1. INTRODUCTION
General Notes for Servicing General Description
The manual describes areas to be maintained, the detailed installation, the disassembly, and the component replacement procedures as well as the main trouble shooting guides.
Please take your time to read this manual thoroughly to obtain comprehensive knowledge about the scanner before serving the unit.
1.1 General notes for servicing
(1) Before trying to disassemble the scanner, make sure the power supply cord of the
scanner is disconnected from the power outlet. Under any circumstance, do not remove or install the connectors on the scanner with the power supply turned ON.
(2) Use caution not to drop small parts or screws inside the unit when disassembling and
reassembling. If left inside, they might cause the malfunction of the unit.
(3) Do not pull the connector cable when disconnecting it. Hold the connector. (4) When carrying the scanning head unit, put it in an anti-static bag. (5) Keep the document table glass surface always clean. If contaminated, use a dry
clean cloth for cleaning.
(6) Use caution not to injure your fingers or hands when disassembling or reassembling
the unit.

3. PRECAUTIONS OF
INSTALLATION/TRANSPORTATION
Precautions of Installation Transportation
3.1 Precautions of Installation
Pay attention to the following matters before unpacking and installation.
Do not install in a place where vibration may occur. Keep the scanner out of direct sunlight. Do not install near a heat source. Do not place the scanner around materials which shut off the circulation of air. Do not install in a humid or dusty place. Use care not to scratch the glass surface of the scanner or the document holding
pad with a clip or staple.
Do not use the wall socket with connecting devices which may generate noise, for
example, air-conditioner, etc.
Use a suitable AC power source. Place the scanner on a level surface.
3.2 Transportation
To move the scanner from where it is installed, for repair or any other reason, make sure to observe the following conditions:
(1) Turn off the power of the scanner. (2) Remove the power cable and lock the scanner. (3) Put the scanner in the packing case with the packing material.

Introduction Main Control Unit
4.1 Introduction
Figure 4.1 Theory of formation of image.
Service Manual
4-2
The reflected rays of your original as shown in the above figure pass through the lens and create an image on the CCD (Charged Coupled Device). Then, according to the different light intensity perceived by the CCD, the CCD will transfer these data into a series of analog signals to the main board, where the signals are turned into digital signals. The digital signals flow to the image processor and store into the CPU (Central Processing Unit). Through the commands from the Panel, the digital signals may goes to 4939 Controller to RJ-45 to the SMTP or filing server to send an email or store an image via entherne , or to remote printer to make digital copy via enthernet, as well as allow to usb flash drive or CF card ( removable storage) through usb host.
