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.
