What do you guys think this is that was stuck to the UFR?
This is right after I started cleaning it off. The liquid on it is the WD-40 I was using to clean it.

It turned a milk-chocolate brown color as it dissolved and would flake off with some gentle scratching with my thumb nail.

It cleaned up nicely but I don't know why this substance stuck to it. This fuser unit only has 10k on it and the UFR doesn't look worn out.
