Scan Settings
The Main Tab
The Main tab allows you to control the scanning
parameters, such as scan mode, scan source, resolution,
etc. These parameters determine how the original image
or document will be scanned.
Scan Mode
The Scan Mode determines how the scanner reads the
original image or document. When choosing a scan
mode, it is recommended to consider what purpose
the resulting scanned image will be used for.
• LineArt
Use this mode to scan text documents
for use in OCR (Optical Character
Recognition) or when you wish to scan
black-and-white drawings.
• Gray
Select Gray to capture images in shades of gray.
• Color
Select Color to capture images in color.
12
Scan Source
The Scan Source setting is used to select the type of
document you will be scanning.
• Reflective

or text.
With the optional Transparency Adapter, you can also
scan Positive and Negative transparencies.
• Positive
Select Positive when scanning slides or transparencies.
• Negative
Select Negative when scanning film negatives or
similar negative transparencies.
NOTE: When scanning negative film, choose Negative
from the Scan Source item and the following Negative
dialog box will appear (might not be available on the
current version of the TWAIN Dialog Box you are using).
It allows you to set the brand of negative film you are
scanning (Kodak, Fuji, Konica), the ASA/ISO (100, 200,
400), and the outlet where you had the film developed
(Kodak Outlet, Fuji Outlet, Konica Outlet).
NOTE: When the brand of the negative film you are
scanning is not currently available, use Simple Inverted
Setting instead of User Enhanced Settings. Afterwards,
use your favourite Image Application Software to do any
image editing and enhancement.
Visualized Settings
If you have little idea how to adjust the settings, you can
use the visualization window to setup a negative scan
quickly. The original is placed in the center. Eight
variations are around the original. Select a better preview
from the eight variations, you can easily correct a scanned
image.
Scan Size
From the list of available sizes, select the size of
the document you wish to scan. Custom will
automatically be selected when you use the Crop
Frame to change the image area to be scanned.
Resolution
The Resolution, which is measured in dots per inch
(dpi), determines the appearance of the image as
it is displayed or printed. Images scanned at a
higher resolution capture more information and
therefore require more disk space for storage. You
can select from a wide range of preset resolutions.
75 dpi (400%) 300 dpi (400%)
13
• None
Choose None if you want to scan images of
photographic quality.
• Newspaper
Choose Newspaper when the image is made up of
coarse dot patterns commonly found in newspaper
photos.
• Magazine
Choose Magazine when scanning images
whose quality is similar to images found in
glossy or wax-coated magazines.
• Art Print
Choose Art Print when scanning images from
very high quality art prints that show only very
fine dots.
JPEG2000
JPEG2000 is the latest image compression
standard that usually provides smaller file size and
higher image quality than the original JPEG.
Descreen
A tool for reducing moiré patterns in
scanned images of originals that were
created by a halftone process. Moiré
patterns appear as unpleasant
interference patterns.
If you decided to save a file in JPEG2000 format,
you can send the file to JPEG2000 Viewer to
display it.
Whiten Background
Sometimes, you may be copying an aged text that turned
brown or a book printed on unbleached/recycled paper.
Doing so often results in light gray background. Select
this option to get rid of the unpleasant shade, that helps
to save ink or toner when you print it.
This function is only applicable when you are scanning
text in grayscale. A non-text original, say a photograph,
when scanned with this box checked, can look unnatural.
Color Match
This is an effective tool for ensuring that the colors
captured by the scanner more accurately reflect the actual
colors of the original image. Without color matching the
scanner captures a wider range of colors but these colors
may not accurately match the true colors of the original
image, making the scan appear different from the original.
Color Balance
This tool balances the lightest and darkest areas of an
image so that they are evenly distributed.
14
Output Scaling
Output scaling allows you to enlarge/shrink the
size of the final output image. Adjust the scaling
by using the slide bar or typing the desired setting
in the Output Scaling box. For example, setting
the Output Scaling to 200% will double the amount
of pixels contained in the image.
Width and Height
The Width and Height values show the dimensions
of the image area inside the Crop Frame. You can
change the measurement unit to centimeters or
inches.
