Step 8: If the two spots are not superposition, adjust the screws on the back of the 2# mirror to make the
laser fire on the same position as the first spot.
Step 9: Repeat the sixth to eighth steps until the two spots overlap completely. Moreover, the spots should
be in the center of the hole.
Step 10: Affix multi-story double sticky tape paper on the 3# reflector, press pulse, get a spot on the paper.
If it is in the center of light hole, then pass.
Step 11: If the laser light is not in the center of light hole, as below figure:
In the left Figure, the spot is upper and right biased. Top to bottom bias: can only raise or lower the laser
tube. Inside and outside bias: only move the laser tube in or out to adjust. In this case, it is essential to
lower the laser tube (here refers to low-voltage side of the laser tube), and then, from the beginning of all
the re-adjustment of the first step.
