Abstract
An ink manifold for an inkjet printhead is provided, comprising a number of substantially parallel transverse channelsconnected by one or more connecting passages. The resistance to flow provided by the connecting passages is substantially greater than the resistance to flow along the length of a transverse channel. The ink manifold provided by the present invention ensures that the ink pressure and flow rate presented to the ejectors of the printhead is uniform along the entire length of the ejector array and, moreover, does so in a shallower manifold design than has previously been known.
