Abstract
The present invention provides for an improvement in the removal of fluid from an ink jet printhead. A branched structure having multiple groups of branches creates a flow geometry, with each group of branches having a connecting trunk. The fluid flow is then able to be directed from each plurality of branches down the connecting trunk. Pressure drops at the branching nodes are minimized by directing the flow from the combined branches down the connected trunk. Expansion losses at the branching nodes are minimized by funneling down the flow at the branching nodes, with the trunk having a narrower channel than the combination of the joined branches.
