bizhub PRESS C1060: where did this little guy come from?

I suppose it would be best to start at the beginning ...

Last week I ordered up the fuser rebuild. The parts showed up, and when I contacted the customer they said they were getting a quality issue, repeats at a long interval ... and to me, look suspiciously like a mustache. It could conceivably be the fuser belt, so off I go.

Of course it's not ... it's the primary transfer belt. There's an outward dent in the belt surface and another hole both centered on the belt at opposite poles. We have a very very very very worn transfer belt lying about ... the only thing going for it is that it has no dents or holes. that same belt got replaced a month ago for C4505 errors when color calibrating, so I don't have much hope for it.

I got the transfer unit cleaned & belt on. Now the fuser is only warm and I can start rebuilding. When I removed the fuser front cover out drops a capacitor. Hmmmm.

The only electronics in the front of the fuser is the fuser pressure motor, and I'm pretty sure it never had a capacitor, but there isn't any way to confirm that. Did I mention that the fuser still works, other than the bands in the feed direction of low-gloss?

Anyway, it boots to a C4505 like I expected, so now the transfer belt is on order.

On the way back I got to thinking: I think the transfer drive motor has a capacitor (or had a capacitor ... I would look if I was still there). Regardless of where it started out, I believe it was the capacitor tumbling around in the transfer belt that made the defects, then it dropped out into the top of the fuser cover.

Interestingly, that capacitor doesn't seem to be necessary. Transfer and fuser pressure motor run fine. I'll be sure when I get a decent transfer belt on there.

So where do you suppose this little guy came from? =^..^=

Maybe a cover for a capacitor?
I am just reading 35V and 100 something, maybe 100uF?
Could actually be as you mentioned a capacitor before

Had customers putting black plastic and stuff on my machines already and i looked for some time before realising its not from my machine

I think I found the origin of this capacitor:

This is the transfer alienation motor. As you can see, there is an identical capacitor. This motor sits right over the fuser front. Clearly the capacitor is still there, so it must have come from a previous unit.

And yes, the very worn belt was causing the C4505 codes (skew values exceeding 92+). =^..^=

Now all you have to do is identify the positive and be happy
