An ink supply unit for supplying a printhead containing an array of ink ejection nozzles, the supply unit including a first member formed having dimensions refined to a first accuracy and having a first cavity defined therein, a second member in the form of an ink distribution manifold having a second cavity defined therein, the second cavity being adapted for the insertion of a printhead, the second member being configured to engage the first cavity in the first member so as to define one or more chambers for the supply of ink to ink supply passages formed in the printhead, the second member being formed having dimensions refined to a second accuracy which is higher than the first accuracy. Preferably, the printhead is in the form of a printhead chip configured for use in a pagewidth inkjet printer. In the preferred form the second member defines a series of discrete ink outlets configured to deliver ink to ink supply passages provided in the printhead that are adapted to provide ink to grouped sets of ink ejection nozzles.
