Liquid ejecting apparatus |
| 摘要 |
A liquid ejecting apparatus includes a liquid ejecting head that ejects liquid in a manifold as liquid droplets from a nozzle opening; a supply path that supplies the liquid to the manifold; a pump unit that is disposed in the supply path and pumps the liquid; and a discharge path that discharges the liquid from the manifold, wherein a flow path resistance of the discharge path from the manifold is smaller than a flow path resistance of the supply path from the pump unit to the manifold. |

1. A liquid ejecting apparatus comprising:
a liquid ejecting head that ejects liquid in a manifold as liquid droplets from nozzle openings; a supply path that supplies the liquid to the manifold; a pump unit that is disposed in the supply path and pumps the liquid to the manifold; and a discharge path that discharges the liquid from the manifold, wherein a flow path resistance of the discharge path from the manifold is smaller than a flow path resistance of the supply path between the pump unit and the manifold to reduce pressure change in the manifold due to difference in number of the nozzle openings ejecting liquid at a time. |
