Abstract
A liquid discharge head includes a nozzle to discharge a liquid, an individual chamber communicating with the nozzle, a supply channel communicating with the individual chamber to supply the liquid to the individual chamber, and a discharge channel communicating with the individual chamber to discharge the liquid in the individual chamber. A fluid resistance of the supply channel is greater than a fluid resistance of the discharge channel.
Claims13
A liquid discharge head comprising:
- a nozzle to discharge a liquid in a nozzle discharge direction in which the liquid flows out of the nozzle;
- an individual chamber communicating with the nozzle;
- a supply channel communicating with the individual chamber to supply the liquid to the individual chamber;
- and
- a discharge channel communicating with the individual chamber to discharge the liquid in the individual chamber and extending downstream from the nozzle in a direction of flow of the liquid,
- a fluid resistance of the supply channel being greater than a fluid resistance of the discharge channel, and
- the supply channel and the discharge channel overlapping in a direction parallel to the nozzle discharge direction.
