  • INKJET PRINTING APPARATUS AND METHOD OF CONTROLLING THE SAME
    Publication number: 20100302297
    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.

  • PRINTING APPARATUS AND PRINTING METHOD
    Publication number: 20100156973
    Abstract: The present invention has an object to provide an inkjet printing apparatus that can realize both high quality image formation and improvement of a device life caused by the reduction of a mist amount of a processing liquid. The present invention is provided with a control unit that can independently control an ink ejection condition in an ink ejection unit and a processing-liquid ejection condition in a processing-liquid ejection unit. The control unit controls the ejection condition in each ejection unit so that the mist amount of the processing liquid ejected from the processing-liquid eject unit is smaller than that of the ink ejected from the ink eject unit.

  • INKJET PRINT APPARATUS AND INKJET PRINT METHOD
    Publication number: 20100156978
    Abstract: The present invention relates to a print apparatus for performing a print by a scan of a print head with heaters generating thermal energy for ejecting ink. A temperature of the print head is detected before the scan of the print head, and when the detected temperature exceeds a threshold temperature, the print head is waited. Information relating to the cumulative number of drives of the heater in the print head is acquired and based upon this information, the threshold temperature is changed to a lower temperature as the cumulative number of the drives is the larger. An excessive temperature rise of the head is restricted and also a throughput reduction is reduced as much as possible.

    Patent number: 7633243
    Abstract: In a headlamp luminance controlling device, a CPU 21 first decides a luminance factor D based on a state of each switch 10 to switch 12 and a signal from a sensor 13. The CPU 21 determines an initial value of a PWM duty ratio S from the luminance factor D with a load current Ap as a default value (rated current A0). The CPU 21 starts the initial driving of a headlamp HL using the duty ratio S. The CPU 21 then determines the luminance factor D based on the state of each switch 10 to switch 12 and the signal from the sensor 13. Next, the CPU 21 determines the PWM duty ratio S based on the luminance factor D and the load current Ap detected by the headlamp current detector 23. The CPU 21 drives the headlamp HL using the PWM duty ratio S.
