[HP Printer fuser]

  These parts are available, but expect to pay $30
to $50 each for a new lamp
 and tube.  The job is not that difficult if you know what you are doing, but
 substantially more difficult if you don't (big surprise, right?). 
I don;t know what I'm doing, but I've stripped and rebuilt the fusers for 
the CX and SX engines. The most important thing to remember is that the 
'heater' is a quartz-halogen lamp, and you must not touch the 'glass' 
with your fingners. The CX one is difficult to handle (it's possible to 
hld it -- just -- by the ceramic end cap), the SX one can be handled by 
the wires.

 Hi
 I thought I'd mention that should you actually touch the
quartz part, it is not throw away yet. You just need to
clean the surface well. Rubbing alcohol works well at removing
finger grease but I always like to follow with a good dry
cleaning fluid like automotive "Brake Clean".
 What happens is that your finger grease will carbonize
on the hot surface and cause a hot spot. This will stress
the quartz tube and break it.
