How long does it take to install the maintenance kit completely on an HP LaserJet 4000 TN printer?

Here is a link to instructions http://www.printertechs.com/tech/mkinst/mk-4000-1.php If it's the first time you've installed a maintenance kit on a laserjet 4000 I would guess betweein 30 - 45 minutes.
