• The exposure lamp (a xenon lamp in this model) [A] illuminates the original. Theimage is reflected onto a CCD (charge coupled device) [B] via the 1st, 2nd, and3rd mirrors, and through the lenses [C].

• The scanner scans the white plate [A] on the underside of the ADF exposurecover 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.• The RIPU (Image Processing Unit) IC on the SCU processes the image, and

then the image data is sent to the computer through the Memory Control IC andthe SCSI controller.

SBU and VIOB

The CCD converts the light reflected from the original into an analog signal.

The CCD has an odd and an even output line for each of the three colors. Eachcolor also has an analog processing IC. The analog processing IC performs thefollowing 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 analogsignal. The CPU on the SCU board controls the maximum gain.

After the above processes, the analog signals are converted to 12-bit digital signalsby the A/D converters. Each pixel is given a value from the 256-grade scale. Theshading function then corrects those signals. Shading correction prevents unevenimages caused by fluctuations in scanned data due to changes in light intensityand 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 datatransfer speed slows down, the 1st scanner must also slow down to match. If the1st scanner must stop to wait on the client or server, duplicate lines may bescanned. These can create a visible seam between the scanned sections. Lineskipping correction erases duplicate image lines, ensuring a smooth final image.


6-7

De

Scan line correction

The CCD consists of three lines of elements, one for each color (red, green andblue). Since there is a slight gap between the lines, each line is scanning a slightlydifferent part of the image. To produce the final image, these three outputs need tobe synchronized. Since the deviation between the lines varies with the scannerspeed, 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 RGBinformation needs to be converted into a grayscale image. Black and whiteconversion 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 datais used directly as a 256-grade grayscale. Since green and blue data is notcollected, 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 (γγγγ) correction

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

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

Color resolution

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

Filtering

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


6-8

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

Scale processing

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

Simple binary processing sets the level based on a threshold value. There are noshades of gray. The output is black or white only.

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

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

Erasure of Irregular DotsWhen the CCD output is converted to a simple binary image, slight variations(noise) may result in individual pixels being incorrectly classified as either black orwhite. This process compares each pixel with its neighbors, using a matchingtechnique to identify and remove these irregular dots.

OIPUB

The OIPUB is an optional image-processing unit. It improves the processing ofblack 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 whitebackground), the threshold level is adjusted. This allows the lighter shades toappear in the final image (in the above example, as black text on a whitebackground).

Auto image area separation

When a scanned document contains both text and photo areas, the machinesearches for the outlines of the text. Based on these outlines, it separates theimage into text and photo areas. Text areas use simple binary processing. Photoareas use dithering and error diffusion.

Manual image area separation

Here, the user separates the text and photo areas by hand (Use the TWAINsoftware). 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. Thescanner 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 thensends the scanning image data back to the client PC.

6.5 IEEE1394 INTERFACE

6.5.1 IEEE1394

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

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

• Hot swapping (cables can be connected and disconnected while thecomputer 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

The cable length is limited to 4.5 m (15ft). However, up to 16 cables and 63devices 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-pinports.

2.2.1 ORIGINAL SIZE DETECTION

• The original size detection mechanism consists of the original width sensor board[A] and two original length sensors--sensor-1 [B] and -2 [C].

• Based on the combined output of the length sensors and the width sensor board,the machine can calculate the size of the original.

NOTE: Since the width sensor’s terminal plate is attached to the original guide, allthe originals must be the same width.

NOTE: 1) P1-P4 represents the four positions on the width sensor board. ONindicates the presence of the terminal plate in a given position. “OriginalWidth-1” and “Original Width-2” are the outputs from the sensor board tothe ARDF Interface board. The state of these outputs (L or H) dependson the position of the terminal plate on the sensor board (P1, P2, P3, orP4). 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 theterminal plate is connecting the GND pattern with the width sensoroutput signal line.

2.3.3 ORIGINAL TRANSPORT AND EXIT

Single –sided originals

• The DF feed motor feeds the separated original to the first transport roller [A] atmaximum speed.

• When the registration sensor [B] detects the leading edge, the motor stopsbriefly.

• Then the feed and transport motors turn on again, and feed the original throughscanning area at a lower speed.

• The original is fed out by the second transport roller [E] and the exit roller [F].

Double-side originals

– Front side –

When the registration sensor [A] detectsthe leading edge of the original, the DFfeed motor and the transport motor bothswitch off. After a brief interval, thetransport motor alone reactivates to drivethe first and the second transport roller [B,C] and the exit roller [F].

– Rear Side –

When the original exit sensor [D] detectsthe leading edge of the original, thejunction gate solenoid is activated and thejunction gate [E] opens. To transport theoriginal towards the reverse table [F].

After the trailing edge of the originalpasses the exit sensor [D], the junctiongate solenoid switches off and the junctiongate [E] closes.

When the original has been fed completely onto the reverse table, the DF feedmotor switches on in reverse. The reverse roller [G], exit roller [F] and first transportroller [A] then feed the original back to the scanning area.

The original is then sent to the reverse table [H] a second time. This ensures thatthe duplex copies will be properly stacked front side down in the exit tray [I].
