Front/Rear Auto Color Detection:

Click to automatically detect and scan the front or the rear
page of your color document in color image mode. If your
document is in colors, the scanner will automatically scan the
document into a color image. If your document is non-color,
you can choose the output to be either B&W or Gray from the
Non-Color Selection option. This option is useful when you
have a mixture of color and non-color document.
Note: If you choose Front Rear Auto Color Detection, you can
not specify the image mode of your rear page and vice versas.

Sensitivity of Auto Color Detection

If your documents contain primarily B&W text and small
amount of light or pale colors and you do not wish them to be
recognized as color image to save the file size, you can reduce
the sensitivity value by moving the bar to the left to let these
images to be detected as B&W. The value ranges from 1 to 30.
The default is 20.

3.2.2 Other Image Options

Binarization This 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, 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.

Sensitivity of Dynamic Threshold

Occasionally your scanned image may
contain small dots or speckles. To remove
these spots, increase the sensitivit y value
by moving the bar to the right. The value
ranges from 1 to 30. The default is 20.

User’s Manual

3-9

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.

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

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.

3.3 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 technology. 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:

 None
 JPEG

For scanning B&W images, the following compressions are

available:

 None

Automatic

Multiple

This option allows you to place various
sized documents such as photos, ID Cards,
or business cards on the flatbed (if
available) and lets you create multiple
individually cropped images in one scan.
Note: To correctly create multiple images,
please make sure there is at least 12mm
(0.5”) of space between each document.

Relative to

Document

This option allows you to crop different
areas on your documents and deliver these
images in B&W, Gray, or Color separately.
For example, there are applications which
require you to store the entire document in
B&W and a part of the document in color to
save storage space. This is useful for
documents where a photograph or
signature appears in a consistent area on
the document such as resumes, and so on.

The following options are only available when Fixed to
Transport is selected.

 X-Offset — the distance fr om the left end of the scanner

to the left edge of the scanning area.

 Y-Offset — the position from the top end of the

document to the top end of the scanning area.

 Width — the width of the scanning area.
 Length — the length of the scanning area.
 Center: automatically calculates the x-offset for center-fed

feeding based upon document size selected.

 — relocate the scan area by click the arrow key on

the cross sign while retain the scan size. View the result

Additional Length Detection is best used when scanning
same-size documents in the auto document feeder.

Intelligent Mode (Skip Multi-Feed) By Ultrasonic
Detection

Some documents which are glued with a photo or a label may
easily be detected as multi-feed yet you wish to bypass these
multi-feed conditions. In this case, you can use the intelligent
mode to let the scanner memorizes and skips these multi-feed
conditions. Choice includes Disable, By

Length(Paper/Object), By Position, By
Length(Paper/Object)+Position.

By Length (Paper/Object): When a multi-feed is detected

for the first time, the scanner memorizes both the length of the
document and the length of the object (photo or label)
attached to the document. When you perform next scanning,
this pattern of multi-feed will be bypassed.

By Position: When a multi-feed is detected for the first time,
the scanner memorizes the position of the photo or label
attached to the document. When you perform next scanning,
this pattern of multi-feed will be bypassed.

User’s Manual

Answer: 1) Use your application to modify the

Gamma setting to 2.2 and 1.8 for your
printer and monitor respectively.

2) Adjust Brightness setting from the
TWAIN interface to get a brighter
image.

Question: When I choose 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.
