Introduction to ScanGear CS-S 4.3
Welcome to ScanGear CS-S
Welcome to Canon ScanGear CS-S 4.3 for Windows 95, Windows 98 and
Windows NT 4.0! Working with your imaging application, the ScanGear CS-S
provides flexible capabilities for scanning with your Canon scanner and
interfacing with a wide variety of applications and devices. ScanGear CS-S
also gives you prescan image enhancement features and lets you produce
professional-quality images from your scanner.
System Requirements
Before you run install ScanGear CS-S, make sure your hardware and software
meet the system requirements listed below.
Hardware
• CPU:
• RAM:
i486 or greater (Windows 95/98)
Pentium or greater (Windows NT 4.0)
32 MB or greater; 64 MB recommended (Windows 95)
32 MB or greater; 64 MB recommended (Windows 98)
32 MB or greater; 64 MB recommended (Windows NT 4.0)
• Data files: 50 MB or greater free space
The size of scanned images varies depending on the image type selected.
Black and white scans have the smallest file size; high-resolution color
scans have the largest file size. As an example, a 4 inches x 6 inches color
photograph scanned in high-resolution color at 600 dpi needs about 25
MB of hard disk space. For more information about scanned image file
sizes, see Chapter 5, “Scanning Techniques.”
• Program files: 3 MB required
• Monitor: Super VGA, 256 or more colors, 800 X 600 or higher
resolution.
For previewing the best color scans, it is recommended that you make sure
your monitor’s color palette is set to Full Color (24 bit).
• ASPI-compatible SCSI card
A compatible SCSI card is bundled with your scanner.

Software
Windows® 95, Windows® 98 or Windows NT® 4.0 is required to run the
ScanGear CS-S. It is also recommended that you install the latest available
Windows 95/98 or Windows NT 4.0 Service Pack.
About ScanGear CS-S
ScanGear CS-S has a number of powerful features that help you get the most
out of your scanner’s capabilities. Using ScanGear CS-S, you can preview an
image and make changes before the image is scanned and acquired by the
application you are using.
Feature List
The following list describes some of ScanGear CS-S’s features:
• Flexible, fully automatic image acquisition, and pre-scan image
manipulation prior to passing data to the image application
• Sophisticated, Windows-compliant user interface
• Full support of TWAIN 1.6 specifications
• Support for Automatic Document Feeder (ADF) option
• Text Enhanced mode for OCR(optical character recognition)
applications
• Canon ColorGearTM Color Matching software technology
About ScanGear CS-S “Windowless” Mode
The ScanGear CS-S data source runs with or without its window (user
interface, or UI) displayed, depending on the acquiring application. When an
application requests a scan and the ScanGear CS-S window does not appear
before the scan occurs, you can not use the ScanGear CS-S settings described
in this manual. The host application provides the settings, and you can change
the image after it is acquired. This is called “windowless” or “UI-less”
scanning mode.

Selecting ScanGear CS-S
ScanGear CS-S can be called from any TWAIN-compliant application, such as
an imaging or OCR application.
Because the TWAIN-compliant application may install older TWAIN files than
ScanGear CS-S’s, it is recommended that the application be installed first,
before ScanGear CS-S.
If you have installed other TWAIN drivers on your computer, you may select it
as your default TWAIN source by using the application’s ‘File/Acquire/Select
TWAIN_32 Source’ menu option or its equivalent. Once you have selected
ScanGear CS-S as your source, choosing the command to scan, such as ‘File/
Acquire’, or ‘File/Scan’ will automatically start ScanGear CS-S in the
application.
Removing ScanGear CS-S
If you need to remove ScanGear CS-S from your system, use the following
steps to make sure all files are removed from all locations.
To remove ScanGear CS-S from your computer:
1. Place the CanoScan Setup CD-ROM in the computer drive.
2. In the start-up menu, click [Install/Uninstall Software].
3. [Install] window is displayed. Check the check box for [ScanGear CS-S] and
click [Uninstall] in the top-left of the window.
4. Click [Open the Add/Delete Programs dialog] in the bottom-right of the
window.
5. In the [Add/Remove Programs Properties] dialog box, make sure the
[Install/Uninstall] tab is in front, then select Canon ScanGear CS-S 4.3 and

About Scanning
Scanning is the process of converting an image into computer-usable
information that is, digitizing the image. Scanners and digital cameras are the
main examples of devices that have the technology to transfer an external
image to digital information that can be saved as a file, printed, faxed, or
otherwise manipulated on your computer.
Until the introduction of digital cameras, scanners were the usual means of
turning a photograph or other printed graphic into computer compatible
information. Digital cameras use a similar process. Instead of exposing the
image in its lens to photoreactive film, the shape, color and shading
information is translated to a computer file. ScanGear CS-S lets you
manipulate the digital information before the image is saved or sent to its
final destination.
Using ScanGear CS-S with an Application
ScanGear CS-S is an interface between the scanner hardware and an imaging
application on your computer. With ScanGear CS-S, you can scan images
directly into an application without any interaction, or you can preview the
image and make changes to the way the scan is performed that affect the
resulting image.
You can also scan printed text and, when the Text Enhanced feature is
enabled, help your optical character recognition (OCR) software to recognize
text more effectively.
The TWAIN Interface
ScanGear CS-S is TWAIN-compliant. TWAIN refers to the set of standards that
define how information should be passed from image acquisition devices such
as scanners to software imaging applications that have the ability to import
TWAIN-compliant scanned images.
A graphics application is a typical example of a program that supports TWAIN
drivers. When you have a TWAIN-compliant application, scanner, and scanner
driver, you can scan an image directly into that application.

