[Misc] Fuser oil on print outs - Aficio CL7100

[chrisio]

Hi.

Well after getting my dodgy prints sorted out I now have another problem in that I have a touch of fuser oil bleading onto the leading edge of any prints, it is tiny but its there.

We bought this printer second hand of eBay and the fuser unit was packed seperatly but we think its been tipped in transit and got oil where it shouldnt have. The problem seems to be worse when running a duplex run and on single sided it is 99% clear, is it a case of running it until its clear or is there something I can clean (I have ran a ream of paper through it today and its better but still there).

I have stripped my spare fuser down following the service manual (it was broken anyway causing jams etc so I wasnt bothered about breaking this one) but I am nervous about doing this to my decent one as I couldn't really see anything in there that could be causing it to put such a tiny smige of oil on the edge.

Over to you guys.

Thanks
Chris

Clean off the lower paper separation claws, they collect oil and paper dust and lead to the oil marks on the copy.

Oil spotting was a known issue on this machine. Cleaning the sep claws will get you some relief, but more than likely the issue will return. You can try a fresh fuser or I've had some luck with thicker paper types as the oil doesn't permeate as deeply. Good luck with it.

Thanks for your help both of you.

Again - showing my ignorance but can you point me in the direction of the lower paper seperation claws please.

Cheers

Well, I 'think' I have resolved this..

I found what I think were the paper seperation claws on the back side of the fuser and they were covered in a coating of paper dust and oil.

Cleaned them as best as I could without dismatling anything and the prints are now perfect.

Thanks again for your help

Sorry to drag this to the top.

But the oiling problem is back again and I think its because I didnt clean the seperation claws well enough.

What sort of solvent can I use near the fuser that will not damage anything and is it safe to use a cotton bud in there without damaging anything.

(ideally we really should replace the fuser unit but the fuser unit costs 4 times as much as we paid for the machine and other than this small problem its running well.)
