Abstract
A method and apparatus for positioning a fluid ejection device such as an inkjet pen, or a plurality of aligned fluid ejection devices, on a supporting frame known as a printbar for page wide array printing involves provision of datum surfaces on each ejection device in two orthogonally related planes. First datum surfaces on the bottom of the devices support the device in a Z direction and second datum surfaces on opposite generally vertically extending sides of the fluid ejection devices are provided near the remote ends of the devices outwardly of electrical interconnects on each side of the devices. The device interconnects resiliently electrical interconnects mounted on the frame causing rotation of the devices to position the second datum surfaces on the device against positioning surfaces of the printbar to hold each fluid ejection device in correct position.
