Question about Canon i-SENSYS LBP631Cw

So I'll just ask now, otherwise I'll send the junk back: Everything is set up, everything is displayed correctly, but when you print something out, the printer makes a beep and the printout ends up in nirvana. It's embarrassing, this is the 4th laser printer since 1994 and the only one that doesn't work straight away. So if no one has any ideas, the junk will go back tomorrow, I can make fun of myself....
