Beam alIgnment
1. Loosen 2 silver bolts that hold down the colour
alignment mechanism cover and remove the cover.
2. Power up the system as normal.
3. Firstly, it is necessary to align a colour with the longest
beam path between the laser module output and the
scanning system in a way so it hits the exact centre
of the bottom scanning mirror – in this case it is the
blue laser beam.
Create a blue beam effect (point) and check visually
whether the beam hits the exact centre of the bottom
scanning mirror. If not, follow the diagram below
to adjust the beam path accordingly (step 1 on the
diagram).
!
All alignment screws A,B,C and D must
be fastened at the end of each beam
alignment procedure. Even if only one
of them is loose, there will be not enough
internal pressure on the pivoting bolt
(E), which may result into misalignment
of respective colour.
4. Create a full size cyan circle (static tunnel effect) and
check whether the green circle overlays the blue circle
all the way around the shape. If not, adjust the beam
path of the green circle accordingly (step 2 on the
diagram above).
5. Create a full size yellow circle (static tunnel effect)
and check whether the red circle overlays the green
circle all the way around the shape. If not, adjust the
beam path of the red circle accordingly (step 3 on the
diagram above).
6. Create a full size red circle (static tunnel effect) and
check whether the 2nd red circle overlays the 1st red
circle all the way around the shape. If not, adjust the
beam path of the 2nd red circle accordingly (step 4
on the diagram above).
7. Finally create a full size white circle (static tunnel effect).
If the alignment procedure was done successfully you
can see all the colours nicely overlaying each other,
resulting in even, bright and sharp circle like the one
on the picture below.
!
Always loosen one of the screws in the
pair first, before tightening the 2nd one
down.
