You need backend version >= 1.0.24.

Your scanner is supported from the pixma backend! Ignore the canon*
backends.

Follow the step by step instructions in README.linux starting here:
'Step by step install on Linux 2.6.* and 3.*, both with udev:'.
Ignore the other stuff around.

You can skip position '3.2. Localization file:'.

Maybe you need to install some development packages first. But this
depends on your Linux distribution. What Linux distribution do you have?
