Abstract

A print head ink supply unit is disclosed for supplying a pagewidth print head for the ejection of ink by the print head having a first surface having a plurality of holes for the supply on ink to a series of ejection nozzles, the print head supply unit comprising a plurality of long columnar chambers for storing an ink supply, one for each output color, the chambers running substantially the length of the printhead adjacent the first surface thereof; and a series of tapered separators separating the chambers from one another, the tapered separators being tapered into an end strip running along the first surface along substantially the length of the printhead. The unit can further include a series of regularly spaced structural support members for supporting the tapered separators in a predetermined relationship to one another. The tapered separators can be formed in a single ejection molded unit with a wall of the unit abutting the printhead. The tapered separators taper to substantially abut a slot in the wall of the unit, the slot being adapted for the insertion of the print head.
