    摘要： In order to reduce emission noise, a recording apparatus uses a cycle controller to variably control a transmission cycle, when transmitting recording data to the recording head, and a head controller to control the recording head based on the controlled transmission cycle and the recording data. By varying the data transfer cycle of data to the recording head, the recording apparatus of the present invention makes it possible to suppress a rise in radiation noise peak levels due to overlapping of radiation noise spectra, which in turn weakens the strength of the electric field at certain cycles and makes it possible to reduce radiation noise levels.

    摘要： This invention provides an image print apparatus capable of quickly reducing, with a low-cost arrangement, charges accumulated in a capacitor used for reducing variations in printhead voltage, and a control method thereof. After a head power supply VH which supplies power to the printhead is turned off, the print element of the printhead is so driven as not to discharge ink.

    摘要： A liquid discharge head comprises a plurality of main discharge ports arranged at predetermined intervals, at least one sub-discharge port arranged in the arrangement direction of the main discharge ports on both end sides of the arrangement direction of main discharge ports at intervals larger than the intervals of the main discharge port arrangement, a plurality of liquid chambers having these plural discharge ports open thereto, a common liquid chamber having these liquid chambers communicated therewith, and liquid being supplied thereto, and a plurality of discharge energy generating units provided for each of the liquid chambers corresponding to the main discharge ports and the sub-discharge ports to generate discharge energy utilized for discharging liquid from the main discharge ports and the sub-discharge ports. With the liquid discharge head thus arranged, bubbles residing on both end portions of the common liquid chamber are exhausted together with liquid thus exhausted from the sub-discharge ports, hence making it possible to effectively prevent drawback, such as color mixture, that may occur when different kinds of liquid enter the interior of liquid discharge head from the sub-discharge ports at the time of executing recovery process of the liquid discharge head which is performed by the overall suction operation.

    摘要： A recording apparatus includes a recording head. The recording head is provided with a recording device string made up of a plurality of recording elements. The recording device string is arranged at a specified angle in relation to the direction perpendicular to the direction in which the recording head moves. A plurality of recording elements is divided into a plurality of blocks and sequentially driven in units of blocks at a specified interval. When recording is performed from a position other than an end of the recording device string, the drive sequence of the blocks is changed. The block including the recording element corresponding to a recording start position is first driven and recording data is read with the effective use of a signal line in a data bus.
