Abstract
An ink jet apparatus has a manifold and a feed tube of substantially the same cross-sectional areas as the manifold, thereby connecting the manifold with an ink reservoir so as to effectively present the large compliance characteristic of the reservoir at the manifold, and enabling a reduced volume print head construction which efficiently reduces cross talk and vibrational problems.
