Printhead with print artifact supressing cavity |
| 摘要 |
A printhead includes a nozzle plate including a plurality of nozzles and a manifold body bonded to the nozzle plate. The manifold body includes a liquid channel in fluid communication with the plurality of nozzles. A cavity that dampens pressure modulation in liquid channel of the manifold body is located between the nozzle plate and the manifold body. The cavity is fluidically common to the plurality of nozzles. |

1. A printhead comprising:
a nozzle plate including a plurality of nozzles; a manifold body bonded to the nozzle plate, the manifold body including a liquid channel in fluid communication with the plurality of nozzles, the liquid channel having a length; and a cavity located between the nozzle plate and the manifold body that dampens pressure modulation in liquid channel of the manifold body, the cavity extending along the ink channel, substantially along the length of the ink channel such that the cavity is fluidically common to the plurality of nozzles. |
