Color drums/IUs yield problem

Re: Color drums/IUs yield problem

Like tsbservice said, here in EUwe do not have such a service unfortunatelly. In my country in case of warranty claim we need to provide not only counters, but also Management List. We usually get claim solved in form of additional discount with future orders, not in replacement parts.

BTW...only now I see what those "M" in drum usage means - MINUTES! So I recon there's no direct translation from minutes of use into pages printed, probably becasue waking from sleep rotates all guts inside, which translates into minutes of use, but not into pages.

Interesting info was also provided by Max:


Found further explanation on this:

If i may ask where did you find the information that the M stands for Minutes. I assumed that the M value would be Minuets, but one of my work work colleague argues that its not Minutes but Meters. I would like to find documentation stating the units behind the M value.

I can not see that its possible to convert that M value to a per page count. All depends on the amount of time the machine stabilizes or use primary charge roller retraction base on the setting that determines black, productivity or color quality priority.

Re: Color drums/IUs yield problem

We don't have YPP unfortunately here in Europe afaik.
That being said we were denied with bizhub C250i with 30k counter and rattling sound from fuser due to 'machine is 1 and a half year old therefore out of standard 12 months warranty'. You know 30k is under 5% of quoted 800k life but it's what it is.
I think it depends on price of the machines what is included but I may be wrong.

Wow, I can see how that would make things extremely difficult on you guys, and why some of you go through such lengths (like aftermarket parts and rebuilding) to keep things going at all costs.

tsbservice: The fact that all you get is a standard 12 month warranty is pretty ridiculous in my opinion. In the US, consumable parts in the Business class machines (non-desktop style) are guaranteed that they will make at least 80% of their listed life expectancy (at a prorated rate of course), for both the original and replacement parts. While I'm not 100% sure if this is supposed to be possible, as I've heard differing stories, I've claimed 5+ year old original fusers that didn't make life and not had a problem.

Labsy: It is basically the same here. In order to file for any sort of warranty, I need provide Model, Serial Number, Part Number, Install Date (of part, or of machine is part is original), Page Count at install and at failure, what the issue is with the part, along with a copy of the Managment List. They ship out a replacement part within a few days if one is available and bill you for the part. Once the part is shipped, you have to return the bad one (at your cost) to them. Once they receive the bad one they will evaluate it (possibly test it?) and if it checks out, will then issue you a credit to your account for the prorated amount.

'M' refers to rotation time of each unit so I believe it is indeed minutes.

In the "Quick reference parts guide" it states "Life: copies or minutes" it has all of the drums units, transfer units/rollers as "minutes" not copies

Well, that would be fair, if yield would be listed that way. But in catalogues it is listed in pages count and that's what customer can count and expect. In reality no customer can count minutes of drum units running, as it depends on many factors - every wake up consumes minutes without printing, and printing pages one by one consumes a lot more minutes than printing in batches of 20 or 30 pages. Indeed there's small print on consumables life expectancy, saying it is counted in contious printing batches of 30 or something pages. But at the end, if fusing dies at 20% life after 18 months, neither we ac reseller nor customer are eligible for replacement or partial replacement (in form of extra discount for premature dead of consumable). So if/when this happens in most cases we try to deal extra % from KM, and we sell with full discount to end customer, all in the manner to keep customer happy.

Re: Color drums/IUs yield problem

KM has used minutes of use for the consumables for a pretty long time.
viewing consumable life by page count is more of a production machine thing.
