    Bizhub C-458, panel unresponsive..

    Hey guys... So, I've had several machines do this and rebooting is the only way to get the control panel to function again. The panel comes up just fine and the machine works normally as a printer, etc. but icons cannot be pressed. I've tried replacing the HDD with no luck. I also removed and reinstalled the SSD Board, no luck there either. Has someone fixed this problem and if so, what did you do? The firmware is up to date, the machine has been reinitialized and hard drive PHYSICALLY formatted, several times.

    Thank you in advance!

              may sound silly but have you tried re-seating the video cable to the panel and mfp board a few times in case it has a bad contact?
              or calibrating it if you can get it to work long enough?
              We know a thing or two because we've seen a thing or two.
              The medication helps though...

                  Also free, you could try uninstalling Marketplace. That uses a lot of resources, slowing the panel reactions. =^..^=
                  If you'd like a serious answer to your request:
                  1) demonstrate that you've read the manual
                  2) demonstrate that you made some attempt to fix it.
                  3) if you're going to ask about jams include the jam code.
                  4) if you're going to ask about an error code include the error code.
                  5) You are the person onsite. Only you can make observations.

                          Hi, I have had this problem.
                          The solution was to replace the complete control panel. In service mode there is often an C-4091, FA-14 or E301