CONTENTS
GLOSSARY

17
You can choose to scan the image without changing the default scan settings,
or you can use ScanGear CS-S’s settings to preview and adjust a variety of
settings prior to scanning. ScanGear CS-S’s settings are also dependent on
your scanner’s capabilities and the capabilities of the imaging application you
are using.
Acquiring an Image
When an application receives a scanned image directly from a scan, it is
acquiring the image. Throughout this manual, you will see references to
“acquiring an image.” This means that an application is using ScanGear CS-S
to import the image from the scanner; so it is acquiring the image from the
scanner via ScanGear CS-S.
Features of the ScanGear CS-S Window
The main ScanGear CS-S window is used to preview, adjust, and scan images
when the acquiring software lets you preview the image before scanning. For
details on applications that do not open the ScanGear CS-S window, see
“Scanning in “Windowless” (UI-less) Mode.”

The Preview Area
The preview area lets you “prescan” an image before it is scanned and
acquired by the application. The preview shows how the scanned image will
look after you scan.
When an image is previewed, you can use the tools on the toolbar to select a
portion of the image to scan, rotate or resize the image, or view the image’s
appearance after you make changes to the scanning mode, tone, or other
settings. The horizontal and vertical rulers, selectable on the toolbar, let you
see the dimensions of the image.

Clear, Preview and Scan Buttons
The Clear, Preview and Scan buttons control the scanner. When you click
Clear, the image displayed in the preview area is cleared. When you click
Preview, the image on the scanner is scanned into the preview area but not
yet saved in the acquiring application. When you click Scan, the image
displayed in the preview area is scanned and sent to the acquiring application.
For details, see “Previewing an Image,” later in this chapter.
Toolbar
The toolbar has a set of tools that let you change the previewed image’s
shape and size. You can rotate the image, select a part of the image, zoom in
and out, create a negative image, flip an image, and turn rulers on and off.
For full details on these tools and their functions, see “Changing the Preview
Image Shape and Size,” later in this chapter.
Status and Message Areas
The status area at the bottom of the ScanGear CS-S window summarizes the
color mode, resolution, width and height, and the estimated file size of the
currently previewed image when it is acquired by the application. For more
information on estimating file sizes, see Chapter 5, “Scanning Techniques.”
The message area on the lower left of the window displays messages related
to the preview area and toolbar.
Settings Tabs
Each tab (Main, Tone, Preferences, and the device tab) contains settings that
let you modify the acquired image.
For information about the settings on the Main tab, see “Setting Scan Mode,
Resolution, and Dimensions.” For information about the settings on the Tone
tab, see “Setting Image Tones.” For information about the Preferences tab
settings, see “Setting General Preferences.” For information about the
FB1200S tab, see Chapter 4, “Scanning Devices.”

Quick Start to Scanning
Use these steps to get going with ScanGear CS-S quickly, with the installed
settings.
Note:
ScanGear CS-S does not launch unless a scanner is powered on
and recognized by Windows.
Preparing the Scanner
Before you start scanning, be sure the scanner is connected and powered on.
It is recommended that you power on your scanner before you turn on your
PC. If you want to ensure that the scanner is functioning correctly, run the
Test Scanner from FB1200S tab. See “Testing the Scanner” in Chapter 4,
“Scanning Devices.”
Place the item to be scanned image side down, and position it squarely on the
platen.
Previewing an Image
The advantage of using ScanGear CS-S is that you can preview the image and
make changes before actually scanning. That way, you can make sure you are
getting the most out of your scanner’s capabilities and of your time spent
scanning and working with the image.
Some applications, (for example OCR applications) do not require the
ScanGear CS-S window to open before the scan starts. However, ScanGear
CS-S has settings such as Text Enhanced that automatically give you the best
available scan without previewing the image.
To preview an image:
1. Place the item to be scanned on the scanner.
2. You must select a source if you have not already done so. On the menu of
your imaging application, use the command that selects the data source.
On many imaging applications, the menu item looks similar to the
following picture:
In the Imaging application that is included in the Windows 95/98
Accessories, the command is “Select Scanner” on the File menu.

3. Select the source of the scan, and click Select (or OK).
Now you are ready to acquire the image.
4. On the menu of your imaging application, select the command that begins
the scanning process. On some applications, this is “Acquire/Image;” in the
Windows 95/98 Imaging application, it is “Scan New.”
Unless you are using ScanGear CS-S in “windowless” mode, the ScanGear
CS-S window appears.
Previewing starts automatically (Auto Preview is switched on at default
settings).
The ScanGear CS-S main window opens, scanning begins automatically,
and preview begins. When preview is finished, the preview image is
displayed in the Preview Area.
When Auto Preview is switched off in the basic settings, click the Preview
button to start image preview.

