Welcome to ScanGear CS-U 5.3
Welcome to Canon ScanGear CS-U 5.3 software for Windows 98.
ScanGear CS-U 5.3 (hereafter referred to ScanGear CS) will provide
flexible, efficient image enhancement tools for scanning with your
CanoScan FB630U/FB636U Scanner by providing an interface with
a wide variety of TWAIN-compliant software applications.
ScanGear CS has a number of powerful features that help you
achieve peak performance with your scanner. Using ScanGear CS,
you can preview and adjust an image before the image is scanned
and acquired by the target software application.
Here is a quick summary of the important features of ScanGear CS:
• Flexible, fully automatic image acquisition, and pre-scan
image manipulation prior to passing data to the image
application
• Sophisticated, Windows 98 user interface
• TWAIN 1.6 compliant
• High Definition Color
• Text Enhanced mode for OCR applications
• Canon ColorGear (Color Matching software technology)
• Automatic preview or preview image cache

Before You Begin
• ScanGear CS can run with or without its main window,
depending on the acquiring application.
Normally when you start a scanning job, you will see the ScanGear
CS main window with its toolbar, Preview Area, and tabs.
However, some software applications may not open the ScanGear
CS main window. When this occurs you cannot use the settings
described in this user’s guide because the parent software
application will provide the settings so you can change the image
after it is acquired. When a software application uses ScanGear CS
without opening the ScanGear CS main window, this is called the
windowless mode.

This is a quick overview of executing a scanning job. For more
information about detailed ScanGear CS settings, see Chapter 4
and Chapter 5.
Preparing the Scanner
Follow these simple guidelines to prepare for a scanning job:
• Before you start scanning, make sure the scanner is
connected correctly.
• Always position the original on the scanner platen with the
image side down.
• ScanGear CS lets you correct many undesirable features in
scanned images, but you will save time and effort by starting
with the best possible original. If you are scanning a
photograph, for example, make sure the original is in the
sharpest possible focus.
• If you are scanning text, make sure the printed text is sharp
and clean.
