Kyocera 7002i thick solid black line

Interesting enough, both started this after PM Kit was done.

Thanks for the advice. Will try an old transfer belt and keep cleaning

Yeah if you still have the old ones put them back in and it should stop it.

I am still battling with this problem on a 9002i on and off for 2.5mil on the counter. every time I replace the maintenance kit, it solves it for a while, then it just returns. I must also add that I also do not feel comfortable with the "new" type transfer belt. Also, the old belts never had problems staying in the center.

I can’t believe this thread has been running so long and I’ve missed it. This issue has driven me nuts on our hi volume client with the 8002i. It would do it maybe 2-3 times every 10k . It looked to me to be some sort of static discharge issue. Over six months I’ve changed out just about every board and drum, dev, transfer component. It started happening at around 10 million prints.
I never fixed it.
Client bought a replacement Kyo 7003i when it got to 14million prints.

Yeah sounds like our issue. It only does it every once in a while and it's impossible to trace down. We've replaced everything like you as well and it still does it sometimes. The only thing that made it almost stop doing it was an older style transfer belt.

You have probably been told this already but I cant see it posted, With the new transfer belts there is an issue with them tracking off centre. in the transfer belt kit you should get some pieces of mylar to stick on the frame and you have to run copies and then check that it is running 10mm each side (if i remember correctly). if it runs to the edge it grounds out causing the line. good luck.

But I had different effect on print before adjusted the skew.

Printed black was not solid...

Are you guys still seeing this black band issue ?
I am not finding the transfer belt is pitting a ring around the drum, I think the transfer belt is arcing to the drum, causing drum damage.
You have to look real close at the drum and there is pit marks on the drum.

This machine has been doing this off and on and will stop doing it for months and then start doing it again. It is very sporadic and usually only does it once or twice a day or usually only a couple of times a week. Kind of looks like high voltage shorting out for a second and we put a new kit in it not too long ago, it did it before and after the kit. I have attached an example of it and paper is traveling in direction of the arrow I put on the sheet, we told the customer it is hard to diagnose if it only does it a few times a week.

We only have one machine doing it and ot only does it once or twice every month or so.

I have that exact issue.. belt looked centered to me but I have that pitting on the near edge of print.

Did a new belt fix it? Gonna replace drum/belt then make sure it's centered it looked centered to me.
