3. Tilt the front cover enough to enable you to apply the lens cleaning solution directly to the #3 mirror
and to the focus lens.
4. Flood the reflective surface of the #3 mirror with the solution. If heavy debris is present, let the
solution soak in for a minute.
5. Roll a fresh cotton swab across the mirror in one direction. Use a fresh swab for each pass. Be gentle
when cleaning the optic to avoid scratching the surface. Repeat this procedure for the focus lens,
but make sure you clean both sides of the lens.
Beam Window of Collimator
The beam window or collimator is where the laser beam enters into the processing area. It is located in the
upper left-hand corner of the engraving area against the back wall and is yellow in color. It is only necessary
to clean the front side of the beam window. Do not remove the optic to clean it; simply clean it in the same
manner as the #2 mirror.
Note: If your system is equipped with Gas Assist,
you must remove the optics protection housing to
gain access to the optic to clean it. Rotate the
beam window cover counter-clockwise (2) and
then off at a 45-degree angle (3). If the beam
window cover is stuck, use a 1/16 Allen wrench to
slightly loosen the screw (1) and try again. Set the
cover off to the side and clean the optic, if
necessary. Reinstall the beam window cover
being careful not to scratch the optic.