a scan, you can click Cancel on the progress dialog box.
Calibration will automatically be performed before scanning.
7. To adjust the image in the preview area, do one or more of the following:
• The Crop tool is selected automatically when you launch ScanGear CSS. If there is white space around your preview image, crop the image to
eliminate the white space and any other unwanted part of the image. If
you do not crop the image, the white space is included in the final
scan. For details, see “Cropping Part of an Image” later in this chapter.
• To view the image dimensions in the preview area, click the Rulers
button to display the horizontal and vertical rulers.
• Use the Zoom tool to zoom in before you crop. See “Zooming In and
Out,” later in this chapter. You can also use the Width and Height text
boxes on the Main tab in conjunction with the Crop tool to make your
selection more precise. If you want the acquired image to be larger or
smaller than the current preview size, use the Scale setting to set a
different percentage. For more information about zooming and scan
resolution, see Chapter 5, “Scanning Techniques.”
• Adjust the Contrast/Brightness, Gamma, or other tone settings to
adjust the image tone. When you adjust tone settings, you see the
results immediately in the preview image. For more information, see

Where is the Scanned Image?
Once scanned, an image becomes one of the acquiring application’s open
files. If you launched ScanGear CS-S from a TWAIN-compliant program,
clicking the Scan button also saved the image in the format determined by
the application from which ScanGear CS-S was launched.
Scanning in “Windowless” (UI-less) Mode
Some applications use ScanGear CS-S without opening the ScanGear CS-S
window (the user interface, or UI). These applications include Pagis, Microsoft
MS Picture It!, and most OCR (Optical Character Recognition) software. If you
are using software that does not open the ScanGear CS-S window, you are
unable to use any of the features on the ScanGear CS-S window. However,
with some applications, you may be able to perform a “custom” scan that will
open the ScanGear CS-S window.
For applications that do not show the ScanGear CS-S window, ScanGear CS-S
automatically uses the settings determined by the application that will
perform the scan with optimal results. Follow the instructions in your
application to scan the images.

Cropping Part of an Image
Click Crop and drag diagonally across an area of the image in the Preview
window to select that area. The area you select is outlined with a broken line.
You can adjust the crop lines once you have selected an area. If you hold the
cursor over the selection handle in the middle of a crop line, a two-headed
arrow appears. You can drag the line in or out to adjust the width and height
of the image.
Click outside the broken line to crop a different area.
• If you crop too small an area, the size resets.
• If you type new values in the Width and Height text boxes, the selected
preview area changes. If the Keep Proportions button is turned on
when you select a new area (you see a chain between the Width and
Height boxes), the proportions match the last locked proportion.
• The minimum scan width and height varies depending upon the scan
resolution selected. For example, at 75 dpi, the minimum width and
height is 9 pixels (approximately 0.12 inches or 0.30 cm) for a preview
scan. At 300 dpi, the minimum width and height is 35 pixels
(approximately 0.12 inches or 0.30 cm) for a preview scan.
Note:
If your mouse has left-handed settings, the right and left
mouse settings for ScanGear CS-S tools are reversed.

Setting Scan Mode, Resolution, and Dimensions
When ScanGear CS-S is installed, the settings are in place and you can scan
without changing them. However, there are a wide variety of options available
for you to change the look of the preview and scanned image. You can
change the settings at any time and preview the results. Repeat this process
until you are ready to complete the scan. Some changes (Tone tab settings
and output size) take effect immediately and can be seen on the preview
image; some changes (changing the scan mode) require that you click the
Preview button again.
The primary settings for image acquisition, including scanning mode,
resolution and scanning area, are on the Main tab.
Setting Scanning Mode
The scanning mode-Black and White-affects the settings on all the other tabs.
The icon to the left of the list box reflects the current selection.

To set scanning mode:
1. Click the Main tab.
2. Select an option from the Scan Mode list. You have the following choices:
• Color (36-bit): 36-bit color images contain 12 bits per pixel for each
primary color (red, green, blue). Use this option to attain a scanned
color image of the highest quality. However, the file will be
approximately twice the size of a Color (24-bit) file.
• Color (24-bit): 24-bit color images contain 8 bits per pixel for each
primary color. Use this option to attain a scanned color image of
average quality.
• Grayscale (12-bit): 12-bit grayscale images contain 12 bits per pixel.
Use this option to attain a scanned grayscale image of the highest
quality. However, the file will be approximately twice the size of a
Grayscale (8-bit) file.
• Grayscale (8-bit): 8-bit grayscale images contain 8 bits per pixel. Use
this option to attain a grayscale image of average quality.
• Black and White: Images are expressed in two colors only; black or
white. A pixel is set to black or white depending on its brightness value
in relation to a particular threshold value. The threshold value can be
freely set. Select this option to print photographs on monochrome
printers.
• Text Enhanced: Text Enhanced images are Grayscale images (8 bits per
pixel) converted to Black and White (1 bit per pixel) using Canon
ImageTrust technology. You can select Text Enhanced in the Scan
Mode list. If the application operates in windowless (UI-less) mode, you
can select “Text Enhanced” in the Preferences tab, and request the
application to perform a Black and White scan. In this case, the
conversion to Black and White takes place automatically.
The acquiring application may determine your Scan Mode choice. For
example, if a fax application is acquiring the image, you may not be able to
choose a color mode; you may have to choose Black and White or Grayscale.
The 24-bit and 36-bit options express colors with conversions of each primary
RGB color (Red, Green, Blue). The 24-bit options can express each color with
up to 256 gradations, and 36-bit color with up to 4,096 gradations. If you
need extremely high-quality color gradation in the scanned image, use 36-bit
color. Otherwise, use 24-bit for normal color scanning jobs.

