I have a C250 with a recurring C-D371 error. It clears with the S71....* sequence, but comes back after the machine is idle for about a half hour. It will not recur if the machine is printing. Another member here suggested the problem may be a bad NvRam battery. Can the battery be replaced and will the NvRam work afterward? The battery only costs about $14. It sounds like a much cheaper way to go than to replace the board.

Re: C250 Bizhub NvRam
There is a NVRAM recovery for this model and if the Nvram is bad itself, that board can be replaced thru Konica Minolta. Call a tech. -

Re: C250 Bizhub NvRam
Thank you all. Unfortunately, calling a tech is not an option I have: I haven't been able to find a tech for this machine in my area, Toledo, Ohio. I did not want to tell this story because I didn't want to offend anyone, but now it seems unavoidable: When I first got the machine I called the local service company and they sent someone out who, by his own admission, had never worked on one before and did not fix the machine. The company was not too proud to charge me $192.10 for the service call, however. Since then, I've had to fix everything myself with the help of the service manuals and the Theory of Operation Manual, and of course, forums such as this one. The original problem turned out to be plugged inlets to the waste toner box, by the way. I have no aversion to hiring a tech who knows the machine. If any of you can recommend a tech in this area who you know personally or by reputation that has "chops" on this machine, I would appreciate it. It's a fairly complicated beast, and I'm doing the best I can to keep it running. I think it's worth the effort. It's an amazing machine when it's running well, but it's about as complex as a space shuttle.
P.S. I made a mistake in the original post. The error is C-D36E. It does not occur if the machine is running a job, but will occur in about 10 minutes if it's just sitting. It clears with the S071...* sequence and will run just fine after it starts back up.
Thanks again for your help.Comment

Re: C250 Bizhub NvRam
If the code comes back after reset then it will prob need a new NVRAM. (from KONICA MINOLTA)Comment

Re: C250 Bizhub NvRam
Thanks. I bought a used board with an NVRam on ebay, that supposedly was working when it was removed. I'll install it and see what happens. What I do now is just spool up the jobs, turn the machine on and let them run, and then turn it off. This system is ok, but keeping it on and warm seems like a good idea.Comment

Re: C250 Bizhub NvRam
You may discover that it won't work, even if it worked on the other machine. The NVRAM is serialized with the machines serial number. If the number conflicts with the number stored elsewhere it will code out. that's why it has to come from Konica Minolta. It must be programmed with the machines original serial number. Just so ya know ... =^..^=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.
