Narrative:

APU started normal after landing in ric. Upon entering the ramp in ric, APU generator off bus caution illuminated on EICAS. After parking at gate, engine was shut down to prevent aircraft from being on battery power if the APU generator would not reset. Following aom procedures, the aircraft went completely black as it appeared that the #1 dc bus went off line. Numerous warnings and cautions illuminated on EICAS. APU generator was immediately deselected and the #2 engine was shut down. Smoke was seen blowing past first officer's side window. No smoke or fire warning from EICAS. Flight attendant advised that he could smell smoke in cabin. I exited the cockpit and visually confirmed that heavy black smoke was exiting the APU intake duct. APU fuel shutoff and APU fire extinguisher was pressed. Flight attendant was advised to expedite deplaning remaining passenger. Advised ramp to call for crash fire rescue equipment equipment. Smoke dissipated shortly after the fire extinguisher was activated. Unable to de-power the aircraft using normal checklist. After consulting with maintenance an electrical reset was performed. Aircraft successfully de-pwred. No injury or harm to passenger or crew.
