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.

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.
