We were faced C2650 in Bizhub-223 around three months before, but it was clear simply by Trouble reset, after that machine worked perfectly but now have this code again and not to be going off in either way.
Has anyone seen this issue before?

Dealing with 1 now. It is the EEprom on the PRCB board on ours. trying to get a part # to replace it. You are not supposed to use a used part.:cool:

Ye s. Ssd boards are special order through km dealers only.

Try just reseating it. Take out the screw, pull it off, blow off the contacts and when you reinstall and tighten the screw, pus the ssd board above the connector so it does not skew.

Nope not the NVRAM. This is on Printer Control Board. Little 6 pin eeprom that you change over if you have to replace that board.:cool:

what model are you on? the 223 has no eeprom on the prcb that i can see in the parts manual or remember ever seeing.

Could help to just reinstall it. Could be creeping out of the socket.
Believe it contains data like the TCR value and life counter values.
Don't need to change it out but could help to avoid C2557 C2558 problems.

But i could be completely wrong.

Actually it has 1 IC51 EEPROM mounted on PRCB. When PRCB is replaced old 8 pin EEPROM have to be remounted onto new PRCB.
