Printhead assembly with power and ground connections along single edge

摘要

A printhead assembly with an elongate printhead and a plurality of power supply points and ground supply points spaced along its length. The assembly also has an elongate power busbar and an elongate ground busbar with an interconnect means 470 connecting said power supply points 553 to the power busbar and the ground supply points to said ground busbar; wherein, the interconnect means 470 attaches to the printhead along a single longitudinal edge 554 thereof. By attaching to one edge of the printhead IC only, the assembly design is less complex and more compact.
