III. SETTING UP THE SCANNER
A. Precautions
* Keep the scanner out of direct sunlight. Direct exposure to the sun or excessive heat may
cause damage to the scanner.
* Do not install the scanner in a humid or dusty environment.
* Use the supplied AC adapter only.
* Place the scanner securely on an even, flat surface. Tilted or uneven surface may cause a
mechanical problem.
* Keep the outer carton and packing material in case you may ship the scanner in the future.

I. BASIC OPERATION
A. Functions
The scanner functions are divided into the following three main systems.
1. Optical System
The optical system consists of the scanning lamp, lens and mirrors. It exposes a document,
then the reflected light from the document is collected onto a light-sensitive device CCD
(charge-coupled device ) via the lens and mirrors.
2. Image Processing System
The image processing system consists mainly of the CCD, analog IC, and ASIC. It converts
analog signals from the CCD into digital signals, which is read by the host computer.
3. Control System
The control system consists mainly of ASIC, USB controller, CPU, and motor driver. The CPU
controls the whole scanning operation. The USB controller controls the interface between the
CPU and ASIC, while the CPU interprets all commands from the host computer.
