A NOTE ABOUT TWAIN
-----------------------------------

Since the TWAIN standard is being updated on a regular basis, and
software application companies try to address these changes, you
may occasionally experience some minor problems caused by
applications that are not fully TWAIN compliant.  Canon works
closely with software manufacturers on compatibility issues to
ensure user's a trouble-free experience.
