摘要： An inkjet printhead includes: a fluid manifold having a base defining a plurality of fluid outlets and printhead chips attached to the base. Each printhead chip receives printing fluid from a set of the fluid outlets. All fluid outlets are flared with a respect to a width dimension of the printhead chips for facilitating removal of air bubbles.

摘要： An inkjet printing system includes: (a) an inkjet printhead having a rigid elongate manifold with first and second parallel ink supply channels extending along a length of the manifold between respective ink ports positioned at opposite ends thereof; and a plurality of printhead chips mounted to a lower surface of the manifold, the ink supply channels supplying ink to the printhead chips via ink outlets defined in the lower surface. One end of the manifold has a first ink inlet port for the first ink supply channel and an ink outlet port for the second ink supply channel. The other end of the manifold has a first ink outlet port for the first ink supply channel and a second ink inlet port for the second ink supply channel. An ink delivery system is configured to flow ink along the first and second channels in opposite directions.

摘要： A method of inkjet printing includes the steps of: (i) delivering ink to a printhead manifold having a longitudinal ink channel, one or printhead chips mounted to a floor of the printhead manifold and in fluid communication with the longitudinal ink channel, and a plurality of sealed air cavities positioned over the longitudinal ink channel for dampening pressure fluctuations in the ink; (ii) printing from the printhead chips; and (iii) replenishing the air cavities with air.
