Patent ID: 8434842

Claim:
A liquid ejecting apparatus comprising: a liquid ejecting head which includes a nozzle ejecting a liquid, a pressure chamber communicating with the nozzle, and a pressure generation unit applying pressure variation to the liquid of the pressure chamber and which ejects the liquid from the nozzle by an operation of the pressure generation unit; a driving control unit which generates a driving signal containing an ejection pulse used to eject the liquid from the nozzle and controls driving of the pressure generation unit; and a movement unit which moves the liquid ejecting head relative to a landing target, wherein a first liquid and a second liquid different from the first liquid are ejected, wherein the driving signal includes a first signal used to eject the first liquid and not used to eject the second liquid and a second signal used to eject the second liquid and not used to eject the first liquid, wherein the first and second signals each include a liquid-kind ejection pulse having a first variation section in which a potential is varied in a first direction, a hold section in which a termination potential of the first variation section holds for a given time, and a second variation section in which the potential is varied in a second direction opposite to the first direction, wherein the second variation section includes a first variation component in which the potential is varied in the second direction from the termination potential of the first variation section, an intermediate hold component in which the termination potential of the first variation component holds for a given time, and a second variation component in which the potential is varied in the second direction from the termination potential of the first variation component, wherein a potential inclination of the second variation component in the liquid-kind ejection pulse of the first signal is gentler than a potential inclination of the first variation component, wherein a potential inclination of the second variation component in the liquid-kind ejection pulse of the second signal is steeper than the potential inclination of the first variation component, and wherein a ratio of the potential of the intermediate hold component to the potential of the hold section is larger in the liquid-kind ejection pulse of the second signal than in the liquid-kind ejection pulse of the first signal.
