Failing cyan developer set up. Tried multiple developer units. Swapped EPU pcb with the last one. No help.

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.

Re: estudio 6570c
Will try to get bias readings tomorrow. Page count around 12k total. Is there any other information we can get that helps you out?
tnrtt is my tech. I was there watching a lot of this. The reason we changed developer units is because we were getting light spots in the cyan. After we did that, it seemed to just be sucking blue toner and developer like it was going out of style. Upon setup it kept giving cyan developer abnormal and would throw a C390 upon reboot.Comment

Re: estudio 6570c
Ah! Now that's more like it! Error codes! Observations! Nouns and verbs. Much better.
It would probably be better to remove the hopper, then run cyan developer stir, then color calibrations.
Before you do any of that though, replace the cyan drum and EPU-KIT-FC65G. The primary charge may be shorting causing the developer to dump.
You may discover that the developing unit is not agitating. Maybe drive, maybe motor...

Re: estudio 6570c
Sorry Blackcat. Since this thread was directed at you, I should have realized you'd want more information than that.
The whole story from the beginning. Customer was getting feathering in their color. I could tell by looking at samples it was cyan. Pulled cyan unit, emptied out remaining developer and installed a new cartridge, ran 05-2403, no problem. set up at 115. Customer had finished the color job on the other 6570c they have. After I was done, the customer started a long run with little coverage. I decided to babysit for awhile. When it was done I ran a ltr test chart in the UI and could see the cyan was fried again. it wasn't spilling developer in the machine. I had the same idea as you. I replaced the drum and EPU kit on a different drum/corona module the next morning. Inspected the developer unit, swapped toner sensor with known good one, . Ensured mag pole was adjusted per bulletin and checked mag blade gap. Checked springs and plates, always check the auger drive every time. Pulled EPU tray and visually inspected developer drive and hand rotated couplings, installed cyan developer cartridge. didn't throw error code, just said developer was abnormal, check unit. Tried running routine again, got same message. value was 5.01 first time, 4.60 second time. Had a used charged cyan developer unit with me. Put that in and tried to run setup, same message. Fired up to see what would happen. Got the C390 at that point. That's why I didn't mention it since it was irrelevant. I went to shop and got a unit and EPU pcb from a running machine. Got same setup message. Fired up no problem, quality control and color registration, auto gamma all fine. That's where I'm at. Will be going back 1st thing tomorrow to see if I can figure out WTF is going on. Thinking I must have damaged something in the EPU tray pulling the developer unit in and out. At an impasse.Comment

Re: estudio 6570c
How is the main charge anything extra on it / good tension on the grid. Check the contacts at the rear of the EPU I've also had a broken connector on the machine side for the cleaner assy, with folded over connectors

Looks like we MIGHT be good to go, all! Dev seems to be holding up now. Thanks for your help!Comment
