High Durability BK Drum DR315K

[copier tech]

Apologies if this has been asked before but what are your experiences with the High Durability BK Drum DR315K, worth the extra cost vs life?

I thought the only difference was the chip count, so the the OPC drum etc were identical.

There is a better cleaner on the charge roller, other than that mostly the same drum. I tend to use them on the 45 cpm and above only as I’ve not noticed much increase in life on the slower models.

I’ve not had the chance to compare the 2 side by side. How have the ‘improved’ the charge roller cleaner?

we were told to wait for a required f/w update to use these..your post made me realize that I never saw anything later to allow usage..The cost is about the same if you compare stated yields..not sure if I want to spend almost 2x per drum only to have them crap out as well.

This backs up my thought in that the only difference is the chip count/life.

The first picture is the long life drum, the second one is the standard drum. You can see the charge roller cleaner is different. I believe they changed it to help prevent drum score marks.

Any firmware from g00 v1 onwards will enable use of this drum.

Thanks for the pics. Not sure how this would stop the OPC wearing out.

This backs up my thought in that the only difference is the chip count/life.

No counter data is stored on the chip. Chip consists of a drum set resistor and a fuse that reset the count on the machine.So surely you must change something on the machine to in crease the yield info. So guess it will be firmware and soft switches. Once its done you need to replace only with the high yield drums.

That improved pcr cleaning setup is already on the dr314 for the 8e bk models, in comparison with the regular dr313k those long life drums just fail at half life in my experience.

It might make some difference but i'm skeptical as to it being worth twice the price.
