  • Publication number: 20160114599
    Abstract: In an inkjet printer, there has been a problem in that a recording medium is charged with electricity due to friction and separation at the time of conveyance of the recording medium, and ink mist is attracted to a portion charged with electricity to have an unexpected pattern to be recorded. In view of this problem, static electricity generated on the recording medium is removed by providing a carriage with an ionizer for generating a positive ion and an ionizer for generating a negative ion and generating the ions at the time of scan of the carriage. Through the arrangement of the ionizers for generating the ions of both polarities, namely, the positive ion and the negative ion, on the carriage, and on/off control on the ions to be generated in each scan, an amount of ions to be supplied per unit area of the recording medium can be made uniform, with the result that the static electricity can be removed efficiently.

  • Publication number: 20160101634
    Abstract: When an inkjet printer includes suction means for sucking the outside air into the inkjet printer, a heated recording medium is rapidly cooled by the air flowing in a vicinity of a discharge port for the recording medium. This causes fluctuations in surface temperature, resulting in degraded image quality. Accordingly, the inkjet printer has both a configuration capable of directly sucking, into a carriage, the outside air sucked into an apparatus, and a configuration of preventing the air from passing through an inside of the carriage. Thus, a temperature of the inside of the carriage can be reduced effectively. In order to prevent a reduction in temperature of the recording medium in the vicinity of the discharge port, a heater is arranged so as to increase a heating capacity of heating. Through temperature control on the heater based on a temperature of a region that is easily reduced in temperature, a local reduction in temperature of the recording medium is suppressed.

  • Patent number: 9180660
    Abstract: The present invention relates to an ink jet recording apparatus including a recording head including a plurality of energy generation elements configured to generate thermal energy. The ink jet recording apparatus includes a specification unit and a control unit. The specification unit specifies a pulse width upper limit value of a prepulse during a recording operation based on a minimum pulse width by which ink is discharged by applying a drive pulse to the energy generation elements and a temperature of the recording head during the recording operation. The control unit controls the energy generation elements to be driven using a drive pulse of a prepulse with a pulse width equal to or less than the pulse width upper limit value.

  • Patent number: 9162462
    Abstract: An embodiment of the present invention provides a wiping method capable of preventing a problem such as color mixing or a discharge failure in a wiping operation during the reciprocating motion of a carriage. According to the embodiment, one or a plurality of orifice arrays out of a plurality of orifice arrays included in a printhead are wiped by making a sheet-like wiping member contact to the orifice surface of the printhead. After that, the wiping member is separated from the orifice surface of the printhead, and the used wiping member is wound. Then, the wiping member is made to contact to the orifice surface of the printhead again, and the next one or more orifice arrays are wiped.

  • Patent number: 9114607
    Abstract: Provided are an inkjet printing apparatus, whereby pulse drive periods and a pause period can be adjusted so as to fall within predetermined periods, while the volume of ink to be ejected is ensured, and a heat generating element driving method therefor. For the inkjet printing apparatus, a pulse signal drive period for a pulse driven previously, a pulse signal drive period for a pulse driven subsequently and a pause period are set to perform ejection of ink droplets one time. When the ejection period exceeds the threshold value, the pulse signal drive period for the pulse driven subsequently and the pause period are reduced to adjust the ejection period to be equal to or lower than a threshold value.

  • Patent number: 9108409
    Abstract: The invention prevents inconveniences from being caused by ejection failure and unintended mixing of different colors. To this end, the invention performs preliminary ejection of ink after a wiping action to sweep mist adhering to a face of a printing head, in which an ejection opening is formed. Moreover, the amount of ink to be wastefully consumed by the preliminary ejection after the wiping is reduced. To this end, the number of preliminary ejections is regulated. The degree of adherence of mist to the ejection-opening-formed face depends on the amount of printing (the number of printed sheets, the number of ink ejections for printing, or the like). So, at the time of the preliminary ejection after the wiping, the number of ink ejections in the preliminary ejection is regulated in accordance with the amount of printing that has been done since the last wiping action.

  • Publication number: 20150217494
    Abstract: A molding die is devised to suppress the formation of a fragile layer, thereby ensuring stable production of a resin molded body having remarkably improved adhesion of a plating film. A plurality of stepped parts are formed so as to be spaced apart from each other on a second die surface which molds a back surface on the side opposite to a design surface to which metal plating is to be applied, along the main flowing direction of a molten resin and in a direction crossing the main flowing direction. Since the flow of the molten resin changes due to the stepped parts and the influence thereof extends even to the vicinity of the design surface, the formation of a fragile layer is suppressed.

  • Patent number: 9050794
    Abstract: An inkjet printing apparatus which performs printing by performing scanning using a print head has a problem in that quality of an image of a ruled line is degraded when ink is not ejected for a certain period of time. To address this problem, control is performed such that power for driving the print head for unit regions including pixels having a ruled-line attribute becomes higher than power for driving the print head for unit regions which do not include the pixels having the ruled-line attribute. By this, a high-quality ruled-line image may be printed.
