With the 4650 I am getting a 49.5001 error at the end of inilization. I have tried a cold start and other suggestions but no luck. I have read that a firmware upgrade could solve this problem.
I finaly got the lj4650fw_07006.0.rfu downloaded and getting ready to update. I reading on "how to" suggetions, I noted a few comments on others conserned about the update ending up with "brick" - the printer has been "distroyed". In the event somethimg goes wrong, can I just replace the Compact Flash drive (which I believe holds the firmware) with one containing the current firmware and have a functioning printer?
