Figure 5-7 X-Axis Printhead Movement During Printing - Tektronix Phaser 360 Service Manual

X-axis or lateral movement of the printhead is accomplished by a short-pull
pulley system. Through a stiff, yet flexible band, the x-axis motor pushes on the
end of a lever arm which, in turn, pulls the x-axis shaft. The printhead, mounted
to the x-axis shaft, slews laterally across the surface of the drum. An x-axis home
sensor indicates when the printhead has been returned to the home position.
