Put the test paper (paper self-adhesive tape) in front of the first reflecting mirror, then
press “TEST ”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.
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 in software to move the track to the
top left corner, press "TEST" key and check the location of the spot. Then move the track
to the lower left corner，press "TEST" 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).
The fourth step: Optical path adjustment between the second and the third reflecting
mirror.
First, move the laser head to the left of the X axis, put the test paper in front of the hole
