Printhead assembly with end-to-end printhead integrated circuit carriers
View Patent ↗A printhead assembly includes an elongate support structure. A series of side wall sections extend a length of the support structure and define ink supply channels. Edges of the walls delineate a gap. A plurality of carriers is positioned end-to-end in the gap and is supported by said edges of the walls. The carriers define a recess and ink supply passages in fluid communication with the recess and the ink supply channels. A printhead integrated circuit is mounted in each recess to receive ink from the ink supply channels.
1. A printhead assembly comprising:
an elongate support structure;
a series of side wall sections extending a length of the support structure and defining ink supply channels, edges of the walls delineating a gap;
a plurality of carriers positioned end-to-end in the gap and supported by said edges of the walls, the carriers defining a recess and ink supply passages in fluid communication with the recess and the ink supply channels; and
a printhead integrated circuit mounted in each recess to receive ink from the ink supply channels.
2. A printhead assembly as claimed in claim 1 , in which the elongate support structure is a profile member of semi-open cross-section, the profile member having a peripheral, structured wall of substantially uniform thickness, the side wall sections being positioned on a base wall section of the structured wall.
3. A printhead assembly as claimed in claim 2 , in which free edges of the profile member and the free edges of the side wall sections define points on a semi-circle, such that the profile member and side wall sections define a semi-circular slot.
