B. Electrical System
1. Outline
Figure 2-2 is an electric system circuit diagram.
The scanner is not equipped with CPU. The device driver with a control program installed in
the host computer functions as CPU. The host computer sends a command to the ASIC via the
USB controller or IEEE 1394 controller. The ASIC controls the whole electrical circuits and
image processing of the scanner. The image signals read by the CCD are converted into digital
data by analog IC. The digital data is then processed by the ASIC and is output to the host
computer via USB interface.

CHAPTER 2
II. OPTICAL SYSTEM
A. Outline
The optical system consists of the scanning lamp, lens and mirrors. When scanning a
reflective materials such as papers , the original is exposed to the light of the scanning lamp in
the scanning unit. The reflected light of the original forms an image on the photosensitive
device, CCD (charge-coupled device) via lens and mirrors.
When scanning transparent material such as films, Light of the FAU lamp in the Film
Adapter Unit transmits the film. The transmitted light forms an image on CCD.
When scanning with FARE function, IR LED instead of FAU lamp works to operate FARE unit.

CHAPTER 2
B. Lamp Lighting Circuit
1. Scanning Lamp Lighting Circuit
When the scanner is turned on, or the host computer sends a scan command, ASIC turns on
the scanning lamp lighting signal (LAMP) to light the scanning lamp.
The reflected light of the original is focused on CCD (charge-coupled device) via the five
mirrors, lens and FARE unit.
The scanner is equipped with a lamp OFF function for energy saving. A built-in timer
automatically turns off the lamp if no scanning command is sent from the host computer for a
certain period of time. Setting up of the timer is conducted by the device driver.

CHAPTER 2
2. FAU Lamp Lighting Circuit
Figure 2-7 is a FAU Lamp Lighting Circuit diagram.
When the host computer sends a film scanning command, ASIC turns off the scanning lamp
lighting signal (LAMP) and simultaneously turns on FAU lamp lighting signal (XPA) to light the
FAU lamp.
Light of the FAU lamp is converted into a flat light source by a light guide plate. The light is
diffused by the1st diffusive film, the luminous intensity enhancement film and the 2nd
diffusive film. Light transmitted the transparent plate all has the same luminous intensity as a
result. Light transmits a film and is focused on the CCD in the scanning unit.
The FAU lamp also has a lamp OFF function for energy saving.
3. Infrared LED Lighting Circuit
When the host computer sends a command to light an IR LED, ASIC turns on IRLED signal to
light the IR LED.
The IR LED light is converted into a flat light source by a light guide plate. Light transmits a
film via the1st diffusive film, the luminous intensity enhancement film, the 2nd diffusive film
and the transparent plate.
