Get the file: mp640sosxcp102620ea8-2.dmg and install it.ħ) From the Printer's own panel, check its IP address from Settings > Lan settings etc. (don't worry if you got this far before - it just establishes whether the printer is technically 'there' wirelessly regardless of whether the Print Box can see it).Ħ) Download updated CUPS driver from Canon Site at: but also remove the Canon folder in the main Library > Application Support.ģ) Empty the Trash (restart if a few are 'in use' and then delete - they should go)Ĥ) Get your printer recognising your wireless network using the 'easy' option in the settings > wireless menu such that the printer at least reports 'connected OK.ĥ) Re-install software from CD - run thru' entire process as before and see if the Canon network utility can 'see' the printer and do a speed test on it. Nothing! - just the scanner aspect announcing under Bonjour, but no printer.ġ) reset the printer back to 'factory' from its settings menu.Ģ) DELETE all instances of Canon installed software for this machine (and any earlier models if you had them) - Use Spotlight to find them if necessary.

(MacPro - 10.6.2)ĭid all of the above, downloaded the various updates, patches, you name it. The following may help you - it solved the problem for me. Indeed, I almost didn't buy the MP640 for that very reason.
#CANON MP640 PRINTER DRIVER MAC FOR MAC#
Strange company, Canon I like their hardware (I've used a Canon scanner for some eight years and it has always been reliable), but they seem to have no idea about providing decent software support for Mac users.

Followed the downloads, did the installs, and She Who Must Be Obeyed can now print wirelessly from her Snow Leopard MacBook. Then, joy of joys, I found your feedback and links here. Left a message on the uncommonly clumsy and slow Canon Customer Support site. Visited some Canon sites and found updated drivers for Snow Leopard for the MP630 and for WIndows users of the MP640, but nothing for the combination MP640 and Snow Leopard. Bought an MP640 for its wifi capability and was able to set it up reasonably easily for use with my own PowerBook, under Leopard, but quite unable to get it to work with my wife's MacBook under Snow Leopard.
