20100150581 | IMAGE FORMING APPARATUS - Disclosed is an image forming apparatus including a unit in which a replaceable part is loaded, an image forming section to form an image on a recording medium by an operation of the unit, a malfunction detection section to detect a malfunction of the unit or the part and a control section to carry out a control of the image forming apparatus, and when an operation mode to executed an image forming by the image forming section is an image forming mode and when the operation mode which allows a maintenance/replacement of the unit is a maintenance/replacement mode, the control section changes a control of the image forming apparatus according to whether the operation mode when the malfunction was detected by the malfunction detection section is the image forming mode or the maintenance/replacement mode. | 06-17-2010 |
20100225047 | SHEET FEEDING DEVICE AND IMAGE FORMING APPARATUS - There are provided a plurality of sheet feed trays in which sheets are stored, a sheet feeding section which enables a continuous sheet feeding of sheets stored in the above sheet feed tray, and a control section which controls the above sheet feeding section and has an auto tray switch function, and the aforesaid control section obtains information on an amount of sheets stored in the above sheet feed tray, during a continuous sheet feeding from the above sheet feed tray, and judges whether or not the amount of the remaining sheets in the above sheet feed tray satisfies the prescribed condition. In the case where the above prescribed condition is satisfied, the control section stops motion of sheet feeding from the above sheet feed tray while leaving sheets in the above sheet feed tray. | 09-09-2010 |
20100322642 | IMAGE FORMING APPARATUS - An image forming apparatus provided with a sheet feeding tray to store sheets for image forming; a sheet feeding section to feed the sheets form the sheet feeding tray so as to supply the sheets for the image forming; and a control section to individually administer remaining sheets stored in the sheet feeding tray in advance and replenishment sheets replenished when the sheet feeding tray is replenished with the sheets in a state where the sheets stored in the sheet feeding tray in advance is remaining. Whereby, a JOB can be continued or aborted appropriately with reference to information and remaining amounts of remaining sheets and replenishment sheets in one sheet feeding tray, since the information and the remaining amounts are administered individually. | 12-23-2010 |
20100329758 | SHEET SUPPLYING DEVICE, IMAGE FORMING APPARATUS, AND IMAGE FORMING SYSTEM USING THE SAME DEVICE - A sheet supplying device, including a sheet accommodating section which accommodates recording sheets, and is removable from a main body of the sheet supplying device, a locking section which locks the sheet accommodating section within the main body, not to draw out the sheet accommodating section from the main body, a suction conveying section which vacuums the recording sheet accommodated in the sheet accommodating section and conveys the recording sheet, and a suction detecting section which detects the recording sheet vacuumed by the suction conveying section, wherein when the suction conveying section has supplied the recording sheet, if the suction detecting sensor detects the recording sheet, the locking section locks the sheet accommodating section within the main body of the sheet supplying device, and if it does not detect the recording sheet, the locking section releases the sheet accommodating section from the main body. | 12-30-2010 |
20110033217 | Image Forming System and Post-Processing Apparatus - There is described an image forming system, which confirms a finished state of an image at any time during the implementation of the image forming job as needed. The system includes: an image forming section to respectively form images on recording materials; a stacking section to stack the recording materials continuously ejected from the image forming section; an instruction inputting section from which an operator inputs instruction information; an ejecting section to stack a part of the recording materials in such a manner that the operator can pick up stacked recording materials by hand; a controlling section to conduct controlling operations in response to the instruction information, inputted from the instruction inputting section during an implementation of an image forming job including an operation for stacking the recording materials ejected from the image forming section, in order to eject the part of the recording materials onto the ejecting section. | 02-10-2011 |
20110116813 | IMAGE FORMING APPARATUS AND IMAGE FORMING SYSTEM EQUIPPED THEREWITH - An image forming apparatus includes: a sheet conveyance section having a sheet storing member to store sheets that have been aligned in a prescribed placing direction, which conveys a sheet stored in the sheet storing member; an image forming section having an image carrier, which forms an image on the image carrier; an image transfer section which transfers the image formed on the image carrier onto a sheet conveyed by the sheet conveyance section; a winding detection section which detects whether or not the sheet conveyed by the sheet conveyance section is wound around the image carrier; and a controller which controls to instruct an operator to conduct a change operation of the placing direction of the sheets stored in the sheet storing member based on a sheet winding detection signal outputted from the winding detection section. | 05-19-2011 |
20120104689 | SHEET DISCHARGING TRAY DEVICE AND IMAGE FORMING SYSTEM PROVIDED THEREWITH - A sheet discharging tray device includes: a discharging section from which a sheet is discharged; a discharging tray on which the sheet discharged from the discharging section is stacked sequentially; a tray drive section which drives the discharging tray in a tray shift direction that is perpendicular to a sheet discharging direction from the discharging section with reference to a sheet surface; a controller which conducts a tray shift operation that shifts a position of the discharging tray under a condition of the number of sheets stacked on the discharging tray, and a sheet detection section which detects an alignment deviation in the tray shift direction. The controller changes an operation status of the discharging tray when a tray shift operation is conducted and changes a discharging operation of a sheet to the discharging tray, based on a detected result of the sheet detection section. | 05-03-2012 |
