Transfer Roller damaged, damaging Drum Unit

Re: Transfer Roller damaged, damaging Drum Unit

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.

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.