The Grayscale options express varying shades of gray between white and
black. The Grayscale (8-bit) option can express shades within a range of 256
gradations and the Grayscale (12-bit) option within a range of 4,096
gradations.
If you attempt to use the Color (36-bit) or Grayscale (12-bit) options to scan
an image with a software application that does not support these options, the
system may hang up. Before you use either 36-bit or 12-bit grayscale, check
the specifications of the parent software application to confirm whether these
options can be used. You can use Color (36-bit) and Grayscale (12-bit) with
Photoshop Ver. 4.0 or later and with Photoshop LE enclosed with this
package.
If you scan an image with a version of Photoshop compatible with 36-bit color
and 12-bit grayscale, the image is scanned as a 16-bit Channel Mode image.
Selecting Scan Resolution
Using the Scan Resolution list, you can select the resolution of a scanned
image based on the selected output device. This resolution becomes the base
on which changes to image size and scale are calculated.
The resolution you choose depends on the limits of the printer or other
output device. However, you can also select a custom resolution and make
more specific resolution choices.
Note:
The maximum resolution of the scanner is set at 600 dpi when
the optional automatic document feeder (ADF) is installed.
Selecting a Preset Resolution
The list of preset resolutions should cover most of your scanning needs.
Available resolution settings depend on the capabilities of the acquiring
application.
To select a preset scan resolution:
Select an option from the Scan Resolution list.
Depending on your selected device, you have different resolution choices. For
example, if the acquiring application is configured to print the image, your
choices may be limited to the printer’s maximum resolution.

Setting Units of Measurement
In the Units list, you specify the unit of measure for width and height of the
scanned image. The preset unit of measurement is based on the
Measurement System setting of the Regional Settings in your Windows
Control Panel.
To set units of measurement, select Inches, Centimeters, or Pixels in the Units
list. The Width and Height values display in the units you choose.
There is no change to the size of the selection rectangle in the preview area
when units of measurement are changed, but the horizontal and vertical
rulers reflect the currently selected measurement units. For example if you
select Centimeters, the default Width value of 8.49 inches changes to 21.57
centimeters.
Setting Image Width and Height
The Width and Height text boxes contain the width and height of the current
selection or, if there is no selection, the maximum output size, measured from
the upper left of the image in the preview area and based on the currently
selected paper size.
The width and height values change when you select part of the image in the
preview area. Correspondingly, when you change the amounts in the Width
and Height boxes, the selection borders in the preview area change to match.
To change size without constraint, do one of the following:
• Click the Crop button on the toolbar and select a section of the image
in the preview area. The measurements in the Width and Height text
boxes display the new sizes.
• Type the desired measurements in the Width and Height text boxes.
The image selection borders change to match the width and height you
enter.
Maintaining Image Proportion
The Keep Proportions button

When you click the Keep Proportions button, the image size is maintained in
the same proportion whenever you change either the width or the height.
Keep Proportions active
For example, if you set the width to 4 inches and the height to 6 inches, and
then you change the width to 5 inches, the height stays at 6 inches if the
constraint is turned off, so the proportion of the image width and height
changes. If you click the Keep Proportions button and then change the width,
the height automatically changes to 7.50 inches.
When the Keep Proportions button is selected, the image maintains the same
ratio indicated in the Width and Height text boxes.
To change size proportionally:
1. Click the Keep Proportions button.
A chain appears between the Width and Height text boxes.
2. Click the Crop button on the toolbar and select part of the image in the
preview area.
When you enlarge or reduce the selection, notice that the image width
and height stay in the same proportion.
Setting Scale
The Scale setting lets you specify an output size for the selected image as a
percentage of the original width and height. The scale amount is preset to
100 percent.
If you reduce the scale of an image that has a width of 7 inches and a height
of 9 inches by 50 percent, the selection in the preview area and the values in
the Width and Height text boxes remain the same, but the Output size
changes to indicate the size of the image when it is acquired by the
application. For example, if your preview image is 7 inches wide by 9 inches
high, and you select a scale of 50 percent, the output image will be 3.5 inches
wide by 4.5 inches high.

Setting Image Tones
The Tone tab contains settings that govern the image tone. “Tone” refers to
the shading and combination of colors in the image.
Adjusting colors and grayscale tones can enhance the richness of a color
image or the contrast of a grayscale image. You can produce a wide range of
visual effects for your preview image by adjusting the different settings on the
Tone tab.
Note:
If you selected Black and White or Text Enhanced as the Scan
Mode on the Main tab, the Tone tab is not visible.
About the Tone Tab Settings

About the Tone Curve Window
The Tone Curve windows display more details about each tone setting. The
shape of the tone curve changes to reflect the current settings in the selected
channel. If Scan Mode is Color or Grayscale, and the Tone tab is selected,
Contrast/Brightness is the Tone feature selected and displayed, by default. The
curve is not directly editable unless the Special Tone Curves tool is active.
Selecting a Color Channel
If you are scanning a color image, you can change the contrast and brightness
of the individual red, green, and blue tones in your image.
The Channel list has the following options:
Master
Red

3. Position your cursor over the handle. The cursor becomes a crosshair,
indicating that you can drag the curve handle. Drag the handle and
release. The curve remains where you moved it, and the image in the
preview area reflects the change in tone. You can specify up to 15 anchor
points, including the end points.
4. Because the curve reflects mathematical calculations related to the image
tones, it does not move exactly where you want. You can move the curve
in the following ways:
• Drag a curve handle up or down.
• Click on another part of the curve to set a new handle. You can have
as many handles as you want. However, it is best to experiment and set
your handles at points in the curve where you want to bend it.
• To remove a handle, drag it off the curve, or right-click the handle.
5. Click Reset to undo a change to the curve.
6. Click Save to save your custom curve.
7. Specify a file name and click OK.
The curve is saved in the location you specify.

