acp3525dn "52.00 error" displayed

[rdyjnkns]

CP3525dn displays the "52.00 error" 5 seconds after "Calibrating" during boot up. The original problem with the printer is that it would stall at "6/6 A/F". That was resolved with a new formatter. Then "59.F0 error" which was resplved with a new fuser drive assembly. The "52.00 error" is not in the service manual. Any assistance would be deeply appreciated.
