How do I Batch Scan using Canon Pixma G2010

Upon researching I got to know about a very useful utility in Windows OS, called "MouseKeys".
Here is how to use it,

1. Press (Left) Alt + (Left) Shift + (Right) NumLock
2. Choose Yes
3. Now on your numeric keypad 8 simulates up, 6 simulates right, 4 simulates left and 5 simulates click action of a mouse pointer.
4. Now you may hover your mouse on the scan button and simply press 5 to get it started.