Image Size
Image Size displays the amount of disk space
needed to display or save the image outlined by
the Crop Frame. The Image Size information is
automatically updated anytime you change any of
the scan settings or resize the Crop Frame.

15
The Enhance Tab
The Enhance tab contains preprocessing controls that can
be applied to the image before making the final scan. To
access the Enhance tab, click Enhance.
The Enhance tab contains two picture thumbnails
(Original and Sample) of the preview image, several
control settings, and a histogram of the image. Alterations
made to the enhance settings appear in the sample
thumbnail.

If you wish to see the effects of your changes in the
Preview Window, click on the Preview button.
Channel Selector
Channel refers to the red, green, and blue
colors that make up a color image. You can
choose to change the channels individually
or choose Master to change all channels
equally and simultaneously. An image in
Gray Mode has one channel.
Brightness Control
Using 255 steps, this tool allows you to adjust the overall
amount of light in the image. A value of –127 will make
the image appear very dark, whereas, a value of +127
will make the image appear very bright.
Brightness –50 Brightness 0 Brightness 50
automatically be replaced with the Preview image.
Contrast Control
Using 255 steps, this tool controls the disparity in tone
between the dark and light areas of an image. Positive values
create greater differences between dark and light areas of
the image, whereas, negative values create greater similarities
between the dark and light areas of the image.
Contrast –50 Contrast 0 Contrast 50
16
Eyedroppers
Preview Button
Click the Preview button to see any changes made to the
image. The changes will appear in the Preview window.
Level
You can easily use the level slider to adjust an image’s
contrast and brightness. You can drag the little white triangle
to control the amount of hightlights, and the black triangle
to the shadows, if you haven’t set the two values using the
eyedroppers. The gray triangle in the middle controls the
image’s midtone. After the highlight and shadow values are
determined, use the gray triangle to roughly control an
image’s contrast.
You can control each channel’s levels if you scan in RGB.
Eyedropper tools
Eyedroppers are used to identify an image’s hightlights and
shadows. Click on the darkest area that still contains detail
with the black eyedropper to set the shadow value. Any
darker parts will be regarded as black. And then the lightest
area with the white eyedropper to set the hightlight. This is
the first step to control an image’s overall tonal range.
17
Curve
If your original is too dark or too light, you lose vital detail
after scanning. You can fix them up using curves.
Curve function is applicable to grayscale and 24/48-bit
color images. Simply put, if you knew how to use Adobe®
Photoshop® or any other equivalent softwares’ curve
function, you can safely skip this section.
add/remove anchors
Applying a curve to an image is to enhance favored
brightness ranges at cost of others. Like you can enhance
the shadow at cost of the highlight and midtone. If done
properly, you can energize a dull image using curves without
sacrificing the overall image quality. To write a curve, simply
place an anchor on the diagonal line and adjust its position.
Add more anchors if you have to write a more complex
curve. You can also remove anchors.
To emphasis shadow, raise the anchor; to emphasis highlight,
lower the anchor; to emphasis midtone, write an S-shaped
curve; to decrease contrast, write an inverted S-curve.
Experts apply curves to individual channels to color-correct
an image. Usually this is done to a CMYK image to be
printed.
18
Hue/Saturation
If you knew HSB colorspace, you can also skip this section.
But if you don’t know it, there’s nothing wrong with you.
In plain English, hue roughly means color: red, yellow, green,
blue, purple; and saturation means a color’s purity. When a
maple leaf turns red, it changes hue. If you place a bright
blue cardboard outdoors, its color will fade, it will be less
and less saturated.
The Hue Slider is composed of two color bars. The upper
one is static and the lower one movable. Slide the latter,
and you will see the image shifts its overall coloring. This
function mostly affects loud colors, less on mute colors.
It does not change black, whte and gray.
The Saturation Slider lets you to adjust an image’s color
purity. Slide it to the left, the image becomes dull, like a
black and white photo. Slide it to the right, the image
becomes more colorful.
These two functions are disabled when scanning in
grayscale or 48-bit color.
The Filters Tab
The Filters tab contains special effect controls that allow
you to alter the image before making your final scan. To
access the Filters tab, click Filters.
