20100239294 | COLOR-IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, AND COMPUTER PROGRAM PRODUCT - A print control unit causes a secondary-transfer control unit to move a secondary transfer unit apart from an intermediate transfer member, causes a direct-transfer control unit to cause a black image forming unit to form a black image and transfer the black image onto a transfer sheet being conveyed along a conveying path, and causes a positional-alignment control unit to perform positional alignment. | 09-23-2010 |
20100302569 | IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, AND COMPUTER PROGRAM PRODUCT - An image forming apparatus includes a direct-transfer control unit that causes a direct-transfer medium and a first image forming unit that forms a single-color image to transfer the single-color image onto either the direct-transfer medium or a transfer sheet; an indirect-transfer control unit that causes an intermediate transfer medium and a second image forming unit that forms a multi-color image to transfer the multi-color image onto the intermediate transfer medium; a secondary-transfer control unit that transfers the single-color image onto the intermediate transfer medium; a sensor that detects an image on the intermediate transfer medium; and a positional-alignment control unit that calculates, using the sensor, an amount of misalignment of the image and corrects, using a position of an image formed by the first image forming unit as a reference position, positions of images to be formed by the second image forming unit based on the calculated amount of misalignment. | 12-02-2010 |
20100303487 | IMAGE FORMING APPARATUS, IMAGE FORMING METHOD FOR IMAGE FORMING APPARATUS, AND COMPUTER PROGRAM PRODUCT - An image forming apparatus includes a first image forming unit that directly transfers an image onto a transfer sheet; an intermediate transfer member onto which an image is transferred; a secondary image forming unit that transfers an image onto the intermediate transfer member; a secondary transfer unit that transfers the image on the intermediate transfer member onto the transfer sheet; a fixing unit that fixes an image on the transfer sheet at a fixation position; and a guide member that guides the transfer sheet to the fixation position. | 12-02-2010 |
20100303512 | IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, AND PROGRAM - A first alignment control unit causes a secondary transfer control unit to bring a transfer-sheet conveying belt and an intermediate transfer belt into contact with each other so as to transfer an alignment control pattern formed on the transfer-sheet conveying belt onto the intermediate transfer belt, whereby alignment for colors C and K is performed on the intermediate transfer belt, and furthermore a second alignment control unit causes the secondary transfer control unit to separate the transfer-sheet conveying belt and the intermediate transfer belt from each other so as to perform alignment for colors Y, M, and C, whereby alignment is performed for all the colors. | 12-02-2010 |
20100303514 | IMAGE FORMING APPARATUS, IMAGE FORMING METHOD FOR IMAGE FORMING APPARATUS, AND PROGRAM - There are provided an image forming apparatus, an image forming method for the image forming apparatus, and a program that can reduce misalignment among images in all colors. | 12-02-2010 |
20100322679 | Image forming apparaus, and method and computer program product for image forming - An image forming apparatus includes an encoder that detects a first pulse signal relevant to a conveyance velocity of an intermediate transfer belt, an encoder that detects a second pulse signal relevant to a conveyance velocity of a transfer-paper conveying belt, a print control unit that performs feedback control by using a count value of the first pulse signal per unit time and a target conveyance velocity value common between the conveyance velocity of the intermediate transfer belt and that of the transfer-paper conveying belt so that the conveyance velocity of the intermediate transfer belt attains the target value and also performs feedback-control by using a count value of the second pulse signal per unit time and the target value so that the conveyance velocity of the transfer-paper conveying belt attains the target value. | 12-23-2010 |
20110013949 | IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, AND COMPUTER PROGRAM PRODUCT - An image forming apparatus includes a direct transfer control unit that controls a direct transfer unit and a first image forming unit so as to directly transfer an image onto a transfer sheet, an indirect transfer control unit that controls an intermediate transfer unit and a second image forming unit so as to transfer images onto the intermediate transfer unit, a secondary transfer control unit that controls contact/separation between the direct transfer unit and the intermediate transfer unit, a first alignment control unit that corrects an amount of misalignment among the images formed on the intermediate transfer unit, thereby performing a first alignment control process, and a second alignment control unit that corrects an amount of misalignment of an image directly transferred onto the transfer sheet with respect to the image on which the first alignment control process has been performed, thereby performing a second alignment control process. | 01-20-2011 |
20140118326 | IMAGE OUTPUT APPARATUS AND COMPUTER-READABLE RECORDING MEDIUM - An image output apparatus is disclosed that is capable of switching between a normal status and a low power status in which consumption power is lower than that in the normal status. The image output apparatus includes an interface for acquiring an image signal; a signal detector configured to detect a signal at the interface; and a switching controller configured to switch a status from the low power status to the normal status based on a detection result of the signal in the low power status. | 05-01-2014 |
20140130028 | INFORMATION PROCESSING APPARATUS AND NETWORK SYSTEM - An information processing apparatus stores configuration information including sets of version information of modules of firmware in the apparatus; obtains, based on the configuration information, firmware information including sets of version information of modules of firmware in a latest version; compares the sets of version information in the configuration information with those in the firmware information, and, when the sets of version information in the configuration information are not coincident with those in the firmware information, determines that it is possible to update the firmware in the apparatus; downloads the firmware in the latest version; and compares the sets of version information in the downloaded firmware with those in the configuration information, and updates only the module of the firmware in the apparatus for which the version information in the downloaded firmware is different from that in the configuration information. | 05-08-2014 |
