2. DETAILED SECTION DESCRIPTIONS
2.1 SCANNING
2.1.1 OVERVIEW
The original is illuminated by the exposure lamp (a xenon lamp in this model) [A].
The image is reflected onto a CCD (charge coupled device) [B] via the 1st, 2nd, 3rd
mirrors, and lens [C].
The 1st scanner [D] consists of the exposure lamp, a reflector [E], and the 1st
mirror [F].
A lamp stabilizer energizes the exposure lamp. The light reflected by the reflector is
of almost equal intensity, to reduce shadows on pasted originals.
An optics anti-condensation heater [G] is available as an option. It can be installed
on the left side of the scanner. It turns on whenever the power cord is plugged in.
