Patent number: 9132676Abstract: In one example, a printhead assembly datum includes stationary first and second points and a movable third point that define a datum plane for the printhead assembly. The stationary first and second points define a line in the datum plane and the third point is movable so that the datum plane pivots on the line in response to movement of the third point. In another example, a printhead assembly includes a body, a printhead attached to the body, and a datum for adjusting a position of the printhead relative to a component external to the printhead assembly. The datum is formed by first, second, and third datum points on the body that define a triangle representing a datum plane that is tiltable on the base of the triangle by moving the vertex opposite the base.Type: GrantFiled: January 27, 2012Date of Patent: September 15, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Rosanna L. Bigford, Kelly B. Smith, Daniel D. Dowell
