1. Read the visible light position. Two holes in the upper housing are
scanned with visible light in order to register the home position of
image being scanned.
2. Move the secondary lens (Glass Plate) into position and scan the
film in visible-light.
3. Retract the secondary lens and scan the film in infrared-light.
4. Electronically superimpose the images obtained from each light
source and identify the physical flaws and/or foreign matter.
5. Replace the "flaw" image data with image data interpolated from
adjacent areas.
