My Xerox 6180 MFP hangs up in the calibrate mode about 3 times per day. I turn it off and back on, then it works for a while more. I have been reluctant to reset back to the default settings because I'm not sure it will fix the problem and it will be a lot of work to get everything set back up properly. Any advice on how to correct this or troubleshoot in a logical way?

Thanks, Hube
