Just bought C650 w/ only 500 clicks on it. We had a dedicated circuit for our old C500 (20 amp breaker) & my friend bent the prongs on the new C650 power cord to fit the outlet, not realizing the C650's power supply & cord is rated for 15 amp. Unit started to power up, but threw a code, we heard a "click" & it blew the small 5 amp fuse near the power supply. We installed a new fuse & it keeps blowing them. Does anyone know if it could be a simple fix or how we should proceed from here? Is there a circuit board we should check or?? The guy we bought it from , made a simple pigtail to plug into the outlet in his garage, & it ran fine, so I assume it was a basic 15 amp breaker that's in most homes. Thanks for any help.

Most circuits in modern buisness locations are wired as 20A circuits, even if the outlet is a 15A receptacle. In a home that's different. A 15A circuit is usually just a 15A circuit and cannot support a 20A draw, even as a dedicated line. The 20A rating is peak draw, and occasionally yes, your copier will draw peak amperage.
Bending the prongs was just a bad idea. If the receptacle you connected to was wired incorrectly your could have cooked a power supply or more.
Start with the electrican. Get yourself a true dedicated 20A circuit. Then have a tech take it from here. No simple fixes off the forum here.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 for the input. The receptacle is fine & our C500's been plugged into it & running fine. We've got he power supply out & a tech friend is looking into his manual schematics for info. Is there a specific board or circuit/fuse, etc we shoud check?Comment

Sorry to be the bearer of bad news.
Your C500 is a 220 Volt machine.
You just fried your C550, which is a 120V input 20 AMP input, by forcing it to take 220V.
There is no telling what kind of damage may have happened to your machine, but I can guarantee you, it is serious. I can also guarantee you there will be no warranty because your friend was a STUPID IDIOT and bent the prongs on it to accommodate the different outlet.
The only thing I can recommend is call your nearest Konica Minotla service department and have a QUALIFIED technician look at it. There are no circuit diagrams available to the general public. I do not even have access to these. In all likelyhood, your power supply is toast, and quite possibly you may have taken with it a few other boards, including the PRCB/MFPB."Many years ago I chased a woman for almost two years, only to discover that her tastes were exactly like mine: we both were crazy about girls."

This. I had a customer plug a Di650 into a mis-wired 220V outlet a few years ago, and it destroyed pretty much every board in the machine. With this customer, it luckily turned out to be the electrician's fault so they were able to push the bill off to them. In your case, since you plugged it in without checking to see what you were doing, even if you had a contract, you'd be getting a massive bill. Sorry.Comment

Dang! Thats a nasty! 220V into a 120v PS.. yeah if thats the case more than likely the power supply would have been taken out, and quite likely then some.. I don't have a c500 manual handy to verify the line voltage but that may be the case (20amp 120v has the perpendicular pin/plug on the opposite side to 220v, but they look very similar). Wish you luck and hope you didn't toast the machine.. only 500 clicks...
Regards!

Thanks for the info, even though its bad news. Guess we'll start w/ the power supply & have an electrician can diagnose & fix it. Maybe we got lucky & it didn't damage anything else..Comment

A tech recommends calling Nationwide Board Repair & sending the power supply to them. Maybe I should send them the other board you mentioned as well. Is there anyone you can recommend that we send the PS to?Comment

Just called HyTech board repair in FLorida & they work on Konica minolta. Their tech said its probably just the power supply & has rebuilt ones in stock, so one is being overnighted to us. Hopefully, it'll work & I sure appreciate this site & all your input, too. Will keep you posted.Comment

There are control signals that go from the power supply to other boards, like the printer control board, multifunction control board, C-board that possibly have been damaged as well. Unlike power line spikes that can sometimes transient through the PSU the odd time, this is something that quite likely damaged many other components throughout your machine. It all has to do with the voltage tolerance of those components. Doubling the voltage through the machine may have severely done damage to the voltage regulator circuits from the PSU, and that voltage, whatever it might have been, can wreak havoc elsewhere.
What I am saying is, do not be surprised if one of those other boards is indeed damaged and causes a feedback failure to your NEW PSU, taking that out yet again, or does further damage elsewhere. As I said, it is best to have a KM tech involved, they can remove the appropriate components and reinstall them for you, you can still have the third party do the repairs, or go through KM technical repair center. Not doing so may cost you a lot more in the long run."Many years ago I chased a woman for almost two years, only to discover that her tastes were exactly like mine: we both were crazy about girls."

Installed the new power supply, ran a dedicated circuit w/ correct amperage, etc & it fired right up. Got code C3B04 & reset the machine & it appears to be up & running. Was sweatin bullets, so a $200 fix ain't too bad. Bet my friend will never do that again!Comment

Wow....good show....
yer friend owes you a couple cases of beer I think.

A beer awaits as soon as we get one more problem resolved. The fuser temp is fine, but we got a codeC3B02/3/4 code & cleared the code. Got full display, but the start button flashes orange & we can't copy anything. Called Hytec & tech says to reflash the firmware. Does that take a Konica rep to do that? We called a local repair company, but haven't heard back. Its a $160 service call to flash it, so that isn't bad, but they also said it could be a bad printer control board, but Hytec can't test a C650 board. Is there anyway we can reflash it ourselves? Any recoommendations are appreciated. Thanks for the help & Wish we could buy you a beer, too.Comment

The Power supply to the fuser unit ( IH power supply ) and/or the fuser unit coil are shagged...
The gene pool could use a little chlorine.
