Step 3. Remove the residue mark.
Step 4. Let the focal lens dry before reattaching it to the marker.
Use acetone if the lens cleaner will not remove the mark. Be careful not to
scratch the lens. After the mark is removed, follow the steps used to clean
residue marks in order to finish the cleaning.
Oil from hands and the residue that builds up on the scan lenses can distort the
laser beam passing through, resulting in poor quality markings and may cause
cracks by the uneven heat conduction.
