4.3.2 Other Image Options
Binarization Thi
s is the process of converting a
grayscale or color image to a bi-tonal
image. There are several different
methods of performing this conversion.
Options: Dynamic Threshold,
Dynamic Threshold (AD), Fixed
Processing, Halftone 1~5, Error
Diffusion.
Dynamic Threshold: Selecting
Dynamic Threshold allows the scanner
to dynamically evaluate each document
to determine the optimal threshold value
to produce the highest quality image.
This is used to scan mixed document
containing faint text, shaded background,
or color background with a single setting.
If Dynamic Threshold is selected,
Threshold, Brightness, and Contrast are
not available.
Dynamic Threshold (AD): Selecting
Dynamic Threshold (AD) to perform
the enhanced mode of the Dynamic
Threshold feature. However, using this
mode may slow down your scanning
speed.
Sensitivity of Dynamic Threshold
Occasionally your scanned image may
contain small dots or speckles. To remove
these spots, increase the sensitivity value
by moving the bar to the right. The value
ranges from 1 to 30. The default is 20.
background
User’s Manual
4-13
Fixed Processing: Used for black-and-
white and other high contrast documents. A
single level is set to determine the black-
and-white transition. The threshold is
programmable over the entire density
range. Fixed Processing sets Contrast to
0. If Fixed Processing is selected,
Contrast is not available.
Halftone: In addition to the black and
white display, Halftone can present a
somehow gray shade of image by using
different size of dots. Halftone image looks
like the picture we have seen in the
newspaper. Options include Halftone 1,
Halftone 2, Halftone 3, Halftone 4,
Halftone 5.
Error Diffusion: Error Diffusion is a type
of Halftone. Error Diffusion gives good
image texture and makes text in images
more readable than Halftone.

Threshold Used to convert a grayscale image to a
bi-tonal image. The value ranges from 0 to
255. A low threshold value produces a
lighter image, and can be used to subdue
backgrounds and subtle, unneeded
information. A high threshold value produces
a darker image, and can be used to help pick
up faint images.
Adjust the threshold setting by dragging the
Threshold sliding bar to the left or right to
achieve the desired threshold setting.

pure text or a mixture of text and graphic since it is an
optimal setting for regular business document. When
using Document, only Threshold can be adjusted.
Photo: Choose Photo if your original contains photo to
reproduce your photo in vivid grayscale image. When
using Photo, no Threshold and Contrast can be adjusted.
Normal: When using Normal, Threshold, Brightness, and
Contrast can be adjusted.
Threshold: The value ranges from 0 to 255. The default is
230. A low threshold value produces a lighter image, and can
be used to subdue backgrounds and subtle, unneeded
information. A high threshold value produces a darker image,
and can be used to help pick up faint images. Adjust the
threshold setting by dragging the Threshold sliding bar to the
left or right to achieve the desired threshold setting.

Resolution A good control of the resolution results a
good detail of an image that scans. The
resolution is measured by dots per inch
(dpi). Normally, the greater the dpi number,
the higher the resolution and the image file
size. Be aware that greater resolution takes
more time to scan, and more disk space for
the scanning image. For your information,
an A4 size color image scanned at 300 dpi at
True Color mode consumes approximately 25
MB of disk space. A higher resolution
(usually means over 600 dpi) is only
recommended when you need to scan a
small area at True Color mode.
Choose a resolution value from the drop
down list. The default value is 200 dpi.
Available resolutions are 75, 100, 150, 200,
300, 400 and 600. Or you may choose your
desired value by clicking the box in the right
side of the drop down list and press the
arrow key to select your desired value and
then click the Add button to include it in the
drop down list. Note: The resolution is up to
300 dpi if an imprinter or a MICR reader is
installed or connected to the scanner.

Merge Two Sides into One Image:
If you have a sheet-fed duplex scanner with

document with an innovative method. Thus,
fold your A3 size document into A4, and then
load the paper in the front tray. Choose
Merge Two Sides from the Scan Source

both sides of your document and merge two
A4 images into one A3 image.
When you select Merge Two Sides into One

4.4 The Compression Tab
The Compression tab allows you to compress your scanned
image and choose the level of compression. Bi-tonal images
are normally compressed using CCITT standard called Group 4
(G4). Color and grayscale images are often compressed using
JPEG technol
ogy. Move the JPEG Quality slider to the right or
left to increase or decrease the level of compression. Note the
greater the compression level, the lower image quality. Default
is 50%.
Note that the compression depends on your image editing
application. If your image editing application does not support
the type of compression format, then either a warning message
will appear or the image quality of the compressed file will not
be acceptable.
JPEG (Joint Photographic Editor Group). This group developed
and lent their name to a file compression standard for color and
grayscale images that is widely used by scanners, and software
applications. On Microsoft Windows-based systems, a file with
the extension .jpg has normally been compressed using this
standard.
For scanning color or gray images, the following compressions
are available:

Check thi

according to your document size when scanning non-standard
document (fragile, irregular-size document) with a carrier sheet
(optional). Note: The availability of this option varies due to
scanner model.
Loading Documents Using a Carrier Sheet
A Carrier Sheet is a plastic sheet specifically used for loading
non-standard document onto the scanner. It allows you to scan
document that can not be scanned in the regular way. Also,
documents larger than A4 size, such as A3 and B4, can be
scanned by folding in half, inserting into the Carrier Sheet, and
scanning in duplex mode. You can also scan documents that
can be damaged quite easily such as photographs, or irregular
size documents that are difficult to load directly such as
clippings.
To scan document using a Carrier Sheet,
For documents larger than A4/Letter size, such as A3
a. Fold the sheet to be scanned in half.
b. Fold the sheet tightly and smooth out crease. Otherwise,
the sheet may be skewed during scanning.
1. Open the Carrier Sheet and place the document
inside.
Align the top of the document to the top of the Carrier
Sheet (the printed area).

For documents larger than A4/letter size, such as
A3
Align the top of the document to the top of the Carrier
Sheet (the printed section) and the folded portion to the
right edge of the Carrier Sheet so that the document fits
into the Carrier Sheet at the upper corner.
For non-standard document
Center your document in the Carrier Sheet.
2. Load the Carrier Sheet with the gray section (printed
section) facing downwards.
3. Adjust the paper guides to the width of the Carrier Sheet.
Adjust the paper guides so that there is no space
between the guides and the Carrier sheet. Space between
the guides and Carrier Sheet may cause the Carrier Sheet
to become unaligned during scanning, and skew the
scanned image.
4. Start the scan.

Notice when scanning long page document:
1. Pull out the extension in the ADF Paper Tray.
2. Secure enough space around the Output Tray to prevent
the ejected paper from falling off the Output Tray.

mode, set the resolution to be 600 dpi or lower.
4. Depending on your system environments, application, or
your specified paper size, there may be insufficient
memory to perform scanning.
OverScan
Overscan allows you to add a specific margin at top and bottom
or right and left (Options vary based on the type of scanner) of
the edge of the image. This is used to reduce possible corner
clipping on the skewed images and often applied to a batch of
skewed document to be scanned in the auto document feeder.

measuring unit is pixel. The higher the number, the more
speckles will be removed.

always come out too dark?
Answer:
1) Please adjust the screen settings to
sRGB.
2) Please adjust the brightness
settings on the screen from
application software.
Question:
When I choose optical resolution
to be 600 dpi, the "auto crop" and
"deskew" functions will be
disabled.
Answer:
Since to perform auto crop and deskew
consumes great deal of system
memory, it is suggested if you wish to
perform "auto crop" and "deskew"
functions, please choose your optical
resolution to be smaller than 600 dpi
to prevent a error message.
