Abstract
A phase change inkjet printer including a heated phase change ink reservoir configured to reduce or prevent improper jetting of ink from a printhead. The reservoir includes a vent to atmosphere to provide substantially consistent and accurate jetting of the heated ink. A selective barrier, such as a filter, disposed adjacent to the vent substantially prevents ink from entering the vent while still enabling the vent to direct a pressure into the reservoir during printing and during purging.
