HP 4+ Never seen this before!!
I haven't seen it personally but I've heard about it a few times. A tech once emailed me and told me that the lower pressure roller was filled with silicon oil and it leaked out. He claimed to have seen the problem numerous times. Strange that I've worked on hundreds of them and never seen it once? I cut open a couple of rollers that we'd changed during fuser rebuilds and found them all dry. The liquid is an illusion, it's really only an air bubble. I can't comment on the oil spots since I have no idea where it's coming from. I'd try and stop the paper just as it hits the fuser, pull it out and see if it's happening before. Those fusers, especially the cheap rebuilds have toner buildup problems in the center area, perhaps you are mistaking that for the stains. It's hard to diagnose when I'm not seeing it. Of course if I had it in the shop, first thing I'd do is pull a fuser off the shelf and try it. Ours are quality rebuilt. We use OEM Canon upper and lower rollers, not the cheap 3rd party stuff that lasts 6 months. Hope this helps.
