This document will show you how to check and align your Mercury LaserPro. The first thing to do is to
check the alignment. Briefly the logic is to have a perfectly straight beam path from Mirror 2
(Back top left) to mirror 3 (Left end of X axis). From mirror 3 to mirror 4 (the one in the lens carriage).
Mirror 0 is for the red beam. Mirror 1 only controls where the beam hits the lens. If mirror 1 is adjusted
incorrectly you may be hitting the air nozzle at the bottom of the lens assembly.
If beam adjustment is necessary it may be easier to remove the lid for better access to the optics and to
see what your doing.
The first step is to check your machines alignment. We will check it in 4 places P1, P2, P3, and P4.

To start place a piece of tan masking tape, transfer tape, or small white label to back of mirror 3’s housing.
(Cover the hole the laser beam enters to get to mirror 3)
Turn on the machine while holding down the Start and Pause key on the Control Panel.

After the unit initialize the Display will look like this.
Press the function Key and wait for the RAM test. It will take
only a couple of seconds.
Press the right arrow (2) until the display looks like this.
Press the Down Arrow (3) until the display looks like the one below.
Power should now read 5%

You are now ready to check your beam alignment.
Position the X axis in PI (figure 1) The X axis should be pushed all the way back.
Close the Lid
.
Pull the x axis arm toward you und look at the back. There should be a small brown/black burn mark.
If there is not repeat blue above until you burn a small spot. If you burn a big spot you will need
a new piece of tape and repeat again.
Press the ENTER key fo about a second. A small amount of smoke should be seen
Figure 2 shows a correct burn.

Position X axis to P2 (Bring it all the way forward)
Put a small pen mark to the side of this dot so you will know which
dot was fired first.
Repeat steps in to create second dot.
If the dots are on top of each other you are done with mirror 2.

If your dots look something like this you need to adjust mirror 2.
Please note your Red Dot will NOT line up with your burn marks.
Do not attempt to line Red Dot up it will NEVER be in the same
spot as the C02 beam

It would now be a good time to remove the lid. Remove the 8 phillips head screws that hold the
lid to the chasse. There are two on each side
These are the two back screws
Tools required Philips and Standard Screw driver
Offset ratchet standard screw driver. I bought mine at OSH Sears sells them as
well as most hardware stores,
Disconnect 3 wire clips 1 Black and Orange
2 Black and Red . (On older models the Black
and Red wires will be in the back right) The B&R
are the lids interlocks . The B&O is the Door Open
LED. You will need to locate and press the release
on these connectors and pull apart.
The Grey Ribbon cable going to the control
panel is snug. It pulls out by gripping the
connector, or cable at the connector, and
pulling down.

Position the machine so that you can access all 4 sides.
Tape the acrylic lid closed and remove entire lid.
Lean the lid against the right side of the machine so that the Ribbon Cable can be plugged back in.
It is keyed and can only be plugged in one way.
Make sure the lid is propped so it will not slide .
Place two of the lid screws as shown above in booth of the BLACK and wire connectors

To do beam alignment you will need to understand a few basics.
1. First closest position to the mirror (P1 or P3) burn mark will not move.
2. We move P2 to line up on top of P1’s burn, and P4 to line up with P3.
3. The mirrors are aligned by adjusting 2 of the three screws on the prism mount.
One screw moves the beam path up and down while the other is left and right.
5. You need alignment more accurate.as small of a burn mark as possible to make
Place a piece of tape on the back of mirror 3’s sheet metal cover covering up the round hole.
Do a test fire as described in .blue text on page 2
If your results are not similar to the above you will need to adjust mirror 2 so that only 1 burn mark
and the red dot are visible on the test tape..
4. The red beam will not line up with the burn marks.
However, we adjust the screws and watch the results by following
In other words if the P2 is .06” high and .03” left from P1’s burn, we will

You may find it easier to put a pen mark as far from the red beam as P2 is from P1

Once mirror 2 is adjusted we will now repeat all the steps to check and adjust P3 to P4. Do not forget
to remove tape from back of mirror 3. Place your tape over the lens carriage opening.
(The hole on left side of lens carriage.)
As before P3 burn position will not move. Your goal is to get the dot from P4’s firing to line up on top
of P3’s. The difference here is P4 is so far away the beam gets quite large. The burn mark will take
longer to form and the dot is much larger. Burn in P4 1st to make visibility easier. Adjust the prism
mount of mirror 3 using the offset screw driver. Follow the same process as used on mirror 2.
Repeat until P3 falls on top of P4.
You are almost done.
Once you have adjusted the prism mount run the P2 burn again. If it lands on top of your original
P1 burn your done. If not re-adjust to correct. You may wish to use a new piece of tape and run P1
and P2 again. Repeat as often as necessary until P2 line up directly on top of P1

Lock Screws must be tightened when adjustments completed. Adjustments should
be made with lock screws snug, they may need to be loosened slightly if adjustment
is made on screws 1 or 2 in a clockwise direction. (Please note tightening up Lock
Screws may affect beam alignment adjust alignment as necessary)

Remove the lens form the lens holder. Place a piece of tape on the bottom of the air nozzle.
Rub it to leave an impression of the opening.
Make sure you remove the tape from the side of the carriage and fire for 1-2 seconds.
Remove the tape from the bottom of the air nozzle. The burn mark should be near the center
of the impression of the air nozzle opening.
If it is close to the edge you may be hitting the air nozzle and not getting full power. You will need to
adjust mirror 1 to move the beam away from the edge. Once completed re-check P1-P4 once more.
Any adjustments at this point should be quite minor.
To adjust mirror 1 you need to open up the back and left side to adjust Mirror 1, and Mirror
0. Mirror 0 is to position the red dot only. Mirror 1 only determines that the beam hits the center of the
lens.

Remove the 4 screws as shown below in figure 5 and open as in figure 6.

Next remove the small vent plate on the left side, bottom, of the machine (Figure 7) and remove
the two thumb screws and the black mirror cover (figure 8).

Adjust screws 1 and 3 only on any prism mount. One will be front to rear, while the other will be
left and right. Mirror 1’s prim mount is displayed below.

Last but not least follow the direction on how to reset origin.
How to set Origin
1.Turn unit On while holding down two Red Control Panel Buttons.
2.The display will eventually say "Run Test Pattern" press the Right Arrow once.
3.The display will now say "Set Origin" press Enter
4. Press Auto Focus
5. Press the Arrow keys to position the Red Diode beam in the corner of the rulers as
accurately as you can. Write down the Xand Yvalues displayed on the control
panel display on a piece of paper.
6. Press Enter
7. Turn Off Laser wait 10 seconds and turn it back on.
8. Set up a job with a small vector rectangle so that the top left corner is .5" from left,
and .5" from top. Run the job.
9. Measure your results. The left and top edge of the rectangle should be .5" from the
material edge.
10. If not repeat step 1-9. However this time rather the watching the Red Diode add or
subtract your actual error in location from the Xand, or Yvalues from Step 5.
Press the Arrows to move it to display the corrected numeric Xand Ylocation.
11. Repeat until you have the desired origin set. Keep the correct numbers written
down below for future need. If Origin needs to be set again in the future you can
use these numbers rather than using the Red Diode method as above.

To align the Red Beam adjust the prism mount for mirror 0 so that the red dot hits the burn mark
on the tape on the bottom of the air assist nozzle from your final test of mirror 1’s adjustment.
