Check IMG-CONT in service mode,under copier-option-img-cont. It should be set at 1. But this will only matter if there was a imagepass connected. So if you see a printer tab in the control panel LCD then there was a imagepass connected and there might be a possibility that the value is set to 3. When this occurs sometimes the control panel will lock up.