Opening a Saved Custom Tone Curve
Use the following steps to open a custom tone curve setting that you saved
previously. Custom Tone Curve files are saved by default in the ScanGear CS-S
device-specific directory, although you may choose another location.
To apply a previously saved curve:
1. Click Load.
2. Select the file name you want to load and apply.
3. Double-click the file, or click Open.
Hints for Editing Custom Tone Curves
You can choose a channel and begin to edit the custom curve with the
automatic curves as a starting point. Keep the following in mind when editing
a custom curve:
• The curve box handles are drawn on a white background to signify
that they are editable.
• The curve end points can be selected and dragged to any point in
the curve.
• You may add points to the curve by clicking anywhere in the curve
box.
• If a point is dragged outside of the curve box, it is deleted from the
curve and a new curve is fit to the remaining points.
• The x and y axes on the curve chart represent the input image color
and output image color. When you add a handle to the curve and
drag that handle toward the white areas, the preview image tones
are adjusted to reflect the change.
• You cannot position two handles on a vertical line, because you
cannot have two of the same x values due to the mathematical
formulas involved in drawing the curves. However, you can have
two or more of the same y values, so you can have several handles
on a horizontal line.
• The least and greatest x values for end points, whether original or
added, cannot be deleted.

About Canon ColorGear Color Matching
Canon ColorGear Color Matching is the universal color-matching system for
Canon printers, copiers, and scanners that makes predictable color available
for all levels of users, from home user to professional publisher.
Canon ColorGear Color Matching provides RGB to CYMK conversions that
are optimized for Canon scanners, printers, and copiers. Canon ColorGear
Color Matching also enhances and optimizes the monitors of most other
manufacturers.
With some printers, there is a discrepancy between the color image displayed
on a computer monitor and the same image printed on a color printer. The
color printout is disappointing because the colors are duller, or the color does
not match the color on the screen. Canon ColorGear Color Matching ensures
that this does not happen.
Canon ColorGear Color Matching is compliant with ICC (International Color
Consortium) guidelines. ICC is a group of hardware and software companies
which developed cross-platform, industry-standard guidelines for color
devices. Canon ColorGear Color Matching is also compatible with the ICM
(Image Color Matching) component of Windows 95/98/NT.

Adjusting Threshold Setting
The Threshold slider can be used to adjust the threshold value (the
demarcation between black and white) of black and white images. Images are
collection of data assigned varying brightness values. Grayscale and Color
images express the brightness with 8 or 12 bit values whereas Black and
White images express the brightness with only two values, black (0) and white
(255). Accordingly, a point has to be determined either black or white. This
point is called the threshold value. By changing the threshold value, you can
alter the appearance of image. The default setting is 128.
To adjust threshold value, drag the slider or input the value directly into the
box (click the box and type the number from 0 to 255) in FB1200S tab.
Selecting the Descreen
Moiré patterns occasionally appear when items printed at high resolutions are
scanned. To reduce this phenomenon, scan photographs and other highresolution prints with the descreen activated. Shut it off to scan lower
resolution items, such as newspapers, books and magazine text. The default
setting is "Off."
• The Descreen is unavailable when the scanning resolution is set for 601

Scanning Multi-Page Documents
If you use a flatbed scanner, you can scan and acquire many pages of
documents at a time. ScanGear CS-S has settings to support the use of the
automatic document feeder (ADF). When you have an automatic document
feeder attached, ScanGear CS-S controls the feeder during the scan.
Using the Automatic Document Feeder (ADF)
Use the following steps to have ScanGear CS-S scan multiple documents
using a document feeder. For details on loading the document feeder, see its
documentation.
Connecting the Automatic Document Feeder
The Automatic Document Feeder replaces the document cover on a flatbed
scanner. You must remove the document cover and replace it with the ADF,
and attach a connector plug.
To connect the Automatic Document Feeder:
1. Remove the document cover from the scanner and set aside in a safe place
where the inside document cover will not be scratched.
2. Disconnect the power cord.
3. Insert the hinges of the ADF in the scanner and make sure the ADF is
securely seated.
4. Plug the adapter cord in the Options port on the back of the scanner.
5. Reconnect the power cord.
6. Turn on the scanner. You should hear the ADF initializing.
7. Turn on your PC.
Now you are ready to scan.

9. Do one of the following:
• Click Preview to preview a page before scanning the remainder. You
will have to re-load this page in the feeder to scan it.
• Click Scan to scan all the pages in the feeder tray with no further
intervention. In a graphics imaging application, each page is acquired
as a separate file. In some OCR applications, each page is acquired as a
separate file, while in other OCR applications, each page is appended
into one file.
Tips for Using the Automatic Document Feeder
Here are some tips for using the Automatic Document Feeder
• Make sure Document Feeder is selected in the Image Source setting on
the scanner’s settings tab.
• If there is a paper jam message, make sure the paper in the document
tray is not stuck together. Open the ADF cover (do not lift up the entire
ADF unit), remove the paper, close the lid, and reload the paper. Only a
few documents should be loaded in the document tray at a time.
• Make sure no other document has been left on the document glass
under the Document Feeder.
• If you see a message on the screen that says something like this:
“Device failed/cannot find TWAIN...” make sure you have turned on
your scanner first, before your PC. If necessary, turn the scanner off and
back on again.
• If the Document Feeder tries to feed but cannot, and you hear a
bumping noise in the scanner, check that the scanner’s scanning head
is not locked. If you have just unpacked your scanner, this lock may be
in place to protect the scanning head. See your scanner documentation
for details.
• Documents are scanned from top to bottom order.
• Select the proper Paper Size from the device tab.

