Xerox Laser Printer parts (was RE: non-existence of printer collectors...proven wrong)

This recent talk of LaserWriters has reminded me of the Xerox 8812 printer that I have in the garage. It's only about 10-12 years old and so just barely qualifies as "classic", but I actually want to _use_ it :-) You see, it's a B-sized laser printer and it's great for printing schematics or 8-1/2x11 pages "two up" in landscape mode. It became unreliable when age turned several of the rubber paper feed rollers and drive belts into sticky goo. None of the printer parts places seem to list the 8812 any more, so even though it's barely "classic" it's apparently "obsolete". I hate to trash it - new laser printers are really cheap these days, but true B sized printers are still pricey. Besides, I've still got a brand new, unopened, toner cartridge for it that I have to use up :-) Can anybody suggest a source for parts? Thanks, Bob Armstrong
