Konica minolta C552 Error Code C-DC10 and DC30

format the HDD, it seems a security issue. did it have a card reader or passwords just to use it?

[Znaiber]

No it was working fine and when i changed the developer unit it showed DC10 code

something is not right.
was it an OEM or compatible?
code has nothing to do with DV unit unless DV spilled on a board and shorted an ICP or something.
not a good sign for a dinosaur machine.
its a security code. any c-dc code.

this does not happen from replacing a DV unit to the best of my knowledge.
on that series though ive had a shorted out DV unit once that came up as a fuser code because they shared the same ICP but this is no fuser code.
if all you did was replace the unit, reset the trouble code and try the old unit.
if error comes right back id start looking for a new machine.

I would start but unplugging the HDD & updating the firmware.

You may have just been unlucky powering down the machine to replace the DV unit cased the error, especially if it has not been powered off for a while.
