Last night, I made the mistake of putting some 3-in-1 oil (yes, I know, it's not a good lubricant) in the bushings around the teflon roller (that the heater lamp runs through) in my Laserjet II when I disassembled the fuser to replace a worn 14-tooth gear. I should have done a more thorough disassembly and used grease rated for use with high temperatures... anyway, what concerns me is the low flash point for the 3-in-1 (if what's in the can I used is the same as the spray; the spray is all I could find data for, flash point about 101 degrees F). When the printer warms up for a few seconds, there's some smoke. I was thinking that it might just smoke a bit and then eventually stop smoking, but I remember, all too well, the time I accidentally spilled some motor oil on a hot exhaust manifold when I stopped at a service station on the way to pick up my PDP-11/73 system years ago... fortunately a rag was able to be used to put out the flames, and I do mean big bright yellow flames, quickly before any damage was done. Is this 3-in-1 oil likely to do the same thing in the fuser assembly? If it wasn't raining outside, I'd be tempted to put said oil on an old fuser assembly with a scratched up roller, with all useable parts removed, take it outside, apply power to it, and see what happens. -- Copyright (C) 2003 R.
