CLEANING THE MIRRORS
There are two mirrors inside the processing area of the system that need to be cleaned. Follow the
procedure below to clean both of mirrors:
1.
While holding the mirror bracket, remove the 4-40 thumb screw and lift mirror and holder
away from the mirror mount. Be careful not to slide the mirror across the mount since they
can scratch easily.
2.
Use a stream of lens cleaning solution from the small plastic wash bottle to flush the surface
of the mirror.

3.
Apply lens cleaning solution to the mirror and let it sit for approximately one minute.
4.
Use a folded piece of lens tissue soaked in lens cleaning solution and gently wipe it across
the mirror once. Use new lens tissue soaked in lens cleaning solution and repeat wiping with
each new tissue across the mirror once until the mirror is clean and then dry it with a dry
lens tissue. Never use a tissue twice as dust build-up on the tissue may scratch the mirror's
surface.
5.
Inspect the mirror and repeat the procedure if necessary until the mirror is clean.
6.
Replace the mirror on the mirror mount by setting the mirror bracket straight down on to the
mount. Make sure that the mirror is sitting flat against the holder otherwise a beam
misalignment can occur. Replace the 4-40 thumb screw and tighten it securely.
CAUTION: Sliding the mirror on the holder can scratch it.
