8518 wrinkles

[Rusty.Harris]

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...

Tech AND the Supervisor missed this, and you had to bring the machine back to the shop.......?
Time to clonk a few heads together like the 3 Stooges.
Thanks for the info.

Some time ago I worked lastly on E-studio 850 and believe 8518 is something similar maybe with more plastic but still heavy office machine. With my back headaches I would be damn sure this is on me to move machine to the shop. I mean how many times basics are wrong and how many times wrinkled paper is not coming from fuser problem. Letter-R can unveil some more etc.

I would keep an eye out for a behavior issue with that customer.

IIRC, this fuser removes with only the two thumb releases, so it's fully possible that the enduser is removing paper jams by pulling the fuser, clunking it down on the counter (and breaking off fins), then re-installing the fuser. I've caught a couple of endusers doing this on similar models. It's also possible that the re-build tech doesn't know he's doing it. Just a suggestion. =^..^=

I forgot to mention, it did it on letter-r and all trays.

I thought about this, but it is a school and I think most of the users are women, which I couldn't see them removing the fuser.
But, they may have a "Rosie the Riveter" one.

Yep, was about to mention this possibility. Easy to break those while you pull out the fuser. They snap really easy under prolonged heat treatment.

Then design is a problem. Must be replaced not rebuilt. Gently touching baked plastic is enough.
