    摘要: A flushing method for a fluid ejecting apparatus that includes a pressure chamber filled with fluid, a pressure generating element on a surface of the pressure chamber that deforms the surface to change the pressure in the pressure chamber, and a nozzle in fluid communication with the pressure chamber that ejects the fluid, the method including repeatedly performing first flushing process a first period; and repeatedly performing a second flushing process with a second period. The flushing processes include causing the pressure chamber to expand into an expanded state, maintaining the expanded state, and contracting the pressure chamber from the expanded state, causing the fluid to be ejected from the nozzle. The amount of fluid ejected from the nozzle in the second flushing process is larger than the amount ejected in the first flushing process.

    摘要: A first evaluation signal includes a first excitation element adapted to excite pressure fluctuation in liquid contained in the pressure chamber and a first ejection element which follows the excitation element after a first time period to eject a first liquid droplet from the nozzle. A second evaluation signal includes a second excitation element adapted to excite pressure fluctuation in liquid contained in the pressure chamber and a second ejection element which follows the excitation element after a second time period to eject a second liquid droplet from the nozzle which is longer than the first time period. The first evaluation signal is supplied to the pressure generating element to measure a first ejected amount of the first liquid droplet. The second evaluation signal is supplied to the pressure generating element to measure a second ejected amount of the second liquid droplet. An ejected amount ratio of the first ejected amount and the second ejected amount is calculated. A natural vibration period of a liquid jetting head based on the ejected amount ratio.

    摘要: A drive signal generator generates a drive signal including a first waveform component for jetting an ink drop to be a micro dot and a second waveform component for jetting an ink drop to be a middle dot. A pressure generating element varies the volume of a pressure generating chamber in accordance with the drive signal to jet an ink drop from a nozzle orifice. An ink drop to be a large dot is jetted from the nozzle orifice when the first waveform component and the second waveform component are consecutively applied to the pressure generating element. A time interval T&mgr;m between an end point of the first waveform component and a start point of the second waveform component is set so as to substantially satisfy the following equation: T ⁢   ⁢ μ ⁢   ⁢ m = n 2 ⁢ Tc here, Tc denotes a natural period of the pressure generating chamber.
