Figure 5-4 The ink-jet array nozzle arrangement and cross-section

The printhead can be tilted backwards to provide for printhead maintenance,
printhead protection during transport, and for thermal isolation. The printhead,
in its home position, engages the tilt arm. At the lower end of the arm is a
cam-following bearing. The bearing rides in a cam-shaped groove in the head
tilt cam gear. As the gear rotates, the arm follows the motion and tilts back the
printhead. The printhead tilts back on the X-axis shaft that it travels on.
