It took me a while to get my canon scanner working under Lion. The trick is that there are two programs that you need to install – the scanner program and the driver. This works for Leopard and Snow Leopard too.You need to install the canon toolbox which is the general canon scanning program called “CanoScan Toolbox Ver. 220.127.116.11X (Mac OS X)” but you also need to install the ‘driver’ for your particular printer (for my printer it was called “LiDE 60 Scanner Driver Ver. 18.104.22.168X (Mac OS X)”. There’s no where I could see on the canon page that tells you you need to download BOTH these files.
I found both these by going to the canon page here, and typing in ‘LIDE 60’ Then I got a list of options, and I chose the link under my printer ‘CanoScan LiDE 60’ which took me here. I clicked drivers and downloads which took me here. Both the files were there in the list. Install the toolbox first, then the driver, then you’ll need to restart.
It then gave me an error as follows:
“The system extension â€œ/System/Library/Extensions/CNQL1212_ClassicNotSeize.kextâ€ was installed improperly and cannot be used.”
This is apparently an old file Canon forgot to remove. Remove it manually from, here:
