Likes: Yanni is right. Developer is not "consumed", it just "carries" the toner. The consumable life % doesn't mean the developer was removed from dev unit it just means that's how much it's carried the toner in it.

you are seeing the % of life left on the DV units themselves.
We know a thing or two because we've seen a thing or two.

Exactly how will you determine the toner density, and or the proper quantity of developer? =^..^=Originally Posted by yianni
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

I am using C8000 developers in low speed machines, cheap but ORIGINAL option, & works very much fine.
In my experience, as I have a lot of these machines in the field, running drums past life is fine but if they go too far they will begin to deplete developer prematurely. We used to set the machines up in the shop with all consumable reminders off until we started to notice c-255x codes relating to undertonned/overtonned developer units, to which the only cure is replacing an $800 developer unit (sometimes multiple). Because the genuine Konica Minolta drum units run for so long before showing lines/streaking, the risk of the drums zapping developer units increase. We have since turned the drum reminder on at the expense of maintenance customers calling for us to replace the drum units.
This thread was an interesting read...even if it was from 2018.
Yea and i am the guilty one reusing the developer....
Whatever
Can't help it i have to spill.
Developer does get #u&ed in more than one way. The sharp corners for the grains gets warn down and your nice and puffy mag brush is not the same anymore and these rounded grains have a way of breaking free from the magnetic field. Toner gets impacted onto the grains also making it less attracted to the magnetic field, it gets heavier and the extra weight is not magnetic. With the impacted toner machines using toner to carrier ratio sensors will count the toner stuck to the developer as part of the toner concentration and will read a higher TCR value leading to less toner supplied and resulting in light prints. Eventually a lot of the developer would have escaped from the tank and some machines have a minimum value of toner it will add counted by hopper rotations. If there is still enough developer in the tank to cover the mag roller the set amount of toner added will be too much overshooting the TCR target leading to over-toning. Then there is paper dust, its got a way of getting into the dev tank and then just accumulates in there. The paper dust is added to the toner side of the ratio and leads to the machine not adding enough toner.
You can setup a bench tool to read TCR value of a dev toner mix if you really want to.
Its amazing to see that most of the developer used by the OEM's are the same stuff regardless if its color or not.
Whatever

I'm very glad we have here many actually thinking engineers not only toner jockeys/masters of screwdriver. Sometimes I feel so lone where I am 😅
