IMPORTANT SAFETY NOTICES

1. Before disassembling or assembling parts of the scanner and peripherals, make sure that the scanner power cord is unplugged.

2. The wall outlet should be near the scanner and easily accessible.

3. The output voltage of the PSU (Power Supply Unit) can be either 100 ~ 120 Vac or 220 ~ 240 Vac, without any adjustment. Make sure that the above voltage is used.

4. The power cord should be an approved type, in accordance with the regulations for the country in which the scanner is used.

5. The use of cables other than the shield I/O cables or specified equivalents will invalidate the certification of this scanner and may cause interference levels which exceed the limits established for this equipment.

6. When keeping used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat buildup.

Lithium Batteries (Memory Back-up)

CAUTION The danger of explosion exists if a battery of this type is incorrectly replaced.

Replace only with the same or an equivalent type recommended by the manufacturer. Discard used batteries in accordance with the manufacturer’s instructions.

6.3.1 OVERVIEW

[A]

[C]

• The exposure lamp (a xenon lamp in this model) [A] illuminates the original. The image is reflected onto a CCD (charge coupled device) [B] via the 1st, 2nd, and 3rd mirrors, and through the lenses [C].

• The scanner scans the white plate [A] on the underside of the ADF exposure cover to perform the shading function.

• The scanners stop when the first scanner activates the home position sensor [E].

• If the scanner home position sensor is not activated within a certain time, a home

position sensor error will occur.

6.3.3 IMAGE PROCESSING

• The CCD generates three analog video signals.

• The SBU (Sensor Board Unit) converts these analog signals to 12-bit digital

signals.

• It sends these digital signals to the SCU (Scanner Control Unit) board through the VIOB board.

SCANNING 28 December, 2000

SBU and VIOB

The CCD converts the light reflected f rom the o rigin al into an analog signal. The CCD has an odd and an even output line for each of the three colors. Each

color also has an analog processing IC. The analog processing IC performs the following operations.

1. Z/C (Zero Clamp)

Adjusts the black level reference for even pixels to match the odd pixels.

2. Signal Amplification

Operational amplifiers in the AGC (Auto Gain Control) circuit amplify the analog signal. The CPU on the SCU board controls the maximum gain.

After the above processes, the analog signals are converted to 12-bit digital signals by the A/D converters. Each pixel is given a value from the 256-grade scale. The shading function then corrects those signals. Shading correction prevents uneven images caused by fluctuations in scanned data due to changes in light intensity and CCD sensitivity.

RIPU on SCU

The RIPU is the image processor on the SCU. It handles the following:

1. Line skipping correction

2. Scan line correction

3. Black and white conversion

4. Gamma (γ) correction

5. Color resolution

6. Filtering

7. Magnification

8. Scale processing

9. Erasure of Irregular Dots

Line skipping correction

Ideally, this machine would scan at a constant speed. However, when the data transfer speed slows down, the 1st scanner must also slow down to match. If the 1st scanner must stop to wait on the client or server, duplicate lines may be scanned. These can create a visible seam between the scanned sections. Line skipping correction erases duplicate image lines, ensuring a smooth final image.

6-6

Page 49

28 December, 2000 SCANNING

Scan line correction

The CCD consists of three lines of elements, one for each color (red, green and blue). Since there is a slight gap between the lines, each line is scanning a slightly different part of the image. To produce the final image, these three outputs need to be synchronized. Since the deviation between the lines varies with the scanner speed, a deviance value must be calculated in proportion to the speed.

Black and white conversion

When the machine scans a color original in the black and white mode, the RGB information needs to be converted into a grayscale image. Black and white conversion provides four different methods.

1. RGB data: All three colors are combined into the grayscale.

2. R data mode: Only the data from the red CCDs are used. This 256-grade data

is used directly as a 256-grade grayscale. Since green and blue data is not collected, those colors appear black in the final image.

3. G data mode: As R data but only using green.

4. B data mode: As R data but only using blue.

Gamma (

) correction

γγγγ

There should be a linear relationship between the original image density and the CCD output.

Gamma correction adjusts for deviations from this ideal. It includes both brightness and contrast corrections.

