Answer
Looks like you can fire the cannons.

The Canon you noted looks OK but I've also used an 8 or more megapixel camera for such scans. Let's try a little math to see if 8MP is enough?

A4 paper size is at http://en.wikipedia.org/wiki/Paper_size

So if I take my old 8MP 3264x2448 pixel camera and take the 11.7 inch side along the 3264 side, I get the following DPI.

11.7 inch at 278 DPI
8.3 inch at 294 DPI

Since a lot of phones have 8MP cameras and this quality is about double of a fax copy, why are you getting a scanner if these are just notes?

I don't have a proffesional camera but I have the camera in my phone (galaxy s3).One of the main reasons, I want to buy it is the ADF (The lecturer writes a lot so I need to scan every week a full pad of 40 pages) . Additionally, the pictures in the phone are crooked and that's a long seperate process of uniting them into one PDF. Thanks for help but for the time being I still want to buy a scanner.

You are basicly right but..

Besides my hands are realy shaky, that seems a long sisyphean process which may take around 10minues per lecture. Needless to say that with a scanner it take few minuets. I'm very sorry but I haven't been convinced yet...

Why I brought it up.

Folk have bought such and then ask me how I do such things. I'm sharing an alternative along with the math to back it up. On top of that I shared a free app for that.

Only shared my way just in case you wanted to try it.
