  • Patent number: 7506955
    Abstract: Liquid is sent from a liquid retainer to a liquid ejection head via a liquid supply line by pressurization force generated by a pressurization device that is driven by a driver. A method for cleaning a liquid ejection apparatus includes drawing the liquid from the liquid ejection head through a nozzle by a suction device; and obtaining a liquid remaining amount of the liquid retainer. The method further includes determining an operational speed of the driver in correspondence with a result of the calculation; and operating the driver at the determined operational speed when drawing the liquid by the suction device. Thus, liquid is consumed completely without being wasted.

  • Publication number: 20070170279
    Abstract: A printer including a recording head, a flushing box and a movement mechanism is disclosed. The recording head has a nozzle-forming surface in which nozzle openings are defined and ejects a liquid through the nozzle openings. The flushing box has an opening corresponding to the nozzle openings and is capable of receiving the liquid ejected from the nozzle opening as a waste liquid.
