If you measure values in the indicated range on the right hand side of the fuser, the lamp is fine (240V fusers will read 3-4 times higher on the right hand side).
Models HP LaserJet 4V/4MV (Check uur cross reference guide below for other brands)
Removal Instructions Open the front of the printer. Pop out the charge transfer roller, being careful not to touch the surface of the roller. Handle it at the metal ends only. Remove the 5 big brass screws holding the fuser in. There is a screw at each lower end of the fuser. At the top of the fuser, you'll see 5 screws. Remove the 2 outboard and the center screws. While pulling out on the plastic side to clear the metal shaft, lift one end of the fuser up, repeating for the other end.
If you don't have a meter, continuity can also be checked across the contacts on the right hand side of the fuser by using a digital tester.
