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 Figure:

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 ofthe hole of
the laser head, press "Pulse/Run" key slightly and check the spot. Then move the laser
head to the right of the X axis, press "Pulse/Run" again, and check whether the two spots
coincide with each other, if coincide and the two spots are within the hole of the laser
head, then optical path is correct. If not, please adjust the screws on the second mirror
holder to reach above standard（Attention：the principle of optical path adjustment is the
same between mirror 1 and 2, 2 and 3）. Then adjust the location of second mirror holder