About Scanning Techniques
This chapter provides additional information about scanning theory and
practice. It has basic information to help get the most out of ScanGear CS-S’s
tools, and to help you make the right choices before scanning your images.
Using the information in this chapter in conjunction with the information in
Chapter 3, “Scanning,” should let you produce effective results from your
scans.
Planning for the End Result
The settings you use to scan depend on the purpose of the scan. Will the
result be printed on a color printer, be included in an Internet web site, or be
used for professional color magazine printing? Is an OCR application acquiring
the scanned image for conversion to text? All these target destinations have
different requirements for color mode, resolution, and tone.
Preparing the Material to Scan
A general rule of image reproduction is that the output image can be only as
good as the original. Anything you can do to lessen the manipulation
between the original and the end result will give you a better quality product.
If the original image needs correction - for example, it is overexposed,
underexposed, or blurry - more time will be needed to make the correction,
and the results may still be limited by the flaws of the original image.
ScanGear CS-S lets you correct many undesirable features in scanned images,
but you will save time and effort by starting with the best possible original
image.
• Although ScanGear CS-S’s Tone tab lets you adjust for over- and
underexposed images and other tone problems, it cannot bring a
blurry image into focus, and “sharpen” options in the imaging
software can only do so much with a blurry original. If you are
scanning a photograph or other reproduced image, make sure the
original is in the sharpest possible focus or delineation.
• If you are scanning text, make sure the print is clearly defined.

Chapter 5

GLOSSARY

• Although it may seem obvious, it is important to line up the original
as straight as possible so you do not have to make adjustments in
the scan.
• If you plan to rotate the image in the ScanGear CS-S preview
window or in the acquiring software, try positioning the image so it
is already rotated before the scan.
Matching Scan Resolution to Purpose
ScanGear CS-S provides many choices for resolution. What resolution you
choose depends on your output device, how you want to use the image, the
type of image, and your scanner.
In general, it is recommended that you scan the image at a higher resolution
than you need. That way, you retain the amount of information in the image,
and if necessary you can reduce the resolution in the imaging application,
after the image has been scanned and acquired.
Different types of images need different types of scan settings. However, after
a certain point, increases in scan resolution will not improve the output image
quality. For example, a text image can be scanned at 600 dpi for output to a
600 dpi laser printer, but a color image should be scanned at 180 dpi to be
output to a color BJ-printer. When the image is output to a Bubble jet printer
in the color or gray mode, for example, the basic resolution of the printer is
halved. For example, for a 360 dpi printer the basic resolution is set for 180
dpi.
• If your image is black and white with no shades of gray, such as line
art, scan in Black and White mode.
• If you are scanning a text image for conversion to a text file, scan in
Text Enhanced mode.
• If you are scanning continuous-tone black and white photographs,
charcoal drawings, or any original with shades of gray, scan in
Grayscale mode.
• For full-color images, such as photographs or illustrations, scan in
Color mode.
• For example, with OCR applications using Black and White scan
mode, more than 300 dpi is the recommended scan resolution.

Optical and Enhanced Resolutions
Optical resolution refers to the amount of information a scanner can sample
per inch. Different varieties of scanner feature different optical resolutions.
The maximum optical resolution of the CanoScan FB1200S is 1200 dpi for
both the primary scan (horizontal dimension of the document) and secondary
scan (vertical dimension).
The 1200 dpi resolution of the primary scan is achieved with a proprietary
Canon technology, the VAriable Refraction Optical System (VAROS). VAROS is
a two-pass scanning technique that combines the results of the scanning
unit's first pass with a second pass that is optically shifted by a half pixel. This
technique is used for scans at resolutions of 601 dpi or greater.
Estimating Image Sizes
When scanning many files, you have to consider the available space on your
hard disk and weigh it against how you plan to use the images.
High - resolution, color image files take longer to scan. If you have less than
32 MB of RAM, working with large color image will be very time consuming.
Consult your imaging application’s documentation for guidelines.
The output file size depends on the image resolution, scan mode (Color,
Grayscale, or Black and White), and output dimensions. Lower resolutions
contain a fewer number of dots per inch, and therefore less digital information
to store on disk. So, when estimating the size of an image, you have to include
the output file size, the resolution, and the number of colors.
Resolution and Color
The greatest amount of disk space is required for a 36-bit Color image of one
horizontal inch, centimeter, or pixel. Each pixel contains 24 bits of color
information: 8 bits each of red, green, and blue, and 36 bits of color
information are required for a 36-bit Color image. Resolution refers to the
number of pixels per inch, or in printing terms, dots per inch (dpi).
Check the ScanGear CS-S status area for the estimated file size of the acquired
image. Generally, file sizes can range from 15 KB for a 6 inches x 4 inches image
scanned in Black and White mode at 75 dpi to 202,500KB(198 MB) for the same 6
inches x 4 inches image scanned in 36-bit Color mode at 1200 dpi.

