LaserJet 8000 series printer fuser - ghosting
I have a number of LaserJet 5Si/8000/8100/8150s here in the company I work for.
Now, a problem that seems to spring up quite often (more often than it should, in my opinion) is that the middle of the upper fuser roller gets what seems to be layer upon layer of toner torched onto it. The stuff is unbearable to try to scrape off, and requires about a 6-hour cool down period before I can try to scrape the stuff off, but that knocks a printer out of commission for the better part of a whole work day. And the things are bloody expensive - upwards from $300 a pop. So I only like to replace them when they're absolutely burned out.
My question is, if anyone else has a similar problem, what do you use to clean the roller? I've tried dry towels and scraping with my fingernails, damp towels, and even isopropyl. But nothing seems to loosen this stuff up! Is there a special cleaning fluid for printer parts like this that are good for taking off baked-on toner from an upper fuser roller?

All good help, guys - sorry about not returning to this earlier.
I'm going to replace the ones in question and keep the others around instead of return them for the core charge right away. I'll try some litho cleaner as wylie suggested, as well as a fuser rebuilt as suggested by joe, and see if one of them isn't more cost-effective as replacing the whole assembly in the long term. Thanks.

The toners are almost always third party hear, much to my chagrin.
Printing the blank pages doesn't seem to do much, aside from wasting paper. The toner stays on the fuser roller, like it's physically baked on there.
Neither of the fusers in question have nearly 350,000 prints on them. That's why I'm starting to wonder about this. I'm really thinking that the cheap toners probably has something to do with it...
Replacing just the rollers... I didn't know this could be done! Perhaps I'll try it next time around.
I'll tinker with it and let you guys know if I can figure anything else.
