Abstract
Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using at least one temperature dependent element disposed along an ink flow path. The temperature dependent element is configured to change shape responsive to a change in ink temperature. The change in shape causes a volumetric change in a portion of the ink flow channel.
