Abstract: An image reading device allows an image transmission destination terminal to be designated from a console. The communication unit of the image reading device receives verification data from terminals via a network. The storage unit stores each of the received verification data in association with the terminal which had transmitted the verification data. The user inputs authentication data to the console after setting the document in place. When the authentication data is input, a list of terminals associated with the verification data matching the authentication data is displayed. The user may select from the displayed list, via the console, the transmission destination terminal to which the image is to be transmitted. When the user selects the transmission destination terminal, the reading control unit reads out an image and transmits the image to the selected terminal. The number of terminals displayed as candidates for the image transmission destination can be limited.

Abstract: An image forming apparatus configured to enter in a first power state and a second power state, a reception unit configured to receive a power down command, an operation unit configured to receive an operation of a user, and a control unit configured, if the reception unit receives the power down command, in a case where an elapse time without operating the operation unit is less than a preset time, to execute shift processing for shifting the power state of the image forming apparatus from the second power state to the first power state after elapse of a predetermined time after receiving the data, and in a case where the elapse time without operating the operation unit is equal to or more than the preset time, to execute the shift processing before the elapse of the predetermined time after receiving the power down command.

Abstract: Provided is a data processing method that is capable of high-speed processing without using a large cache memory, while correlating 2-dimensional parameters with a plurality of data without damaging the arrangement rule. Therefore, when there is a continuing M-line parameter after a previously read M-line parameter in a 2-dimensional table that is stored in an external memory 406, the contents of the cache memory 404 are updated with this continuing M-line parameter as the new parameter. When there is no continuing M-line parameter after the previously read M-line parameter in the 2-dimensional table, the contents of the cache memory 404 are updated with the continuing M-line parameter after returning to the starting line of the 2-dimensional table as the new parameter. Such an update rule is maintained even when the band, which is the processing unit, is changed, or even in the progress of band processing.

Abstract: In tandem printing, in accordance with a printing process executed in one printing apparatus, the printing process in the other printing apparatus is automatically changed. The first printing apparatus inputs a third print job including a first print job and a second print job. An image is formed on the basis of the first print job, and on the basis of a result of the image formation, a page with a change amount in the characteristic of a recording medium after printing at a predetermined threshold value or more is detected. The second print job in which the information is changed in accordance with the change amount in the characteristic of the detected page is transmitted to the second printing apparatus.

Abstract: Disclosed are an image forming apparatus, a host apparatus, and a print method thereof. A method includes receiving a one touch print command from a print button provided in the image forming apparatus to print an image of at least one monitor among a plurality of monitors of a host apparatus connected to the image forming apparatus. With this configuration, high quality output products may be provided without any image distortion due to a difference in resolution upon receiving a one touch print command in the multi monitor environment.

Abstract: This invention is directed to a printing apparatus, in which an extension board for PDL processing is added, capable of reducing a waiting time when returning from the power-saving mode upon reception of PDL data. To realize this, upon receiving PDL data before the extension board is ready for use, the apparatus processes the data by using the PDL processing module on the main board. After initializing the extension board, the apparatus uses the added PDL processing module together with that on the main board. Processing the data in this manner makes it possible to start printing the PDL data without consuming a long wait time.

Abstract: An image forming apparatus includes a rotatable image bearing member provided with a mark; a driving portion for rotationally driving the image bearing member; a first detecting portion for detecting speed information of the image bearing member by detecting the mark moved in a predetermined first distance; a second detecting portion for detecting speed information of the image bearing member by detecting the mark moved in a second distance shorter than the predetermined first distance; a filter circuit for suppressing a high-frequency part of an output from the detecting portion and a low-frequency part of an output from the second detecting portion; a calculating portion for calculating a speed of the image bearing member detected from an output from the filter circuit; and a controller for controlling the driving portion so that the calculated speed of the image bearing member is a set speed.

Abstract: Systems and methods are provided for processing a logical page in parallel with graphics for the sheet that are defined in a job ticket. The system includes multiple parallel Raster Image Processors (RIPs) and a control system. The control system receives print data and a job ticket, identifies a graphic that is associated with a logical page and defined in the job ticket, and transmits the logical page to a parallel RIP for processing. The parallel RIP determines page dimensions from the logical page, transmits the page dimensions, and rasterizes the logical page. The control system determines a location for the graphic based upon the transmitted page dimensions, and directs another RIP to rasterize the graphic in order to generate a rasterized graphic in parallel with the RIP that is rasterizing the logical page.

Abstract: Color image data composed of pixels arranged in a matrix wherein colors are expressed in bit rows is created from an acquired document file, and same-resolution binary image data and low-resolution binary image data composed of binary pixels arranged in a matrix are created based on the color image data. A first combining process is performed in which a lower bit value of a predetermined color of the pixels of the color image data is replaced with the value of the corresponding ones of the pixels of the same pixels, and a second combining process is performed in which a lower bit value of a color other than the bit replaced in the first combining process in the pixels of the first combined image data is replaced with the value of the corresponding ones of the pixels of the low-resolution binary image data.

Abstract: A method for reproducing a document is provided. The method includes the following steps: scanning a front side and a back side of an original and accordingly producing a front side image and a back side image; determining a size of the original; comparing the size of the original with a page size; and if the size of the original is determined smaller than one half of the page size, producing one-page image data representing the front side image and the back side image on one single page. An apparatus for reproducing the document is also disclosed.

Abstract: A scanner apparatus comprises a transparent platen having a top side and a bottom side opposite the top side, and an optical sensor unit positioned adjacent the bottom side of the transparent platen. The optical sensor unit scans an image of at least one item placed on the top side of the platen to produce an electronic scanned image of the item. Further, a weight sensor unit is connected to the transparent platen. The weight sensor unit senses the weight of the item placed on the top side of the platen to produce an item weight. A processor is operatively connected to the optical sensor unit and to the weight sensor unit. The processor combines the electronic scanned image of the item and the item weight to produce image and weight data, and the processor outputs the image and weight data.
