摘要： On a liquid discharge head including an ink discharge surface (6) having rows of ink discharge holes (13) each for discharging different colors of ink, a cleaning roller (7) formed of a cylindrical elastic material touching the ink discharge surface (6) is moved relative to the ink discharge surface (6). This movement causes the pressure inside the ink discharge holes (13) to change and, as a result, the ink (15) inside the ink discharge holes (13) is absorbed. In this way, a ink discharge head, a method for cleaning thereof, and a ink discharge apparatus that do not damage the ink discharge surface (6) with the ink discharge holes (13) and that have improved effectiveness of cleaning the vicinity of the ink discharge holes (13) are provided.

摘要： An ink-jet printer and an apparatus and a method of driving a recording head for an ink-jet printer for suppressing satellite droplets. Two piezoelectric elements are provided for every ink chamber corresponding to each nozzle. Timing of displacement of the piezoelectric elements is adjusted by applying a drive signal for ink droplet ejection to one of the piezoelectric elements and a drive signal for suppressing satellite droplets when a droplet is ejected to the other piezoelectric element. An auxiliary pressure generated by the displacement of the latter piezoelectric element is superimposed on an ejection pressure generated by the displacement of the former piezoelectric element. Trailing of an ink droplet is cut off at an early stage and generation of satellite droplets is suppressed.

摘要： An ink jet printer (100) ejects ink drops from a plurality of nozzles and drops the ink drops on paper P, thus recording information including a character and/or an image in the form of dots based on the ink drops. The ink jet printer (100) has a line head (120) having a driving element for ejecting ink drops from the nozzles. The ink jet printer (100) causes the line head (120) to scan the same portion on the paper P only once in one print and drives the line head (120) to modulate the diameter of a dot by the number of ink drops, using one or a plurality of ink drops for forming one dot.

摘要： An inkjet head includes a head cap for protecting an ink discharge surface of a print head and a cleaning roller for cleaning the ink discharge surface of the print head. The head cap moves relative to and is removably mounted to the print head including the ink discharge surface with an ink discharge hole for discharging ink supplied from an ink cartridge. The cleaning roller is provided at a print head side of the head cap in the longitudinal direction of the print head. By virtue of this structure, it is possible to reduce the size of a printer body. The invention aims at reducing the size of the printer body by providing the cleaning member at the head cap for protecting the ink discharge surface.

摘要： An ink-jet printer and a drive method for driving a recording head of an ink-jet printer are provided for controlling a size and a velocity of an ejected ink droplet. The ink-jet printer includes a droplet outlet orifice through which an ink droplet is ejected, an ink chamber communicating with the outlet orifice, an ink feed duct for feeding ink to the ink chamber, and a piezoelectric element for expanding and contracting the ink chamber in response to an applied voltage. A process for ink ejection includes a first step in which a meniscus in the outlet orifice is retracted towards the ink chamber by expanding the ink chamber, a second step in which the meniscus is moved towards the orifice by filling the chamber with ink, and a third step in which an ink droplet is ejected by contracting the ink chamber. The size and the velocity of the ink droplet ejected in the third step are controlled by controlling a position and a velocity of periodic travel of the meniscus at a start point of the third step.
