Figure 48 Steps to aligning laser on cantilever beam tip
4 Rotate the front-to-back knob counterclockwise until the spot just
reappears on the paper. The spot is now at the edge of the chip
(Diagram C in Figure 48).
5 Rotate the left-to-right knob to position the laser on the cantilever
(Diagram D in Figure 48). As the laser passes over the cantilever it
will disappear and reappear in rapid succession. You should now see
the laser spot on the scanner’s frosted glass.
6 Turn the front-to-back knob counterclockwise to move the spot
down the cantilever, toward the tip until the spot on the frosted glass
disappears (and the spot reappears on the paper) (Diagram E in
Figure 48).
7 Turn the front-to-back knob clockwise slightly to position the laser
just on the cantilever tip (Diagram F in Figure 48). The spot will
reappear on the ground glass.
