Abstract
An inkjet printhead includes: an elongate support having a printhead mounting surface; a plurality of butting printhead chips mounted on the printhead mounting surface, each printhead chip having an ink ejection surface including one or more nozzle rows; and a grout material disposed between butting edges of each butting pair of printhead chips. Each printhead chip has a grouting trench defined in the ink ejection surface, the grouting trench extending alongside at least one butting edge and the grouting trench being disposed between an endmost nozzle of each nozzle row and the butting edge.
Claims20
An inkjet printhead comprising:
- an elongate support having a printhead mounting surface;
- a plurality of butting printhead chips mounted on the printhead mounting surface, each printhead chip having an ink ejection surface including one or more nozzle rows;
- and
- a grout material disposed between butting edges of each butting pair of printhead chips,
- wherein each printhead chip has a grouting trench defined in the ink ejection surface, the grouting trench extending alongside at least one butting edge and the grouting trench being disposed between an endmost nozzle of each nozzle row and the butting edge.
An inkjet printhead chip comprising a substrate having an ink ejection surface including one or more nozzle rows and a grouting trench defined in the ink ejection surface, wherein the grouting trench extends alongside at least one end edge of the substrate and the grouting trench is disposed between an endmost nozzle of each nozzle row and the end edge.
A method of fabricating an inkjet printhead, said method comprising the steps of:
- mounting a plurality of printhead chips in a butting arrangement on a printhead mounting surface of an elongate support, each printhead chip having an ink ejection surface including one or more nozzle rows and a grouting trench defined therein, wherein the grouting trench extends alongside at least one butting edge of the printhead chip and the grouting trench is disposed between an endmost nozzle of each nozzle row and the butting edge;
- flowing a grout material into a space defined between the butting edges of the printhead chips;
- pinning an advancing liquid front of the grout material at an edge of a grouting trench defined in the ink ejection surface;
- and
- curing the grout material.
