Temperature dependent shape elements for void control in ink jet printers

摘要

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.

主权项

1. A subassembly for an inkjet printer for phase change ink comprising an ink flow path that includes at least one temperature dependent element configured to change shape responsive to a change in ink temperature, wherein the change in ink temperature that causes the shape change occurs when the ink temperature reaches a predetermined temperature or temperature range during a time that the ink transitions between liquid phase and solid phase, the change in shape causing a volumetric change in a portion of the ink flow path.
