zippi, admitedly dh usually does it, but I have been known to! the trick is to lay the bits out in order so you know which bit goes where. and not to let the cat into the room where you've laid the bits out!
it's usually the little rollers that pull the paper though that go, or the bits near the ink jets get clogged up with ink. you could have a go at cleaning those bits with switch cleaner and cotton buds if you're too chicken to take it to bits!
I am on a crusade to stop so many things being thrown away - can you tell?
