Abstract
A capping system has a cap for capping an ink jet print head, and a supporting structure for mechanically engaging and disengaging the cap with the ink jet print head. The cap has a vent. When the supporting structure engages the cap with the ink jet print head, the cap covers the ink jet print head to cap the ink jet print head. The vent in the cap ensures that the pressure inside the volume of the cap equalizes with the pressure outside the volume of the cap. This prevents overpressure within the cap.
