A:
It's actually very easy with this stamper. Holding the handle towards the floor, push the movable part towards the handle. Then press the small red button to lock the movable part in place. You will be able to see the ink pad clearly. Flip it around and you can then pull out the old ink pad and insert the new ink pad. To unlock the movable part, simply press it towards the handle again and it should unlock back into it's usual form.
It is also easy to do it this way if you just purchase the blue and red ink containers rather than a whole new ink pad. Then you just add a little ink to necessary areas and you are good to go.
