ABSTRACT:
An inkjet printhead with ink chambers that are supplied with ink via an adjacent ink chamber. The conduits for distributing ink to every ink chamber in the array can occupy a significant proportion of the wafer area. By making some ink chambers part of the ink flow path to other ink chambers, while keeping each chamber sufficiently free of fluidic cross talk, reduces the amount of wafer area lost to ink supply conduits.
