Question : Problem: Hard Reset procedure for LaserJet 4600dn?

Hi all!

Anybody know the Hard Reset procedure for a HP Laserjet 4600?  I've been Googling for the past hour or so and keep getting hits where people suggest it (eg: "Have you tried a hard reset?"), but nobody has mentioned the exact procedure.  

I know on another LJ it has something to do with holding certain buttons down while you plug it in - but if you can help with the 4600 I'd appreciate it!

Thanks!

Mark
