I would start with checking paper type. If paper in the drawer is plain and customer set it on Thick3, after a few continuous pages this could be result (plain paper is overheated)
Also a flat silicone roller inside fuser can cause this. Check this on site.

I have done all that with the the paper type, and set a new fuser. but continue happening not always like I had say, last time I was there was 9 days ago since I changed the fuser so everything was ok for that time till yesterday call again same problem but is only one time then I happen no more.

Are there no error codes in service mode? Jam 32-02 or so?
Does the paper stuck in the fuser or after in the duplex switching guide?

If the paper doesnt go trough the fuser maybe you have damp paper.
Print 20 pages and search for water drops.

Occus, the paper goes normal, it passes the fuser and after the exit unit comes the accordion paper as per the client, as I said I havent see the machine doing this but he is the one that tells me and shows me the paper, when I am there I tested printing 100 pages one side and 50 double sides and I get no problems, I check service mode for jams of problems and there is not a single problem or code. that is why this drive me crazy, I am keeping cheking the manual and also I was thinking maybe is a clutch or motor from the exit unit, because as he said the paper goes thrughout the fuser and comes out of the exit unit as accordion.

Re: Konica Minolta 250i accordion paper after fuser

Your problem is above the fuser unit, right after the fuser unit. Some exit roller is holding the paper causing this problem. It's worth disassembling and cleaning, looking to see if you can find anything that shows the problem.

I was thinking the same but what holds me to disassembling is that this is not a always thing, it happens here and there after amount of days, last time that it happened was 10 days, so for now I have bring new paper to the client, may be the paper he is using doesnt seem like a good paper, the box has no brand only says 90 grms, but seems ticker to me. so I will test with this paper is that happens again I will opt for switching the exit unit.

I would bring with me a ream or two of paper and just crush the hell out of the machine testing it.
Not the first time we are chasing ghosts of good working machine 😂

Is this happening in the horizontal paper transport area?

Strip and inspect the switchback unit. Could be a tooth missing from a belt or gear.

Re: Konica Minolta 250i accordion paper after fuser

If it has a finisher remove it and the relay unit for a few days to see if that's causing the problem

Interesting, typically at what mileage they are seizing?