The Filters tab also contains two thumbnails of the
previewed image. Any filter you choose will immediately
show its effect in the sample thumbnail.
19
None
No filter is applied if None (default setting) is selected.
Blur
The Blur filter smoothes the image by lightening the pixels
that are in sharp contrast to their neighboring pixels. The
amount of blur applied is controlled with the plus and
minus buttons.
Sharpen
The Sharpen filter enhances the detail in blurry images
by improving the focus and increasing the contrast in the
image. The amount of sharpness applied is controlled with
the plus and minus buttons.
20
Invert
The Invert filter transforms an image to its negative
by converting all color values to their opposites: whites
become black, blues become yellow, etc.
Flip
The Flip filter creates a mirror image of the original
by flipping the image horizontally.
Unsharp Mask
The Unsharp Mask filter detects sharp edges and color
boundaries and then emphasizes them.
Emboss
The Emboss filter makes the elements in an image
appear raised or sunken by reducing the color within
the image and tracing its edges with black.
About Tab
The About tab contains the current driver version
number, information about the interface device, and
the copyright notice. To access the About tab, click
About.
21
Using Batch Scan
Batch scanning is an easy way to multi-scan any part of your
document using a variety of scan settings (Certain application
programs do not support this function). Using Batch Scan
you can specify up to 10 scan regions or scan a single region
several times using different scan modes, resolutions, filters,
and more.
Batch Scan Controls
Create Batch Scan: allows the user to create a new
batch scan.
Duplicate Batch Scan: duplicates the selected batch
scan settings.
Delete Batch Scan: deletes a batch scan.
Exit Batch Scan: exits the batch scan box.
Batch Ahead/Back: These arrows allow
you to scroll through your batch job list.
The Batch Box contains the thumbnail image, DPI,
scan mode and image size of each batch scan. The
batch number (e.g., 1/3, number 1 out of three) is
always displayed at the top of the batch box along
with the Batch Scan Status.
22
To Perform a Batch Scan
1. Click on the Batch Scan button. The Batch
Scan dialog box appears.
2. In the TWAIN dialog box, set the desired
scan mode and resolution for the current
scan region.
3. Repeat steps 2 if you wish to create additional scan
regions.
4. Click Scan. The scanner will begin to scan the
batch jobs one after the other.
NOTE: Using the Batch Scan arrows allows you to view
different batch jobs.
NOTE: You can assign different scan sizes (A4, A5 or
custom) to each image separately.

Appendix B: Troubleshooting
NOTES:
• It is not possible to print and scan at the same time.
• Do not disassemble the device to fix problems!
• When not using the scanner for long periods of time,
you should unplug the power adapter from the
wall socket.
1. The computer fails to recognize the scanner.
Check to ensure the scanner is correctly connected to
the computer. Power off your computer and the
scanner, and reconnect them by carefully following
our hardware installation instructions.
2. The scan command is not executed.
The scanner cable may be connected loosely. Check
to ensure the scanner is correctly connected to the
computer.
3. Why do my images look blotchy or blurry?
If your scans are looking bad on screen, but printing
out satisfactorily, it could be your video driver that is
causing the problem. Try changing the resolution and
color settings in the “Display” portion of your
Windows® control panel (after first making sure that
you have the proper driver disks to restore your system
to the original settings). You should be using a driver
that provides 16+million colors, and a resolution of at
least 800 x 600.
4. What resolution should I scan at?
a. You should scan at the resolution of your output device.
b. If you plan to display your scans on a computer monitor
(Internet), which has a resolution of 72DPI, we
recommend scanning at 72 DPI.
c. If your output device is an inkjet printer:
• For color images,
scan at 1/3 the allowable resolution of the printer.
• For Gray Mode or Line Art images,
scan at the full resolution of the printer.
5. The scanned picture is not clear.
We recommend that you keep the scan window glass and
the document cover clean. They should be cleaned on a
regular basis. The cleaning steps are:
a. Turn off the scanner and unplug the power cord.
b. Open the document cover and use a cloth dampened with
alcohol to clean the scan window glass and the cover
separately.
c. Use a lint-free dry cloth to dry the glass and cover.
