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 Adobe Photoshop LE, 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.
