ABSTRACT:
An ink jet pen includes an ink reservoir for containing ink and a catchbasin coupled to the reservoir by an orifice for containing ink displaced from the reservoir by environmental conditions. Also coupling the reservoir and catchbasin is an ink return mechanism that permits substantially all of the ink that may be displaced to the catchbasin to be returned to the reservoir regardless of the pen's orientation.
