Hi Rich J, Keith & David McCann.
Thanks for all your replies, as I'm new to Linux Forums not sure which is correct way to reply so hop[e this way is okay.
The method put forward by Rich I didn't think had worked however, I tried it again after restarting my computer and pleased to report that I am able to connect to the Canon scanner with Simple Scan exactly as I was wanting to do. So thanks again for all your help.
