Power distribution arrangement for an injet printhead
First Claim
1. A power distribution arrangement and inkjet printhead assembly comprising:
- a microelectromechanical elongate inkjet printhead of a kind having a plurality of longitudinally spaced discrete voltage supply points, signal connections and ink supply passages, said printhead mounted in a housing having a series of hydrophobically sealed holes for the ingress of air;
two or more elongate power supply busbars;
a flexible interconnect means folded about the housing, the flexible interconnect means including;
a plurality of connecting lines formed on a first surface thereof connecting a selected plurality of said voltage supply points to said busbars and a plurality of control line interconnects formed on a second surface thereof connected to the signal connections;
an elongate ink distribution manifold located within said housing having a number of ink outlets in communication with the microelectromechanical elongate inkjet printhead ink supply passages;
clamping means clamping said busbars to the housing;
an ink filter fitted about said ink distribution manifold; and
a baffle interposed between the ink distribution manifold and the housing, the baffle including at least one pierceable end wall portion for receiving an ink supply conduit.

Abstract
An ink supply unit for supplying separate color inks to a portable ink jet print head, the ink supply unit including: a slot for insertion of the printhead; a series of elongated chambers for the storage of the separate color inks, the chambers being interconnected with the slot for the supply of ink to the printhead; a series of conductive rails along the outside of the ink supply unit, each conductive rail interconnected to a power supply at a series of points along the conductive rail; a tape automated bonding strip along the outside of the ink supply unit having a series of control lines along one surface thereof for mating with a corresponding external series of control lines, the tape automated bonding strip further having a repeating series of interconnects to the printhead, the interconnects interconnecting the control lines and the conductive rails to the printhead. The unit can be detachable from the power supply and the external series of control lines.
