CHAPTER 1

I. FEATURES

CanoScan FB330P (hereafter FB330P) with 300 x 600 dpi resolution, CanoScan FB630P (hereafter FB630P) and CanoScan FB630U/FB636U (hereafter FB630U/FB636U) with 600 x 1200 dpi resolution are flatbed image scanners incorporating the following features.

1. High gradation and high image quality are achieved by employing a highly sensitive contact

image sensor with LIDE (LED Indirect Exposure) technology for the reading unit, and by reading each RGB color by 12 bit and outputting by 8 bit.

2. The scanner is a small size of 256.0(W) x 372.5(D) x 39.0(H) mm, and a light weight of 1.5

kg by using a downsized scanning unit.

3. The scanner can easily be connected to the host computer through a parallel interface

(FB330P/FB630P) or a USB interface (FB630U/FB636U).

4. The scanner can be placed vertically to scan by using an optional stand.

5. CanoScan FB630U/FB636U draws its power from USB port on the host computer requiring

no AC adapter.

IV. INSTALLATION

A. Preface

The following installation conditions are required.

1. Ambient temperature should be between 5½C and 35½C, and humidity between 10% and 90%. Avoid locations near water faucets, boilers, humidifiers, or refrigerators.

2. Avoid locations subject to open flame, dust, or direct sunlight. If it is installed near a window, hang a curtain to block direct sunlight.

3. The room should be well ventilated.

4. Install on a sturdy and level desk, etc.

5. Moving a scanner from a cold place to a warm place can cause condensation on the metal parts, resulting in a faulty operation. Give the scanner at least one hour to adjust to the room temperature before unpacking.
