NOTE: For more severe PRINTER error messages which prevent printing altogether [i.e. “Replace
Printhead”, “Missing Printhead” or “Incompatible Printhead"] this is typical of failed micro-electronics
within the PRINTHEAD assembly (nothing to do with the HP 950/951 refilled ink cartridges). The
PRINTHEAD assembly is a separate electronic unit in which the cartridges plug into and feed ink to and is
essentially the heart of the printing system. For reference, please refer to our video on how the
PRINTHEAD works: http://inkjet411.com/?page_id=2054
