Here's one that might help you not fall down the rabbit hole.
Tech dispatched to a "wrinkles" call on an 8518. on letter, the upper left corner was a sharp fold, print was in the fold
So it pretty much has to be POST image transfer. Tech noticed some wrinkles on the fuser belt, so he had another fuser
to swap it with. After about 10-20 copies, pretty much identical wrinkles. So, going down the "rabbit hole" he ignores
the fuser, since it was a rebuilt one and starts looking for other issues.
After spending time, he gives up, had the supervisor look at the machine. Hearing what he had already done, he went a
different route, couldn't find anything.
Machine was brought to the shop and he and I started looking for things. But I still say it had to be fuser because the image
was in the fold area. He said but the fuser was replaced. I said lets try one from a demo machine. The problem disappeared.
Placing the fuser on my workbench, couldn't really find anything until I flipped it upside down. That's when I found this.

Entrance guide, 6LK42418000 Guide-Ent-PR-H38X had several of the guide fingers broken.
Called the tech, he brought me the fuser that was in the machine when this started, and it looked like this.

Pretty much the same thing. As I always say, just because you replaced something, doesn't always mean it will
fix it, just because it is new.
I've only seen this 2 times, both were 8518's that already had the fuser mods & temperature changes, so other than
just "bad plastic" I don't think they were damaged sitting on a shelf, especially since the original fuser was still in this
8518.
Just passing along...
