Clean and Replace Protective Glass
Each f -theta lens is equipped with an optically-coated protective glass. When marking materials over a
period of time, many of the airborne particles produced during the marking process can dirty or fog the
protective glass.
It is important to keep the protective glass clean. If the protective glass is dirty and
continually used, the contaminants may permanently damage the glass surface. When cleaning the
surface, use only lens cleaning paper. A scratched glass surface will cause undesirable marking results.
Required Items:
x
Lens Cleaning Paper
x
Acetone
x
Air Blower
x
Powder-free Vinyl Gloves or Finger Cots

NOTE: Before you clean the
protective glass, put on a pair of
powder-free vinyl gloves or finger cots.
3. Add a few drops of acetone onto the
lens and use the lens cleaning paper to
wipe the protective glass. When
cleaning,
draw a spiral pattern from
the center of the glass as shown .
NOTE: If you can not get the
protective glass clean after several
attempts, replace the protective glass
with a new unit.

the Marker by turning it in the CW
