The process is similar for triangular-shaped cantilevers, with the
exception that the laser will be obscured twice as it moves left to right
(over the two beams). The process is shown in Figure 49.

A potential error during the alignment process is to turn either of the
positioning controls too far in the wrong direction and to thereby lose
the laser spot altogether. Figure 50 shows the positioning controls when
they are well out of alignment. The left-to-right knob will be visibly
tilted when the lateral alignment is far out, and the laser housing will be
moved to one side when the front-to-back alignment is out. The easiest
way to recover is to roughly center both controls again, moving the laser
