Dear all,
I have replaced the PRCB board on an old bizhub C550, but now when I start the machine it is first showing error code C-5351 which is related to the power supplu fan trouble, I opened the front door and the problem disappear. Afterward, the machine says section doors are opend please close section properly (bypass, vertical transport, and 4th cassette). Someone can tel me what to do please, I am pretty sute yhay all doors are correctly closed. hank you in advance for your support

Go back and inspect all the connector and sockets for bad pins or insertion on that board.

Is the power supply fan working?
