Patent ID: 7959249

Claim:
A liquid-ejecting method comprising the steps of: supplying a continuous current to each of a plurality of heating elements operatively associated with a respective plurality of liquid cells in a liquid-ejecting head and heating each of the plurality of liquid cells therein that contains an ejection medium that is liquid at ambient temperature to generate heat so that at least the temperature of each of the liquid cells is constantly maintained at a bias temperature within the range of 25° C. to 70° C., the ejection medium having a viscosity suitable for ejection at the bias temperature, the ejection medium including a modifier so that the viscosity of the ejection medium at the bias temperature is optimized; and driving one or more heat generating energy units respectively associated with the plurality of liquid cells to supply ejection heat energy to the ejection medium in corresponding liquid cells so that the ejection medium is ejected from corresponding nozzles in a droplet form, wherein, each liquid cell is constantly maintained at the bias temperature irrespective of whether the corresponding heat energy unit is driven, and the step of supplying the continuous current is performed independently of the step of driving of the one or more energy units.
