1,000,000 prints. =^..^=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.

Thanks! Just to make sure you mean the actual unit right? Not the powder?Comment

Yes, the powder. The upper developing seal will begin to curl at 6M. The developing unit is rated for 8M, and often gets 10M. =^..^=If you'd like a serious answer to your request:

I agree in parts. We always recommend customers to follow the manufacturer.
However, one of our contracts has already reached 12M without changing the Developing Unit

Ok that makes sense, thanks. My specific machine is at 8.6M. The current dev unit doesn't seem broken but I'm not sure what to look for exactly. What is generally the thing in the unit to break first? I'm starting to think the issue is more of an electrical one.Comment

You'll start to see jitter-bars crossfeed, as the developing bearings go bad. Also take care not to turn the developing roller in the wrong direction. If you manage to flip the sheet below the mag roller, it is extraordinarily difficult to get it flipped back. =^..^=If you'd like a serious answer to your request:

Yes I did that but thankfully someone stopped me before it flipped I think. Broadening my issue with the 1250p right now I'm getting some developer leakage into the machine. Could it be some overvoltage? The 2412 error code came on when it started. (I did a dev reset in service menu so that's gone) Or could those dev seals you mentioned be the issue?Comment

C-2412 is the toner sensor, so I'd say you're justified in ordering up the developing unit and developer (especially at 8.6M). =^..^=If you'd like a serious answer to your request:

As far as life of the developer powder it really depends on what media/ coverage the customer is running. We have a print shop that runs a lot of color pre-printed heaver stock media. They have very little coverage so sometimes we are only getting 60-80% of life. When you start having toner build up on the small roller in front of the mag roller you know its time to replace the developer. If you have a 2250 ( two 125's hooked together) and the customers runs a lot of one sided prints then engine ones developer will start misting because its just being agitated with no toner leaving. This is because engine two prints first side and engine one prints second sideComment
