Salvaging HP Laser Jet series II

[Jim Isbell]

Well, with the help from members of this list I finally got one Series 
II running and one not tested but saved back and two that were FUBAR. 
 So, because I cannot bear to throw anything away all at once, kind of 
like the story of the three legged pig, i decided to scavenge what I 
could of the two Series II before pitching them.  I just pitched the 
Series I, the 3, and the 4.  

I saved anything that had a wire connected to it and put all the 
plastic, sheet metal and gear trains into the trash on the theory that 
the gear trains looked tough enough to not be a failure point.  I saved 
about half the weight and half the storage space.

The fuser bulbs looked to be in good shape so I don't think they were 
the cause of the "50 Service" error I was getting. At least the 
filaments were not broken.  I am assuming that this is like a halogen 
bulb and you don't want to touch the glass surface of the bulb.  

Is there a recommended cleaning procedure???

Too bad the fans are 24 volt not 115 volt.  I could have used some 115 
volt fans for my Kilowatt Linear I am building.

Are there any parts I missed?  Are there some parts I should have dumped?
