This is a bad internal memory of the MFP board.
Frequent repairs.

Do you just re-flow the solder on the RAM chips or do you replace them?

Have had some kind of issues on C451-C452 series machines, some one above mentioned the internal RAM and I recon the same. But replacing the MFPB seems logical and you can try on the replacing the RAMS later....

I replaced the MFPB today. I won't know for a while if this fixed my issue or not. As of now, things are printing fine.

Repaired by replacing the ram chip.

So the customer called back today and reported the same issue. I'll stop by tomorrow to confirm, but any other things you guys can think of that I can check on while I'm there? MFP board has already been replaced.

Thanks in advance.

Any update about problem...

The last thing I did was move the copier to another location in the same room. I had a similar thing happen to me on a different machine at a different location where the same problem presented itself even after replacing the machine. I'm basically trying to eliminate the install site from being the issue, whether it be power or network related. Waiting to hear back from the customer and will report back.

I'm currently troubleshooting a strange issue on a Muratec MFX-C5590 (Konica Minolta C558). Please see the attached sample. Copies are fine, print jobs from the User Box are fine, meter counts are fine, management lists are fine, gradation prints are fine, but network print jobs have lines, demo page has lines and configuration page has lines. I've never seen this before. I can restart the machine and things go back to normal, but the issue comes back. Hotline seems to think it's the MFP board, but I wanted to see if anywhere here has been down this road before.

Wow, I do not know the data-flow, but this has to be an I/O issue:
Network, demo and config only glitching is odd--are you [or should ask can you--no idea] on this model print the demo/config through web interface? Using a network command seems to be the only possible common denominator... ¿
This just gave me a headache... also RAM (as noted), Firmware, or bad cabling? Also unset/set any options this machine has?

Just thought I'd link this post to mine with my solution. It ended up being the dual scan board. When this was replaced the issue was resolved. (It was a suggestion from Konica Minolta)
