Phaser 6180MFP error 117-313

[rpcvdvet]

My second-hand but trusty Phaser 6180 has displays error 117-313 on startup, which I understand is a Controller Communication Error.  No panel button has an effect in this "frozen" state.  Net searches gave multiple causes for the fault.  One suggestion was to reset the machine to factory defaults.  I'd like to try that, but cannot figure how to access the System menu, as no single panel button works.  Is there a secret combination of buttons that, if pushed, will allow me to access the System menu?

Thanks in advance.

Hi rpcvdvet,

Thank you for using the Support Forum. Please take a look at the solution for resetting the machine.  If your panel is frozen and you have powered off, unplugged the machine waited 60 seconds and then plugged it back in and turned it back on and the panel is still frozen then you will not be able to do the reset and would need to contact your local support centre to request service.  Please consider contacting your support centre for further assistance.
