Abstract
A print head reservoir for use in an ink jet printer includes a body, an ink bucket, and a filter. The body defines an ink cavity. The cavity includes a cavity inlet, a cavity outlet and a vent positioned above the cavity inlet for bleeding air from the ink cavity. The ink bucket attaches to the body. The ink bucket communicates with the cavity via the cavity inlet. The filter is disposed in the cavity dividing the cavity into an upstream filter cavity and a downstream filter cavity.
