If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

As I said before, I don't know that machine, but just working by the priciples of copier/printer basic mechanics. The transfer roller springs IMO, should never be cut or modified, as you also mentioned. It has the right enough tension, even it looses a bit in age, it should not be a problem.
A question though. When you guys say you replace the drum, is it the entire assy or just the drum itself. The assy , as far as I see from the parts manual, has the charge grid and wire, the cleaning blade and the recovery blade. I see, most replace the cleaning blade and not the recovery blade. The recovery blade also gets worn and leaks toner, which gets onto the drum and then it drops on the charge grid. There is also the felt, that the drums sits on the ends that gets worn and needs to be replaced.
Panasonic drums use to have these kind of issues as the entire drum parts had to be replaced or you would get all kind of symptoms, of toner leakage and lead to all kind of problems, if they were not rebuilt properly.
Me, I stil think the problem is in that drum unit. The spaces do not rotate. The transfer roller rotates and the inside of the spacer has to be worn for the spacer to be a problem. This is my theory anyway.
Let us know your results as you mention.

I tend to agree with you. I've had transfer roller springs go missing ... and I've had to choose a replacement from my miscellany of springs ... but I've never tried to alter the transfer roller pressure.
These drum units only come from KM as an assembly, but there are aftermarket sources for drums & blades. And yes, in my experience the biggest problems with drum units are the result of a poorly performed rebuild. Specifically there is a positioning adjustment for the drum within the assembly, and if it's not correct the developing roller spacing will be wrong, the charge wire spacing will be wrong, so one side or the other side of the image can be light if that rebuild is done incorrectly. IMHO the savings from replacing individual components in a drum unit are not worth the poor final results. =^..^=

I have seen this but drum damage was outside image anyway and drum unit was over life and changed. Transfer roller also regularly changed, will check pressure next time.

Thanks for your reply. As for the drum I never change the parts. I always change the entire essy. The srange thing is that if the scratch strats even at 80k that will be ok for me (the drum life is 100k). But when it starts at 1k this s not normal. Sure I will update and hope the issue will be solved.
