Pressure-based Ink level sense enhancement using a pressure controlling element in an Ink bag

摘要

An ink container (1102) that includes a collapsible ink reservoir (114) containing an ink supply, and a collapse controlling (115a-115e) insert disposed in the collapsible ink reservoir for controlling a remaining ink supply versus ink supply pressure characteristic of the collapsible ink reservoir. Also disclosed is an ink level detection system that includes a pressure transducer (71) for sensing a pressure of the ink supply that is indicative of remaining ink. <IMAGE>
