Failure Color Registration Bizhub C368

[tulintron]

Color registration failure.

After a power surge, the C368 stabilizes but then presents color registration failures. Consumables lifespan is ok. I just couldn't get the printer to work properly. It always goes out of registration after a few prints.

Can someone please direct me?

Try print head skew adjustment.

Have you tried cleaning the IDC sensors?

Wow! That is a first. I've had other things happen from surges mostly blown MFP boards, pwr supplies,etc but never where it wouldn't hold a setting. Just to be clear the machine was working fine until power surge? Does machine have a "real" surge protector like attached pic? If not I would get one. If all else fails initalize the machine and then check or change settings. FYI most settings are factory set at "0". The service manual will show you the factory defaults which is a good place to start. And last thing would be a bad board.

A power might have adversely affected one or more of the sensors or the memory where the readings are saved.

copyman do you have the tool to read the surge log? i have both, one for ESP and the other for innovolt i think that reads it wth an IR device to your phone. the esp to your laptop via usb.
whenever there were weird jams and codes for no reason id check the log in the surge protector and show the surges and outages and power droops. when they coincide with the jams it was easy to insist on a new properly grounded dedicated outlet with less than .5v neutral to ground. in most cases it did solve the problems.
had a school with a new rooftop AC unit installed over the summer and when it kicks on the copiers would get false fuser temp codes.
I also like the fact if the machine fries through the SP the surge company will pay for the damage when they get the faulty surge back and see it didnt do its job.

Hey, sorry for the hijack OP, I get excited when i see a product being suggested im a true believer in.
I humbly return you to your thread already in progress

I don't have that tool but sounds great. And good tip about the less than .5v neutral to ground. This is very important and most techs never check.

I know about the surge protector companies & their warranty but never heard of them paying a claim. I remember when working for a large dealer they put a few claims in and was never paid. The surge protector company blamed everything else like an insurance would do not to pay!

Thanks to everyone who helped and I will try to answer in order

TSB, Print Head Skew was performed.

BR549, IDC sensors were cleaned

Copyman, we have surge protectors, but the customer chose to install a no-break in July/24. He didn't install it and now he's having problems.

Slimslob, that's what I thought, but I replaced the MFPB, ITB, WriteUnit, Drums, but without success.

I'll get back to you next week with news.

Thank you.

Sorry, a "no-break" is a diesel-clutch-generator or motor-flywheel-generator or ...? - to supplement surge protectors?

A "No-Break" is a term applied to a power protection system that may or may not include a generator. To be truly "no-break" it must provide continuous AC output, unlike low end battery backups that do not start generating power from their batteries only after at least half a cycle of AC line failure. The no-break UPS has its output being generated constantly while the line input is only used to charge the batteries. They include not only surge protection but also sag and brownout protection.
