Abstract
A short tapered elastomer tube carries ink from a reservoir to an ink jet print head. The tube has a substantially constant inside diameter throughout the length thereof and a decreasing outside diameter along a portion of the length to provide a thin wall section for absorbing return pressure waves generated from the nozzle of the print head.
