Having quality issues. I replaced all drums and developer units, tranfer unit and secondary roller, high voltage pwb, feed image pwb, drum dev relay bd and still the same after speaking with kyocera support. Background and banding in different colors. Swapped drums around and the background changes color. Stumped on this one. See attached help appreciated.
that drum seems to be bad, especially since the background followed with the unit. how did it all start?
Presuming it’s genuine toner I’d try HVT
Check to see that the drum cleaning units are not blocked up with waste toner. I suspect that the waste auger system is backed up, backing up into the drum cleaning units and primary transfer cleaning unit. =^..^=
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.

When you replaced the units drum, dv, transfer are all the counts for those unit zeroed

You said you replaced the drums, but was it with new drums because those look pitted.
Look for above, along with toner dropping (front from dv bushing wear, rear from clogging).
It's due for a PM by date and the firmware is about 4 revs old.
175k on color supplies. That's early for a complete PM.

By Date….PM kit warranty is by time or volume because both cause degradation. I get that nobody really takes it into account except the engineers who designed it.
After 4-5 years in the field, hasn’t the customer essentially paid for it already?
Time spent screwing around certainly paid for it.
This would a fascinating topic. I suspect that most owners/managers don't want a tech replacing a drum/dv/ITB/fuser unless it's shows signs of wear. You raise a valid point. Personally, I haven't worked on these machines long enough to collect any real long term data.
I rely on you guys for a lot of this information.

I believe what they want is for you to do what you were trained to do. Exercise your best judgement because they aren't technicians, that's why they hired you
Most Dealers price a PM into their Service Agreement CPC (if they are savvy) and certainly expect you to perform the PM as prescribed because the manufacturer expects it of them.
Back in my day () we had to do a PM twice a year no matter what and we cleaned the whole machine. We replaced parts so that they DO NOT FAIL in the future, we did not WAIT FOR THEM TO FAIL. (Preventive Maintenance vs Periodic Maintenance)
Would you wait to change your oil until your compression drops and your rings show signs of wear? Would you run or work for a shop that did that to others? Especially if the customer had already paid for it?
I think you know better
Of course I was trained in the USMC so I'm a 'By-the-Book' guy.
