Printhead with printhead module locator
View Patent ↗A printhead is provided for an inkjet printer. The printhead includes an elongate spine defining a channel and first location formations. An elongate ink distribution extrusion is receivable in the channel and defines spaced apart sets of ink supply holes. A printhead module locator defines second location formations which engage with said first location formations. A set of serially arranged ink ejection printhead modules is positioned adjacent the locator, and along the extrusion, so that the printhead modules engage with respective sets of ink supply holes.
1. A printhead for an inkjet printer, the printhead comprising:
an elongate spine defining a channel and first location formations;
an elongate ink distribution extrusion receivable in the channel and defining spaced apart sets of ink supply holes;
a printhead module locator defining second location formations engaged with said first location formations; and
a set of serially arranged ink ejection printhead modules positioned adjacent the locator and along the extrusion so that the printhead modules engage with respective sets of ink supply holes, wherein
the spine is a metal member having a flat base from which a pair of walls extend on either side, and
the first location formations are a pair of apertures defined in respective walls.
2. A printhead as claimed in claim 1 , wherein the second location formations include a pair of arms for snap fitting to respective apertures.
3. A printhead as claimed in claim 1 , wherein the sets of ink supply holes are parallel and oriented obliquely relative to the ink distribution extrusion.
4. A printhead as claimed in claim 1 , wherein the printhead module locator is shaped to receive the ink distribution extrusion.
5. A printhead as claimed in claim 1 , in which an end cap is engaged with the extrusion, the end cap including a pair of foldable tabs which can be snap fitted together around the extrusion.
