[CQ] 8 series drum life

[EarthKmTech]

Can they be extended, yes or no?

I already know the answer from my own experience, having to keep them in the car and change them for customers for "lines on print" on a regular basis.

However being told "its not happening anywhere else" is the usual reply.

So, "is it happening anywhere else?"

They seem to be making the manufacturers quoted yield ... just barely. Not twice to three times the stated yield like the e series. The major difference is the change from charge wires to charge rollers. It must be the physical contact that makes the difference. =^..^=

This is also my experience.

Hopefully some more people can add their experiences too.

Just gets past yield.

Least the yield is correct. We are so use to drums exceeding life we almost expect it now so when it only manages maybe 110% we fill ripped off.

Re: 8 series drum life

pretty much advertise yield . once in awhile you get lucky and it goes longer

Re: 8 series drum life

We average about 1000 over advertised yield. Better than not making it to yield I guess.
Changing from a charge corona to a charge roller is the direct cause of this, and the only reason KonMin made the change as far as I can see. They give some phony ozone reduction reason, but getting $200 every 100k instead of every 200k is the real reason.

Mmm does a DR512 fit in there?

Primary charge voltage will be significantly lower for a charge roller than a corona wire. I would expect black copies (assuming you could make it fit). =^..^=

Re: 8 series drum life

Yeah all this changing to charge rollers for ozone tree hugging green stuff has just made drum life awful. Also you can't really pop these rollers out like on a Kyocera and clean all that built up paper dust that accumulates on them due to cheap paper.

Re: 8 series drum life

I had one that showed the lines at 2 % life left.

TO extend the life, frequent cleaning of charge roller is the only option, which depends upon quality of paper and environmental conditions.

Re: 8 series drum life

Havent been that lucky to get them to run over life,had many fail long before they were due.

Re: 8 series drum life

you can modify a k drum to fit for a colour which takes the cost down

and yes its the charge rollers
