Liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• an ejecting section including
• a nozzle that ejects liquid to be landed on a medium,
• a pressure chamber that communicates with the nozzle, and
• a driving element supplied with a driving signal to generate a pressure variation in liquid in the pressure chamber;
• and
• a driving-signal generation unit that generates the driving signal, wherein
• the driving signal includes a plurality of ejection pulses for ejecting a plurality of droplets from the nozzle during one cycle,
• the plurality of droplets due to the plurality of ejection pulses coalesces before landing on the medium,
• the plurality of ejection pulses includes
• a final ejection pulse that corresponds to a final droplet ejected last from the nozzle among the plurality of droplets and
• a preceding ejection pulse that corresponds to a preceding droplet, among the plurality of droplets, ejected from the nozzle before the final droplet,
• the preceding ejection pulse includes
• a first expansion element that expands the pressure chamber,
• a first expansion-maintaining element that maintains expansion of the pressure chamber by the first expansion element,
• a first contraction element that contracts the pressure chamber expanded by the first expansion element, and
• a first vibration-damping element that, after the first contraction element contracts the pressure chamber, expands the pressure chamber to reduce residual vibration of liquid in the pressure chamber,
• the final ejection pulse includes
• a second expansion element that expands the pressure chamber,
• a second expansion-maintaining element that maintains expansion of the pressure chamber by the second expansion element,
• a second contraction element that contracts the pressure chamber expanded by the second expansion element, and
• a second vibration-damping element that, after the second contraction element contracts the pressure chamber, expands the pressure chamber to reduce residual vibration of liquid in the pressure chamber, and
• a time width of a sum of the second expansion element and the second expansion-maintaining element of the final ejection pulse is longer than a length that is 0.5 multiplied by a natural-vibration cycle of the ejecting section, and is shorter than a length that is 1.0 multiplied by the natural-vibration cycle of the ejecting section.