Cropping the Image Shape
In most cases, you will want to crop the preview image before your final scan,
to eliminate white space or other unwanted images from the final product. By
combining the use of the Crop and Zoom tools, you can easily select a precise
section of the image, and then make other changes.
The Crop tool lets you select a rectangle shape of the preview image. You can
switch between the Crop tool and the Zoom tool to select exactly the part of
the image you want acquired.
If you select pixels as the unit of measure, you can see the exact size of your
selection on the rulers in the preview area.
Use the selection handle to
move a side or corner of the
selection rectangle more
precisely
To zoom and crop the preview image:
1. Preview the image as described in Chapter 3, “Scanning.”
2. With the Crop tool, select part of the image. The selection is outlined with
a broken line. Handles appear at the corners and midpoints of the
selection rectangle, and the cursor changes to a selection
crosshair.
You can move the entire selection rectangle around, or you can adjust any
edge or corner of the rectangle by moving one of its handles. When you
place the cursor over a handle, it turns to a double-headed arrow, and you
can drag that side in, out, up, or down to increase or decrease the
selection rectangle more precisely.

3. Click the Zoom tool and zoom in on the image. When you select the Zoom
tool, the cursor changes to a magnifying glass.
The plus and minus signs on the mouse indicate that you can
enlarge the image (zoom in) by clicking the left mouse button,
and zoom out by clicking the right mouse button.
By zooming in on the image even more, you can select a more precise part
of the image to scan or work with.
4. Continue alternating between the selection and other tools on the
ScanGear CS-S toolbar as long as you do not click off the selection with
the Crop tool.
Custom Tone Adjustments
The settings on the Tone tab let you make individual adjustments to a variety
of tone settings.
What Do Those Curves Mean?
The curve displayed on the Tone tab represents the values of the preview
image according to the tone tool you are using. You may see multiple curves
of red, blue, and green, depending on the settings on the Tone tab, the color
mode, and the image.
The shape of the curve changes to reflect the current settings of the
Automatic, Contrast/Brightness, Gamma, and Histogram tone tools. You
cannot edit the curve except with the Special Tone Curves tool.
Contrast and Brightness Adjustments
The Contrast/Brightness tools control use the image’s brightest and darkest
tones for its reference in adjusting the overall image in a uniform way.
If you increase an image’s brightness by 10 percent, even the bright parts are
increased by 10 percent. So, if you are scanning an overly dark image with a
wide range of tones, increasing the brightness makes the dark tones more
visible, but the brighter parts may appear faded and washed out.
The contrast control bases its calculations on the image’s dark and light tones
to calculate an overall adjustment. Because the adjustment affects the lightest
and darkest tones, increasing the contrast increases the proportion of bright
and dark tones in the entire image. Decreasing the contrast lessens the
proportion of bright and dark tones in the entire image. This can give the
image a dull, washed-out look.

If you have a high-contrast image, or a black and white continuous tone
photograph that needs minor adjustment, the brightness and contrast
settings can improve the image.
If you have an image with multiple tones, such as most color images, the
brightness and contrast settings may not provide the desired results. The
Gamma, Histogram, and Special Tone Curves, which let you adjust the
midtone range and contrast as well as individual color ranges, may give you
more satisfying results.
Gamma Adjustments
The Gamma curve tool adjusts the midtones in an image in relation to
themselves. Adjusting the gamma setting can improve the visibility of color
and grayscale images, particularly ones with many midtones. Gamma values
above 1.00 lighten the midtones of an image, and values below 1.00 darken
the midtones. The gamma settings can range from 0.10 and 10.00, but for
most color photographs, the range is between 1.00 and 2.00. The
photographs scanned for the illustrations in this manual had many dark
midtones in the background, so a lower setting was used to enhance the
background.
Histogram Techniques
The histogram displays a graph of all the pixels in the image, sorted by tone.
The darkest pixels are grouped to the left, the midtone pixels in the middle,
and lightest tone pixels to the right. The triangular sliders at the bottom of the
histogram reflect the default settings of Black-Point 0, Mid-point 128, and
White-point 255.
The histogram tools let you change the distribution of dark-tone, midtone,
and white-tone pixels in your image, to correct the image. Any changes you
make are immediately displayed in the preview image.

The following preview image has too dark a background, probably because
the photograph was exposed to set off the white flowers more effectively.
The histogram for this image shows that most of the pixels are between the
black and gray points, so there are too many dark pixels in the image. The
diagonal line indicates the color channel, in this case, the Master channel.
The following figure shows just the histogram of the same image, but with
the blue channel, the predominant color in the image, selected. Notice that
the blue pixels are more evenly spread around the midtones, but there is still a
large distribution of pixels in the dark-tone area.

The following figure displays the histogram when the flower is cropped.
Notice the pixels are spread more evenly, although still leaning to the darker
side of the midtones.
You can adjust the histogram so the pixels are spread move evenly throughout
the range of tones in the image. The procedures for adjusting the histogram
are in “Change Tone Using the Histogram Tool” in Chapter 3, “Scanning.”
The easiest way to affect the redistribution of pixels is to adjust the triangles
at the bottom of the histogram. When you move the Mid-point slider to the
left, a larger number of pixels fall into the midpoint range, and more midtone
shades become visible.
Move the triangles to
adjust the pixel
distribution in the
preview image.

