Konica Minolta C250 - Konica Minolta C250 code C-FB52 - what's up?

Welcome
The Konica Minolta C250 copier displays the error code: C-FB52

Turns on, heats up. You can print the demo test, it comes out very nicely.
There is a problem when trying to copy.
After pressing START, this code C FB52 crashes.

Can you give me what is going on?

According to the service motherboard (CFB52 DMA_A error interruption), nothing more I can not say, turn on the device with the button / counter pressed and press the button on the panel "troubleshoot reset button" which appears immediately after the minolta logo and restart the copier too probably nothing gives ...

Hello
I know that the website is written:
CFB52 DMA_A error interruption • MFP Control Board C
But something I do not want to believe to do so by itself "down" ...
Tomorrow I will check the wires, no more power today

Maybe to the complete set, reinstall its firmware.

Welcome
The machine finally entered our warehouse.
In free time I leaned over her for a moment.
Unfortunately, one thing I noticed is:
After entering the service, in the section: HDD / MEMORY BUS / SCANNER MEMORY -> TEST / start, after pressing "losses" immediately pops up "CFB53", not "CFB52" - interesting ...?
The test (MEMORY PRT) passes - OK

I still do not know where it's allocated scanner memory ... < br />
Do you have any ideas?

Regards

P.S.
I shed a CD50 from C250 somewhere ...
Can you give me info on how to do NOV-RAM?
Do you have a different firmware to c250? I would try it to upload others
Do you have files for her?
