The first step: Regulate test power to below 50%, to keep the power not too high.
The second step: Optical path adjustment between laser rube and the first reflecting Mirror. Put the
test paper (paper self-adhesive tape) in front of the first reflecting mirror, then press
“
Pulse/Run
”
button slightly(loose immediately after pressing slightly, only you can see the spot on the test paper),
then check whether there is a spot in the center of the first reflecting mirror. If in the center, you have
finished the first step. If there is no spot or the spot is not in the center, please adjust the location and
the height of the first reflecting mirror holder (or laser tube) to meet above standard. (Below Figure)

The third step: Optical path adjustment between the first and the second reflecting mirror.
First of all, put the test paper(paper self-adhesive tape) in front of the mirror of the second reflecting
mirror holder, using direction keys on the control panel to move the track to the top left corner, press
"Pulse/Run" key and check the location of the spot. Then move the track to the lower left corner
，
press
"Pulse/Run" key again, To check whether the two spots( the top left corner and the lower left corner)
coincide with each other. If the two spots coincide with each other and near to the center of the mirror,
it shows optical path between the first reflecting mirror and the second reflecting mirror is correct; if
not, please adjust the screws at the back of the first reflecting mirror holder to make sure the spots
coincide with each other. Then adjust the location of the first mirror holder (X-axis direction), to make
sure the light reflected by the first reflecting mirror hit on the second reflecting mirror(Center). Below