You can also achieve some special effects by manipulating the Black-point,
Mid-point, and White-point values to the extreme. In the following figure, the
Mid-point has been moved to the right of the White-point, producing a
solarizing effect to the lighter areas of the image.
Although the Special Tone Curves provide the best facility for manipulating an
image for special effects, you can experiment with any of the tone tools.
Sampling a Tone for the Histogram
To sample a tone for the histogram, zoom in as close as possible and sample
the black point, midpoint, and white point from an enlarged section, to make
sure you are sampling the shading you want. This is especially important
when you are adjusting an image with many dark tones and midtones, and it
may be difficult to determine the darkest or brightest spot with the naked
eye.
If necessary, select a section from which to sample, and re-preview the image,
then select the sample.
To sample a tone for the Histogram:
1. Zoom in on the area of the image from which you want to take a sample.
2. Using the Crop tool, select an area of the zoomed-in image from which to
take the sample.
3. Click Preview to re-preview the image. The preview image displays only the
selected, enlarged area.
4. On the Tone tab, select the Eyedropper tool for the Black-point, Mid-point,
or White-point values.

5. Click the Eyedropper tool on the point of the image you want to sample.
That value is entered in the corresponding text box, and the image adjusts
according to that value.
6. If the area of the image surrounding the sampled area changes tone as
you expected, make a note of the settings. If the selected image area does
not change tone as you expected, repeat this process until you get the
results you want.
Enhancing Color Images
This is a brief discussion about color basics. There are many good books about
working with graphic images. If you are using color imaging software such as
Adobe Photoshop LE, your software documentation can provide you with
more information to help you adjust your images when they have been
scanned and acquired by the imaging software.
About Image Color and Color Channels
All printable colors can be created using a combination of the colors cyan,
magenta, and yellow (CMY). (Black is often used in printing, so you may hear
that colors are printed using the “colors” CMYK, the K stands for “Key
color.”)
All colors displayed on monitors can be created using a combination of the
colors red, green, and blue (RGB). Red, green, and blue can be thought of as
complementary colors to cyan, magenta, and yellow-that is, the colors cancel
each other out when combined in equal amounts. Similarly, adding a small
amount of one color reduces its complement by that amount.
This complementary relationship between the colors cyan, magenta, and
yellow and the colors red, green, and blue can be represented using a color
wheel that indicates the possible colors and their opposites.
Green
Yellow
Cyan
Red
Blue
Magenta

Using this color wheel model, you can use the Tone tab adjustments to modify
specific colors and correct the preview image before scanning. You can select
the Red, Green, or Blue channels and adjust the Gamma, Custom Curve, and
Histogram settings for the image, to provide the results you want.
For example, if your original picture has too much yellow, you can adjust the
color by increasing its complement (more blue). If the image has too much
green, you can increase the combination of colors to decrease the magenta.
Note:
If you are working with images that are meant for
professional color printing, all your equipment should be
calibrated so the color values on your scanner, monitor, and
output devices are using the same frame of reference. This
means you should make sure you have a video monitor that
can display Full Color (24-bit), up to 16.7 million colors.

Pre-Scan Checklist
Before you begin troubleshooting specific problems, verify that you have
reviewed this checklist.
• Viewing that your system meets all the memory, hard disk and
operating system requirements listed “System Requirements” in
Chapter 1.
• Make sure that the ScanGear CS-S software was installed
successfully.
• Check that the cables between your computer and scanner are
connected securely.
• If you see a message on the screen that says something like this:
“Device failed/cannot find TWAIN...” make sure you have turned on
your scanner first, before your PC. If necessary, turn the scanner off
and back on again.
• Turn on your scanner before you turn on the computer.
• Before scanning or previewing, check that the data source has been
selected. If your scanner does not appear as an option when you
select a source to scan from your imaging software, you may have
to install ScanGear CS-S again.

“Top Ten” List
Here is a list of the “Top Ten” pieces of advice for scanning.
1. Start with the best possible original image to scan.
2. Select only the part of the image you want to scan. Preview the image and
select it. Not only does a more precise selection save file space, but your
image quality will be much higher.
3. Check the output file size before beginning the scan. Make sure you have
enough room if you are scanning files that take up a lot of disk space.
4. Match your Scan Mode to the output purpose. If you are scanning text,
use the Text Enhanced mode. If you are scanning line art, use the Black
and White setting, and so on.
5. Match your scan resolution to the type of file you need. If you are
scanning images for use as .GIF or .JPG files on the Web, you do not have
to scan at 600 dpi. Although it is recommended that you scan at a higher
resolution than you need for high-quality color images, you should balance
that factor against your planned use for the image.
6. Take advantage of the Gamma tone curve and other tone tools to correct
your images.
7. Try to use Full Color mode on your monitor so you can view your preview
image as accurately as possible.
8. If you are using OCR software, scan in Text Enhanced at 300 dpi or higher.
9. If creating halftones, scan at twice the halftone resolution.
10.Take advantage of the preview feature and preview as much as you want
before scanning.

Printing or scanning is too slow.
Problem:
The printer or scanner is taking an unusually long time to
print or scan.
Cause:
The selected output resolution of the image may be too
high for the resolution of your printer, or your computer
may be low on memory.
Solution:
Before printing the image, make sure you have set the
scan resolution (on the Main tab) to not exceed the
resolution of your printer. Also check to see if there is
enough memory available in your computer. Before
printing, quit other applications that are not in use.
