Abstract
Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using one or more separator elements configured to separate bubbles of a vapor from ink. Each separator element includes wicking features having dimensions sufficient to allow capillary movement of the ink in the wicking features and to substantially exclude the bubbles from the wicking features. One or more inlets allow passage of the ink that includes the bubbles into the separator element. At least one vapor outlet allows vapor that has been separated from the ink to exit from the separator element. The ink exits from the separator element thought one or more ink outlets.
