<p>The invention relates to a vent system for an ink jet pen (6) having an internal pressure regulator (98). The vent system (40) provides air flow communication between the exterior of the ink jet pen (6) and an interior chamber associated with the pressure regulator (98) while substantially inhibiting the flow of water vapor out of chamber to the exterior of the pen (6). The vent system (40) includes an elongate flow path defined adjacent the exterior of the pen (6), the flow path having a first end in flow communication with the chamber and a second end in flow communication with the exterior of the pen (6).</p> |
