• The original size detection mechanism consists of an actuator and two original
width sensors.
• The actuator activates the original width sensor 1 and 2.
• Based on the combined output of the two width sensors, the machine can
calculate the size of the original.
NOTE: Since there are only two original width sensors, this mechanism can
detect only 4 original sizes. This is because each sensor detects “L” or
“H”. Therefore, the combination of sensor 1 signal and sensor 2 signal
is “L&L, L&H, H&L and H&H”. Because of this, some original sizes are
not detected correctly. Refer to the original size detection table.

• The CCD generates four analog video signals.

• The VBU (Video Board Unit) converts these analog signals to 10-bit digital
signals and performs the shading correction function.
• 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 and
the SCSI controller or USB controller.

B417/B418 6-18 SM
 ADF OVERVIEW

Scanner optics unit and VBU/ VIOB

The CCD converts the light reflected from the original into an analog signal.
The CCD has a single output line for each of the three colors, an odd and an even
line for black and white.
Each color also has an analog processing IC on the VBU. The analog processing
IC performs the following operations.
1. Z/C (Zero Clamp)
Adjusts the black level reference.
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 10-bit digital signals
by the A/D converters. Each pixel is given a value from the 256-grade scale.
The VIOB performs the shading function and then corrects these 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
Descriptions
Detailed
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 scanner must also slow down to match. If the
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.

SM 6-19 B417/B418
ADF OVERVIEW

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 (γ) correction

There should be a linear relationship between the original image density and the
CCD output.
Gamma correction adjusts for deviations. 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.

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).

B417/B418 6-20 SM
 ADF OVERVIEW

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 image. 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 binary 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

Descriptions
2. Auto Image area separation Detailed
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).

Auto image area separation

When a scanned 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.

SM 6-21 B417/B418

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.

DETAILED DESCRIPTIONS

5.2 OVERVIEW
5.2.1 GENERAL FEATURES
z This is an inkjet-type endorser.
z The endorser does not use any motors or solenoids.
z The ink ejection timing is adjusted automatically depending on the paper
transport speed.
z The machine can start printing the image after it completely scans the original,
or while it is scanning the original.

5.2.2 INK CARTRIDGE HEAD

This machine does not have a mechanism that automatically cleans the ink head.
Therefore, if low image density streaks appear in text areas, clean the ink head
with a damp cloth.

5.2.3 INK CARTRIDGE SENSOR

The shutter prevents ink from leaking out of the ink cartridge box. When the shutter
is closed, the endorser cannot print. The endorser uses a sensor (the ink cartridge
sensor) to detect the original.

5.2.4 ENDORSER OPERATIONS

1. The operator enables the endorser function from the scanner driver, and then
selects:
1) the characters they want to print and
2) printing on the leading edge or trailing edge.
The characters are printed on the rear side of the original.
2. The endorser supports 95 different characters. Operators can select a
maximum of 40 of these characters per job. (See next page).
3. The endorser can only be used with ADF Mode scanning.
4. The ink cartridge sensor detects the leading edge of the original when the
original passes the ink cartridge box. Based on this, the machine fixes the
printing start position for the sub-scan direction.
5. From the printer driver, it is possible to adjust the printing start position for the
sub-scan direction.
6. The endorser is installed under the ADF original tray.
7. The operator can change the printing position along the main-scan direction. To
do this, the operator slides the ink cartridge box to the left or right (see photo on
next page).
