Zusammenfassung:	Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using a membrane disposed along an ink flow path. The membrane includes first and second component membranes having first and second coefficients of thermal expansion. The membrane is configured to, in response to a change in ink temperature, mechanically displace as a function of temperature due to a difference in the thermal coefficients of expansion of the first and second component membranes. The mechanical displacement of the membrane causes a volumetric change in a portion of the ink flow path.
