20090142088 | Image forming apparatus and image forming system - An image forming apparatus of the present invention is arranged so that plural sheets of paper are conveyed to a main conveying path and a sub-conveying path at the time of double-side image formation. In performing double-side image formation jobs on plural sets of sheets of paper, a sequence control section makes a change of sequences for image formation so that a post-process for the previous job can be performed during image formation of the next set. With this, in performing double-side image formation jobs on plural sets of sheets of paper in an image forming system constituted by an image forming apparatus and a post-processing apparatus, images can be formed in succession without suspending image formation of the next set to allow post-processing time for the previous set. This makes it possible to achieve a system with high job efficiency. | 06-04-2009 |
20100296829 | ENGINE SYNCHRONIZATION WITH A SMALL DELTA TIME BETWEEN ENGINES - A method of synchronizing the timing of a plurality of physically coupled print engines using a small delta time increment. According to the first mode of practice, the second electrophotographic module, designated as E | 11-25-2010 |
20100329724 | MOTOR CONTROL APPARATUS AND IMAGE FORMING APPARATUS - A motor control apparatus that controls a DC motor includes a detection unit configured to detect angular speed of the DC motor, a driven member configured to be driven by the DC motor, and a control unit configured to increase, when starting to drive the DC motor, a control value for controlling driving of the DC motor from a first control value to a second control value at a predetermined increase rate, wherein the control unit detects a start-up characteristic of the DC motor based on a detection result of the detection unit, and corrects the first control value or the increase rate according to a result of comparing a detected start-up characteristic and a predetermined start-up characteristic such that the start-up characteristic of the DC motor becomes closer to the predetermined start-up characteristic. | 12-30-2010 |
20110150520 | IMAGE FORMING APPARATUS AND IMAGE FORMING SYSTEM - An image forming system including first and second image forming apparatuses that includes a first image forming unit configured to form an image on a first surface of recording paper, a discharging unit configured to discharge the recording paper on which the image is formed by the first image forming unit to the second image forming apparatus, a second image forming unit configured to form an image on a second surface of the recording paper discharged by the discharging unit from the first image forming apparatus, and a correction unit configured to correct adjustment timing of the image forming system as a whole so that first adjustment timing for performing an adjustment operation of an output image formed by the first image forming unit and second adjustment timing for performing an adjustment operation of an output image formed by the second image forming unit accord with each other. | 06-23-2011 |
20110236050 | METHOD FOR OPERATING AN IMAGE-FORMING DEVICE AND AN IMAGE FORMING DEVICE FOR APPLICATION OF THE METHOD - The present invention relates to a method for selectively removing magnetically attractable toner particles from an image-forming device, the image-forming device comprising a cleaning magnet system, configured to provide an activatable second magnetic field, the method comprising a step of switching the image-forming device into a cleaning mode, the cleaning mode comprising the steps of stopping the toner supply to the image-recording medium, rotating the rotatable sleeve in a second direction, opposite to the first direction, such that the magnetically attractable toner particles are transported out of the developing zone towards the cleaning magnet system, and activating the second magnetic field so as to remove the transported magnetically attractable toner particles from the rotating sleeve of the developing element. The invention also relates to an image-forming device for performing the method. | 09-29-2011 |
20110318041 | CONTROLLING SHEET SYNCHRONIZATION IN A DIGITAL PRINTING SYSTEM - A calibration procedure for the synchronization of photoreceptor belt seams of tandem marking devices at system cycle-up. The procedure allows for images projected upon equivalent image panels relative to the belt seams of the tandem engines to be printed on the same sheet. The successive image panels on each belt are of relatively equal distance from the respective belt seams. Thus there is less frequency of the need to skip pitches in the printing operation to avoid either imaging on a belt seam or having the sheet arrive outside the input timing window for second engine sheet registration. | 12-29-2011 |

20080219688 | IMAGE FORMING APPARATUS WITH REDUCED START-UP TIME - A disclosed image forming apparatus forming a visible image on a recording medium includes: a functional element required for an image forming operation; a first control unit controlling the functional element; an input unit inputting an external instruction; and a second control unit communicating with the first control unit about information on the image, performing a process in accordance with the instruction input via the input unit, and outputting a return signal for starting the functional element required for performing the process in accordance with the instruction. | 09-11-2008 |
20080267653 | IMAGE FORMING APPARATUS - In an image forming apparatus that outputs a reference clock, divides the outputted reference clock based on a set multiple, and generates an image clock based on the division, a width of a synchronization signal that indicates dynamic deviation characteristics is detected, and the multiple is set in accordance with the detected width of the synchronization signal. | 10-30-2008 |
20080310874 | Image forming apparatus - An image forming apparatus including a controller configured to control each unit of the image forming apparatus, and an engine to which a startup instruction is sent from the controller and a plurality of peripheral devices is connected in series. Power is supplied to the controller and the engine separately, and further supplied to the plurality of peripheral devices from the engine. The engine independently sends startup instructions to the plurality of peripheral devices. | 12-18-2008 |
