    Bizhub C4050i problem

    Hi,


    I'm new here and I'm having a pretty big problem with the Bizhub C4050i. The error is that I have installed a new firmware. The printer accepted it, but since then I have not been able to enter Service Mode or Administrator settings - I get an error about too many password attempts and I haven't tried many passwords. Printer displays error D073. Most functions are turned off. I don't have NVRAM reset tools or anything else. Please help.

          Unfortunately, nothing happens after going through this procedure. Still the same. The administrator is locked.

              unplug it for 5-30 minutes, that is the simple unlock.

                  Unfortunately, nothing happens, even when the device has been disconnected from the power supply all night. I still can't reset my password or get into Service Mode. Is there any other procedure?

                      Sounds like you need to use the reset tool file.

                          At what version was firmware before? And now it is?
                          After doing firmware update did you get the chance to enter service mode or it was locked straight after that. You need to deal with D073 error before which if I'm not mistaken is storage type error. I would try also to downgrade FW back to previous working version if it's possible.
                          A tree is known by its fruit, a man by his deeds. A good deed is never lost, he who sows courtesy, reaps friendship, and he who plants kindness gathers love.
                          Blessed are they who can laugh at themselves, for they shall never cease to be amused.

                              Have you tried to enter service mode from the trouble reset screen?
