HP LaserJet 4000/4100 Both the LaserJet 4000 and 4100 look the same but many of the parts are in fact different. The fusers and maintenance kits are different. The HP LaserJet 4000 fuser is screwed in the back with self tapping screws which is a poor design because the plastic housing can get stripped - use caution when tightening the screws.
