Patent ID: 8434846

Claim:
A liquid ejecting apparatus comprising: a liquid ejecting head which ejects a liquid from a nozzle to an ejection medium; a heating unit which heats and dries the liquid ejected to the ejection medium, wherein the heating unit is separate from the liquid ejecting head so as to be able to heat and dry the ejected liquid; a temperature measuring unit which is disposed at a predetermined region near the liquid ejecting head and measures a temperature of the predetermined region; a temperature calculating unit which calculates a temperature of the liquid based on a temperature measurement of the temperature measuring unit, an amount of time elapsed after operation of the heating unit and an outside ambient temperature; and a driving waveform correcting unit which corrects a head driving waveform of the liquid ejecting head on the basis of a calculation result by the temperature calculating unit, wherein a viscosity of the liquid is increased when the temperature of the liquid is low such that that a corrected head driving waveform is increased relative to the reference head driving waveform, and wherein the viscosity of the liquid is decreased when the temperature of the liquid is high such that that the corrected head driving waveform is decreased relative to the reference head driving waveform.
