Firstly, no guarantees, install Synaptic Package Manager from Software. Launch Synaptic (you will be asked for your login password to elevate you to 'root') and search for 'skanlite'. I recommend this based on my recent experience with other OS as it is the first app that works with our Canon LiDE 500F which has never worked under GNU/Linux until now. The only other option you have is a commercial product I own, is VueScan from here:
Lastly, does the Canon website offer ScangearMP package? If not VueScan might be your best option and it certainly has a better interface than Canon's ScangearMP.
I own the Pro version, it is brilliant and multipage scans donct require the preview to be run once first page has been scanned.
