Hi, MikeS
It is good to see you again at FineTunedMac!
If you need more help in working through the Canon Pixma MP630 printer/scanner/etc problems, let me know in a reply here.
If so, I will split this troubleshooting branch from the "Migrating from PPC to new macmini" topic and create a new topic for you in the "Peripherals" forum which provides help with scanners/printing, etc.
Please do not worry about posting your problems and questions at FineTunedMac.
Moderators and members are dedicated to helping those with questions find good answers.
