Re: Kyo M6535cidn Black drum marks

Done maybe 50 in the last year... Dk-5140(A) does make a difference but I've seen those get the dreaded dash as well.

I polish them with t-cut but you've got to catch it early otherwise the dash wears out the cleaning blade and within 2 weeks it will return. I've had decent success keeping known good cleaning blades and using those after polishing the drum.

I think it's two things causing it.. heat and the other is very low coverage so theres not enough toner cycling through the cleaning station. They should add as part of the calibration full coverage of the drum every so often just to get fresh toner into the drum unit.

What makes this really annoying if you take the belt out underneath the belt, toner collects behind a black piece of mylar when you tilt it that drops toner on the belt so you get black dashes from that to..

IMO reducing the wax in the toner would resolve the issue, but I'm not an engineer.

It's sad that this is 6 years old and people still get dash marks. It happens on just about every A4 model we have sold from Kyocera. I asked a tech one time, and he said they probably went with a cheaper option and the good was going to outweigh the cost of the bad. With the amount of drum and DV units that we warrantied, they had to have lost money. I've read a bunch of forums on here, and the only one that potentially COULD fix the issue, is the one that points out the sleep timeout, because the internal temp of the machine stays too hot for too long and in the end it's the cause of the dash marks. It made sense to me, but who knows. Haven't tested it in the field long enough to see if it works yet. Time will tell.

Updated drums and dv units have made no difference at all to this long overdue problem. We're a small dealership and run into it constantly to the point of now telling our customers to expect a few little marks here and there because that's just how the machine runs. When it gets too bad, then they call and let us know. Will try the lowered sleep timer setting but am skeptical on that as well.
