Procrastination, it's my middle name

Ok I really need to not wait until 11 o'clock the night before a test to start studying! Anyways to procrastinate studying even more my lesson for today is: When changing the toner on a copy machine you don't actually take the whole thing out and put a new one in like you would on a printer; it's more of a transferring the contents of one thing to another thing type deal, and if it's done incorrectly I hear it's one of the messiest mistakes ever (not that I would know personally). So by all means read the instructions on the box or at least pay attention to the freaking tutorial that the copy machine itself will walk you through.
