ABSTRACT:
An ink reservoir having a body and a cover disposed on the body is provided. A vent is disposed in the cover. The vent has a vent hole passing through the cover and an elongated vent path that communicatively couples the vent hole to an atmosphere surrounding an exterior of the ink reservoir. An oleophobically treated, porous membrane is disposed over the vent hole for acting to repel ink therefrom and for allowing airflow through the porous membrane and the vent.
