How to Use this Guide
This guide explains the operating procedures for Canon Plug-in Module CS-U
(hereafter referred to as Plug-in Module CS-U), the Macintosh driver (plug-in
software) used with Canon image scanners.
A plug-in is not an independent software program; it must be used within a plug-in
compliant application, such as CanoScan Toolbox or ArcSoft PhotoStudio 2000, to
expand the capabilities of that program. Adding scanning capabilities to your
computer is as easy as putting in a plug. Simply copy the Plug-in Module CS-U files
to your computer.
Please read this guide to perform the installation procedures and scan. Store this
manual in a handy location for future reference.

Plug-in Module CS-U Special Features
• See the Results of Adjustments Immediately (Dynamic Preview)
Once in preview mode, the results of adjustments to scan mode settings and colors
are promptly reflected in the preview image.
Highly detailed adjustments can be performed easily because you can see the
results of your changes as they are executed.
• ColorSync™ (Ver 2.0 +) Compatible for Auto Tone Correction
Compatible with the Mac OS 8.5 ColorSync™ (Ver 2.0 +) color management
software. This function automatically matches the color profiles of various devices,
such as scanners, color displays and color printers, for optimal color reproduction.
• Browser Function Permits Confirmation of the Real Image
Before Scanning
The Browser function lets you check the image to be scanned in detail before
commencing the scan. This function presents a much higher quality image than the
preview function.
• Histogram Function Realizes Beautiful Contrast
Simple operation allows you to achieve beautiful contrast with half-tone
gradations.
• Gamma Curve Adjusts Image Brightness
The Gamma Curve feature provides four methods you can use to refine in detail
the level of image brightness until you are satisfied with the results.

Operating Procedures
The following provides an example of scanning from within ArcSoft PhotoStudio
2000.
Verify that the scanner is attached to your computer and that the power
is on.
Read the Getting Started guide for instructions on how to connect the scanner.
Start ArcSoft PhotoStudio 2000.
Select Plug-in Module CS-U from within ArcSoft PhotoStudio 2000.
Open the [File] menu, select [Acquire] and [CanonPI CS-U 4.0.0...].
The Plug-in Module CS-U control panel will display.
Caution
• Plug-in Module CS-U is not a stand-alone application program. It must be
started from a plug-in compatible application program, such as CanoScan
Toolbox or ArcSoft PhotoStudio 2000.
• The size of the Plug-in Module CS-U control panel will vary according to
the resolution of the computer display.
• The size of the control panel can be adjusted with the [Preview
Window...] option in the [Preferences] menu (p. 26).

Positioning Originals
Place the original you intend to scan on the scanner's document glass (platen).
Procedures
Place the original on the scanner's document glass.
Open the cover and set the original face down on the scanner’s document glass
with the top edge at the front of the scanner. Align the original’s corner with the
alignment mark.
Close the cover carefully so the original does not shift out of position.
Caution
• Be careful not to dirty the document glass when placing items on it.
• If an original has distinct horizontal or vertical lines, you should try to
position it on the document glass as squarely as possible to have the lines
appear straight.
• The maximum scanable size is the area of the entire document glass.
• Straighten out curls or folds in originals before placing them on the
document glass.
• To scan right to the edges of an item, position it approximately 2 mm
away from the edges of the document glass (platen).

Previewing
The preview scan is a trial scan performed before the final scan that encompasses
the entire scanable area of the document glass. The preview image is shown in the
preview window. Use this image to specify a scan area and adjust the scan settings
for the image.
Operating Procedures
Click on the [Preview] button.
• The image will be scanned and appear in the preview window.
Hint
• To change the size of the preview window, use the [Window Size] settings
in the Preview Window Settings dialog (p. 26).
Caution
• The Dynamic Preview function enables changes to settings, such as the
scan mode and brightness, to be immediately reflected in the preview
image.
• Nevertheless, the preview image provides only an approximation of the
scan and the final results may differ to some degree from it.
• Calibration automatically starts when [Preview] or [Scan] button is clicked.
Do not lift the document cover while calibration is in process.
➟
When the amount of light of the lamp inside the scanner is insufficient, the
message “Now adjusting lamp…” may be displayed. Wait as is, until the
amount of light increases enough. If you click the [Cancel] button in this
dialog, the preview scan will be executed with insufficient amount of light, and
the previewed image will not have the correct color balance. Click the [Cancel]
button only if you need to obtain the previewed image quickly although
without the correct color balance, before the amount of light is sufficient.

Selecting the Output Device
Use the following procedures to select the output device (printer, etc.) for the
scanned image. Select the device that corresponds best to your output device and
use of the image.
Operating Procedures
Click the arrow on the [Output Device] section of the control panel and
select a device from the pop-up menu.
Caution
• You can set the device categories in the pop-up menu in advance. You can
also add new devices to the pop-up menu. See Setting Preferences (p. 25).

S T E P 1
Setting the Resolution and Magnification
The magnification of an image can be changed before scanning to accommodate
reproductions that are larger or smaller than the original. The settings can be
changed in increments of 1%.
Changing the magnification setting causes the resolution display on the control
panel to change correspondingly. This resolution setting is referred to as the
“scanning resolution.”
Output Device Resolution= 720 dpi, Magnification= 100%

Hint
Magnification and Resolution
Why does the image size change with the magnification? Let us answer this
with an example using a “BJ (720 dpi)” output device. If you were to scan
an image with this device setting and set the magnification factor to 50%,
the scanning resolution will automatically change to 360 dpi. At this
setting, the image will be scanned at a resolution of 360 dpi and the output
device will convert this to 720 dpi, shrinking the size of the output in the
process because it will only have half the data with which to fill the space.
20
S T E P 1
To Set the Magnification Factor
Set the desired magnification factor on the control panel.
Hint
The Relationship Between Data Volume and Scanning Resolution
The higher the magnification and scanning resolution settings, the greater
the file size of scanned images. There are certain inconveniences associated
with large data volumes, such as longer processing times and the risk of
running out of memory resources. You are advised against setting the
resolution higher than necessary. For example, if you scan an A4 (21.0 x 29.7
cm (8.3 x 11.7 in.)) size image in the color mode, the amount of data varies
according to the resolution.

S T E P 1
Setting the Scan Mode
When an image is scanned, it is read as a collection of “dots.” The scan mode that
is selected determines how each of these dots is represented in the output. The
following four scan modes are available.
Black and White
Expresses images in two colors only: black or white. A dot is expressed as either
black or white according to its brightness level and the value set as the threshold
value, which can be freely set. Select this mode to output to a monochrome
printer.
Grayscale
Expresses images in 256 shades of gray. Select this mode to scan black and white
photographs or create monochrome images from color images.
Color
Expresses each color channel (RGB) in 256 shades (8 bit). Select this mode to scan
standard color photographs.
Hint
Scanning the same image in the four different scan modes produces
different file sizes. By size, black and white mode requires the least disk
space, followed in order by the grayscale and the color modes. Before
scanning, check the data volume indicated on the control panel.
The numerator indicates the amount of
disk space required for the scanned image
while the denominator indicates the
amount of disk space available. When the
required space exceeds the available
space, the scan button is unavailable.
