Patent number: 10974513Abstract: An example of an ink supply includes an ink chamber containing a liquid ink, a salt chamber containing a salt solution, a separator positioned between the liquid ink and the salt solution, and a release mechanism. The separator completely separates the liquid ink from the salt solution prior to the release mechanism being triggered. The release mechanism has a triggered position and a retracted position. The triggered position causes the separator to at least partially open, and enables the liquid ink and the salt solution to be combined to form a mixture.Type: GrantFiled: July 6, 2017Date of Patent: April 13, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jayprakash C. Bhatt, Larrie A. Deardurff, Milton Neill Jackson
