Abstract: 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.

Abstract: 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.

Abstract: A printing unit includes: a unit chassis for mounting over a media feed path; first and second elongate printheads mounted on the unit chassis and positioned in an overlapping arrangement across the media feed path; a first aerosol extractor positioned downstream of the first printhead relative to the media feed direction; and a second aerosol extractor positioned downstream of the second printhead and the first aerosol extractor relative to the media feed direction. The first and second aerosol extractors are positioned at a same distance from their respective first and second printheads.

Abstract: A printing unit includes: a base plate defining an elongate slot extending across a media feed path; an elongate printhead positioned in the slot for printing onto print media fed along the media feed path; an aerosol extractor positioned downstream of the printhead relative to a media feed direction, the aerosol extractor providing an airflow through a print zone associated with the printhead; and air guides projecting from a lower surface of the base plate towards the media feed path. The air guides are positioned at opposite ends of the printhead and include respective guide walls for directing the airflow towards the aerosol extractor.
