1. Auxiliary Reflector : Reflects light onto the areas that Exposure Lamp LA1
cannot illuminate when an original does not lie flat on
the Original Glass (such as a book). It functions to
reduce shadows which would otherwise be transferred
to the copy.
2. Aperture Plates: : Regulate the amount of LA1 light illuminating the
original surface. (There are four plates.)
3. Exposure Lamp
Thermal Fuse TF1
: Becomes electrically open (blows) if the temperature in
the area surrounding the Main Reflector runs
excessively high, thereby preventing LA1 from being
kept ON or turning ON with the maximum line voltage.
4. Main Reflector : Ensures that light from LA1 exposes all areas of the
original.
5. Exposure Lamp LA1 : A halogen frost lamp is used and its light distribution
characteristics keep the intensity of the light remaining
flat.
6. Intensity Correction
Mirror
: Fitted on the front and rear ends of the Scanner, these
mirrors correct the intensity of the light emitted by LA1
slightly attenuated at the very ends.
