and a controller which changes control of sheet overlapping caused by the sheet overlap device depending on which stacking device selected from among the plurality of stacking devices the sheets are to be transported to. | 08-20-2009 |
20090283957 | SHEET PROCESSING APPARATUS - A sheet processing apparatus includes an aligning member and a shift conveying unit. The aligning member is movable in a width direction perpendicular to a sheet conveying direction and presses a sheet stack loaded on a sheet processing tray so as to align the sheet stack in the width direction. The unit is provided on the upstream side of the tray and conveys a sheet, shifting the sheet in the width direction. Being shifted by the unit, sheets are loaded at first and second loading positions on the tray. When sheets are loaded at the first loading position, the aligning member is moved to a first standby position corresponding to the first loading position in advance. When sheets are loaded at the second loading position, the aligning member is moved in advance to a second standby position corresponding to the second loading position. | 11-19-2009 |
20090310999 | SHEET POST-PROCESSING APPARATUS, IMAGE FORMING SYSTEM AND POWER SAVING CONTROL METHOD - A sheet post-processing apparatus has a sheet conveying portion which receives and conveys a sheet discharged from an apparatus on an upstream side, and discharges it to an apparatus on a downstream side or a discharge tray, a sheet post-processing portion which carried out post-processing on the sheet, and a power saving control portion which renders the sheet post-processing apparatus into a power saving state, and the power saving control portion maintains electric power supply to the sheet conveying portion, and interrupts electric power supply to the sheet post-processing portion. The sheet post-processing apparatus, even in the power saving state, is capable of discharging the sheet discharged from the apparatus on the upstream side to the apparatus on the downstream side or a discharge tray. | 12-17-2009 |
20100066013 | SHEET STACKING APPARATUS, SHEET PROCESSING APPARATUS AND IMAGE FORMING APPARATUS - A recording material stacking apparatus equipped with a plurality of discharge ports and a plurality of stacking trays can be set to normal mode and large capacity stacking mode each having a different maximum loading capacity. A stacking tray on the upper side has a plurality of lower limit positions and uses a lower limit position located on the upper side when normal mode is selected. On the other hand, it uses a lower limit position located on the lower side when the large capacity stacking mode is selected. The lower limit position located below a stacking tray on the upper side when this large capacity stacking mode is selected exists at a position in which it blocks a lower discharge port of sheets. Selection of the large capacity stacking mode and normal mode is executed according to a result of computation from data input through an input portion. | 03-18-2010 |
20110085839 | IMAGE FORMING SYSTEM AND CONTROL METHOD FOR THE SAME - An image forming system comprises a selection unit for selecting a post-processing apparatus that executes post-processing to a recording medium on which an image is formed from among a plurality of post-processing apparatuses, and a selection limitation unit for determining an insertion apparatus whose supply of the insertion medium to be limited for a selected post-processing apparatus and limiting selection of the insertion apparatus. | 04-14-2011 |
20110133386 | SHEET CONVEYING SYSTEM, CONTROL METHOD THEREFOR, CONTROL PROGRAM FOR IMPLEMENTING THE METHOD, AND STORAGE MEDIUM STORING THE PROGRAM - A sheet conveying system which is capable of preventing a jammed sheet from being mixed with processed sheets, reducing waste in sheets and toners, and further alleviating the user's operations, when jamming has occurred during passing of a sheet between respective sheet conveying devices of upstream and downstream apparatuses. A puncher control section of a puncher as an upstream apparatus of the system issues a passing completion notification as to the passing of a sheet to a staple stacker control section of a staple stacker as a downstream apparatus of the system. Upon reception of the notification, when the staple stacker control section determines that the parameter of auxiliary information of the notification indicates an abnormal discharge of the sheet from the puncher, the staple stacker stops the conveyance of the sheet. | 06-09-2011 |
