Cleaning the Components

This section explains how to clean the target mask, the white calibration cap, and the
inside of the integrating sphere.
Target mask
• If the glass portion of the target mask becomes dirty, gently wipe the dirt off using a soft
cloth. If the dirt does not come off easily, wipe using a cloth soaked in commercial lens
cleaner, and then wipe using a cloth soaked in water before drying.
• If areas other than the glass become dirty, gently wipe the dirt off using a cloth soaked
in water or soapy water. Never use solvents such as thinner or benzene.
• If the inside becomes dirty, blow off the dirt or dust using a blower.
Notes Do not touch the inside of the target mask or use a cloth to wipe off dust or
dirt on the mask. If the target mask is dirty, and the dirt cannot be removed
by a blower or the like, contact a KONICA MINOLTA-authorized service
facility.
White Calibration Cap
• If the white calibration area becomes dirty, gently wipe the dirt off using a soft cloth. If
the dirt does not come off easily, wipe using a cloth soaked in commercial lens cleaner,
and then wipe using a cloth soaked in water before drying.
• If areas other than the white calibration area become dirty, gently wipe the dirt off using
a cloth soaked in water or soapy water. Never use solvents such as thinner or benzene.
Notes Take care so as not to scratch the white calibration area.
