I. BASIC OPERATION
A. System Configuration
  The film adapter unit FAU-S11 is an optional device for CanoScan FB1210U to provide the
light source for scanning films.
  When the appropriate light source projects through a film and the host computer program
controls the scanning unit moving, charge-coupled-device (CCD) collects all the light signals of
the film and synchronically generates the real analog signals.  The main PCB then converts the
analog signal into digital signal.  Finally, scanner driver transforms the digital signal into an
image and saves it in the host computer.
