first image is ok , second not good , third is worst and so on. Noticed at the background the interval is equal to the perimeter of charge roller. I replaced charge with no result.
Any idea? In the attched files the 2nd and 3rd copies

Did you check the dev units? Is it Original Kyo toner ?

Your machine is dumping black toner, and collecting it in the paper dust collector. The registration roller smears it around on the page. You'll need to vacuum out the paper dust collector, the suction system in the back, and clean the registration rollers, Then figure out why it's dumping. Is it generic toner? Is your developing unit over life?

toner is katun. The problem with genuin toner is that it is too expensive. You can buy it from internet for about 155 Euros . If i buy it from wholesale i buy it for 153 Euros . So there is no margin
Also we have distance in prices from competition

Your Katun toner caused the problem. You will need to totally clean out the developer unit and use original Kyocera toner. You might have to replace the developer unit if it was damaged by the toner. SOO no savings there by using Katun toner.

Cheaper is always better but in the long run it costs you more!

Nuff Said.

Yes, the registration roller paper dust collector is a brush that wipes off the registration roller.

And Yes, the Katun toner is the problem, and will continue to be the problem until of it is all gone. Just changing the toner cartridge is not enough. You must vacuum out the toner hopper also. It's possible to consume the Katun toner out of the developer, but it's a slow process, the toner will continue to dump throughout the machine until the genuine toner populates the system, and your customer will continue to be unhappy until all that happens.

I use katun toner with lot of these machines and i have problems with only two (the same problem).
i noticed first copy is perfect and the rest going to to worst . i noticed that the magnetic cylinder accumulates toner on one side and that accumulations exceeds making more copies. And again the next set of copies has its first copy perfect next is not so good and its going to worst. Can it be something else?

[blackcat4866]

No, it can't be something else, but feel free to ignore the good advice you have already been offered.

You may have been lucky to get some Katun toner that was goof but their consistency varies greatly because they do not produce their own toner.. So who ever supplies them is not a proper manufacturer. Pot Luck on quality.. Good luck with dour dreaming.

Katun toner, been a dealer for 42 years and non OEM toner is NEVER a good idea. It will always fail at some point
