b. Place the document face down on the glass and in the
upper right corner where the alignment arrow is
located.
(7) Click the Scan button.
c. Slowly lower the document cover, making sure the
document remains in position.
Note: Remove the document after scanning is complete.
(2) Preview the Image
A Preview is a quick low-resolution scan of the
entire original image. From this low-resolution
scan you get a clearer idea of the image area
you want to include in your final scan.
12
(3) Select the Scan Size
From the list of available paper 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.
(4) Use the Crop Frame
Use the Crop Frame in the Preview Window to
outline the image area you wish to scan. Click one
of the sides or corners of the Crop Frame and drag it
to the desired length and width. To move the entire
Crop Frame, position the mouse cursor inside it and
drag with the (left) mouse button. Only the area
inside the Crop Frame will be included in the
resulting scanned image when you click on the Scan
button.
(5) Set the Scan Mode

more information and therefore require more disk space
for storage. You can select from a wide range of preset
resolutions.
75 dpi 400 dpi
Descreen
A tool for reducing moiré patterns in
scanned images of originals that were
created by a halftone process. Moiré
patterns appear as unsightly interference
patterns.
• None
Choose None if you want to scan images of
photographic quality.
• Newspaper

coarse dot patterns commonly found in newspaper
photos.
• Magazine
Choose Magazine when scanning images whose
quality is similar to images found in glossy or waxcoated magazines.
• Art Print
Choose Art Print when scanning images from very
high quality art prints that show only very fine dots.
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 equally distributed.
19
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 in
the Preview window. The Image Size information is
automatically updated anytime you change any of the
scan settings or resize the Crop Frame.
Without Color Balance With Color Balance
20
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.
Thumbnails
The image that appears in the thumbnails will
automatically be replaced with the Preview image.
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.
Histogram
The Histogram graph shows the distribution of brightness
levels in an image. Using the control settings (Brightness,
Contrast, Gamma) you can selectively adjust the
brightness levels in the shadows, midtones and the
highlights of the image.
A diagonal line extending from
the lower left corner to the upper
right corner indicates there is a
balance between brightness and
shadows.
21
Using the Channel Selector allows the histogram to reflect
the distribution of brightness in an entire image or in
individual colors (Red, Green, and Blue).
Histogram Button
The Histogram Button allows you to view the
histogram as either a line graph or a bar graph.
As a bar graph, the horizontal axis represents
the brightness levels from darkest (left) to
brightest (right). The vertical axis represents
the amount of pixels with that brightness
level value. To adjust the display of the
histogram, click on the Histogram button
and then click on the + or - button.
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
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
Gamma Control
The Gamma control is used for adjusting the
brightness level in the highlights, mid-tones, and
shadows of the image. Values of 0.1 to 2.0
primarily affect the shadow areas of the image.
Values of 2.1 to 6.0 primarily affect the midtone
areas, and values of 6.1 to 7.9 primarily affect the
highlight areas.
For Example: A gamma value of 1.9 will make the shadows
of an image appear brighter, whereas, a value of 0.2 would
darken these shadow areas (taking away brightness). The
histogram graph will display these gamma value effects
in the bottom right portion of the histogram graph
22
(signifying shadows). A gamma value of 7.8 will add light to
the highlight areas of the image (making the image appear
bright), whereas, a value of 6.4 would subtract light from
these highlight areas. The histogram will display these
gamma value effects in the top left portion of the histogram
graph (signifying highlights).
Gamma 0.6 Gamma 1.5
Preview Button
Click the Preview button to see any changes made to the
image. The changes will appear in the Preview window.
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.
23
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.
The Filters tab also contains two thumbnails of the
previewed image. Any filter you choose will immediately
show its effect in the sample thumbnail.
24
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.
25
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
Load Batch Scan: loads previously saved batch scan
settings.
Save Batch Scan: saves the current batch scan
settings.
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.
26
The Batch Box contains the thumbnail image,
DPI, scan mode and image size of each batch
scan. The batch number (e.g. 1/10, number 1
out of ten) is always displayed at the top of
the batch box along with the Batch Scan
Status.
Batch Scan Status
Batch Scan Completed: The medium green light at
the top of the image means that the scanner has
completed the batch job.
Batch Scan in Progress: The bright green light at

Appendices
Appendix A: Scanning Tips
The following tables provide helpful information you
can use when setting the scan mode and/or resolution.
Recommended scanning resolutions for various output
devices are listed as follows:
27
Space requirements for different scan modes:
28
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
(Intrenet), 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 Lineart 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.
Note: Please refer to one of our web sites for more
troubleshooting tips (F
requently Asked Questions).
