Processing options for the scanner handpieces
Disconnect the focusing handpiece from the articulated mirror arm (or the scanner handpiece
from the scanner), then disassemble the handpiece. The components 1 and 2 (Fig. 8.1 or 8.2)
can be cleaned by immersion in a disinfecting solution and subsequent sterilization (options:
steam sterilization at 134°C (273°F); ethylene oxide gas sterilization; formaldehyde gas
sterilization; plasma sterilization).
Please note that the optics of the focusing and scanner handpieces (component 3, Fig. 8.1 and
Fig. 8.2) may neither be immersion-treated nor steam-sterilized (however, gas or plasma
sterilization is permitted). As a general rule, this component needs cleaning only when its
surface has become visibly dirty. To clean a lens, lint-free wiping paper (e.g. lens cleaning
paper) in conjunction with acetone or pure alcohol must be used. Proceed as follows: Grasp
the optics, remove any dust or dirt from the lens surface using a blower, then put some
cleaning solution onto the lens surface. Fold the wiping paper several times, then use the
resulting edge or "lip" to remove the cleaning solution by wiping over the surface just once. Do
not rub the surface in a circular motion!