Color resolution

Because of the differences in color space, the color observed by a person, and the color value sensed by the CCD can vary. Color resolution corrects the color data gathered by the CCD. It uses a color table that adjusts for the way particular colors are displayed on specific CRTs. This allows a more-natural representation of the scanned image.

Filtering

There are two software filters: the MTF (Modulation Transfer Function) filter and the smoothing filter. The MTF filter emphasizes sharpness, and is used with documents that contain both text and photo areas. The smoothing filter is only used for photo-image documents.

SCANNING 28 December, 2000

Magnification

The RIPU enlarges or reduces the image data in the scan direction. Reduction and enlargement in the sub scan direction are done by changing the

scanning speed, using LIFO (last in, first out).

Scale processing

This process generates image densities of up to 256 levels for each pixel. It uses simple binary, dithering, and error diffusion processing.

Simple binary processing sets the level based on a threshold value. There are no shades of gray. The output is black or white only.

Dither processing is used to reproduce originals with continuous tones, such as photographs on machines that cannot output true grayscales. It produces different shades of gray by creating patterns of black and white dots. There are no gray dots.

The error diffusion process reduces the difference in contrast between light and dark areas of a halftone im age. Each pixel is corrected using the difference between it and the surrounding pixels. The corrected pixels are then compared with a matrix table. Error diffusion is often used in text/photo mode. It is a good compromise because it reduces the contrast between light and dark areas of halftone images, while having no effect on letter areas.

Erasure of Irregular Dots

When the CCD output is converted to a simple b i nary image, slight variations (noise) may result in individual pixels being incorrectly classified as either black or white. This process compares each pixel with its neighbors, using a matching technique to identify and remove these irregular dots.

OIPUB

The OIPUB is an optional image-processing unit. It improves the processing of black and white images using the following features:

1. Auto binary processing

2. Auto Image area separation

3. Manual Image area separation

Auto binary processing

When making simple binary scans of a light original (e.g. gray text on a white background), the threshold level is adjusted. This allows the lighter shades to appear in the final image (in the above example, as black text on a white background).

6-8

Page 51

28 December, 2000 NEWORK INTERFACE

Auto image area separation

When a sca nned document contains both text and photo areas, the machine searches for the outlines of the text. Based on these outlines, it separates the image into text and photo areas. Text areas use simple binary processing. Photo areas use dithering and error diffusion.

Manual image area separation

Here, the user separates the text and photo areas by hand (Use the TWAIN software). Image processing is the same as in auto image area separation.

6.4 NEWORK INTERFACE

The following network scanning options are available:

1. Network Transmission scanning

This scanner transmits the scanning image data to the scanner server. The scanner server then transmits the data to a client PC.

2. Network TWAIN scanning

The client PC sends scanning commands directly to the scanner. The scanner then sends the scanning image data back to the client PC.

IEEE1394 INTERFACE 28 December, 2000

6.5 IEEE1394 INTERFACE

6.5.1 IEEE1394

IEEE1394, also known as FireWire (a name patented by Apple), is an easy-to-use peer-to-peer networking technology, allowing speeds of up to 400 Mbps.

The current standard contains the following features, which are supported in most devices:

• Hot swapping (cables can be connected and disconnected while the computer and other devices are switched on)

• Peer-to-peer networking (no hub required)

• No terminator or device ID is required, unlike SCSI

• Automatic configuration of devices upon start-up (plug and play).

• Real-time data transfer at 100, 200, and 400 Mbps

• Common connectors for different devices

1394 I/F

G056D513.WMF

The cable length is limited to 4.5 m (15ft). However, up to 16 cables and 63 devices can be connected to an IEEE1394 network.

IEEE1394 cables can be either 4-pin (data only) or 6-pin (data and power). However, this machine only uses the 6-pin connectors. The machine has two 6-pin ports.

indicates the presence of the terminal plate in a given position. “Original Width-1” and “Original Width-2” are the outputs from the sensor board to the ARDF Interface board. The state of these outputs (L or H) depends on the position of the terminal plate on the sensor board (P1, P2, P3, or P4). For example, if the terminal plate is at P4, both outputs are L.

2) A reading of “L” on either of the width sensor outputs indicates that the terminal plate is connecting the GND pattern with the width sensor output signal line.
