    • A host computer transmits raster information to a multi-color ink jet printer. The printer includes a printhead connected with an electrical processor. The printhead includes a plurality of arrays of ink jetting heaters. Each array of ink jetting heaters corresponds to a different color ink to be jetted onto the print medium, and is offset relative to an adjacent array of ink jetting heaters in an advance direction of the print medium. First raster information for a first raster is transmitted from the host computer to the electrical processor of the printer. The first raster information is associated with a first array of ink jetting heaters. The print medium is printed on by selectively actuating the ink jetting heaters of the first array of ink jetting heaters, using the first raster information. After the first printing step, second raster information for a second raster is transmitted to the electrical processor. The second raster information is associated with the first array of ink jetting heaters. After the first printing step, third raster information for the first raster is transmitted to the electrical processor. The third raster information is associated with a second array of ink jetting heaters. After the second and third transmitting steps, the print medium is printed on by selectively actuating the ink jetting heaters of the first and second arrays of ink jetting heaters, respectively using the second and third raster information.
    • 主计算机发送的光栅信息,以多色喷墨打印机。 该打印机包括在电处理器与连接的打印头。 所述打印头包括喷墨加热器的阵列中的多个的情况。 喷墨加热器的每个阵列对应于要喷射到打印介质上不同颜色的墨,并相对于在墨的相邻阵列中的打印介质的前进方向喷射在加热器偏移。 用于第一网格的第一光栅信息是从主计算机到打印机的电处理器的反式mitted。 第一光栅信息与喷墨加热器的第一个阵列相关联。 打印介质被选择性地致动的喷墨喷墨加热器的第一个阵列的加热器,使用所述第一网格信息打印。 第一打印步骤之后,用于第二网格的第二光栅信息是反式mitted到电处理器。 所述第二光栅信息与喷墨加热器的第一个阵列相关联。 第1印刷工序后,对于第一格第三光栅信息是反式mitted到电处理器。 第三栅极信息与喷墨加热器的第二阵列相关联。 之后的第二和第三发送步骤中,打印介质被选择性地致动的喷墨油墨的喷墨加热器,分别使用第二和第三栅极信息的第一和第二阵列的加热器上印刷。

    • A two-wire former of a paper-making machine has the following characteristics: (1) two continuous, loop-shaped wires (1, 2) form together an inlet gap for the paper pulp suspension; (2) a sheet forming zone has a section in which both wires are guided parallel to each other; (3) a plurality of guide rollers are arranged inside and outside both wire loops; (4) a roller (3, 4) associated to each wire loop deflects the associated wire at the beginning of the parallel section; (5) at least one of both inlet rollers (3, 4) has a circumferential area that forms no closed surface (forming roller). According to the invention, (6) both wires runs on the paper pulp-bearing section in a substantially horizontal direction; (7) the top wire is separated from the bottom wire by a separating suction box (8) with a curved surface; (8) the dewatering element (7.1) that follows the forming roller on the same side of the wire is provided with elastically suspended dewatering strips (7.3).
