Human Factors
During preflight we received a planned DG printout (6 pieces/198.42lbs). I secured the printout to the glare shield above my Electronic Attitude Direction Indicator as a reminder. With two jumpseaters and a pushback operator difficult to hear/understand; I was distracted. Once we turned the dome light off I really didn't notice my reminder on the glare shield. We pushed back without the DG final; which usually prints up automatically with final weights. Apparently the ramp agent was unable to send his final report. We realized our mistake after engine 1 startup. We cleared a very congested ramp area at [ramp spot X] and had the final DG report sent to ACARS from dispatch while parked safely on the taxiway.
During preflight; we received a planned Dangerous Goods summary. The Captain reminded me that we needed a final dangerous goods summary before we departed. The final dangerous goods summary did not automatically print like it usually does; and the Captain and I both forgot about it before we pushed back. We contacted Operations to resolve the issue; and we were advised that the ramp was having a technical issue. We exited the ramp area since it was congested and we were unable to sit there and wait for the final DG summary. While on the taxiway; dispatch sent our final DG goods summary.
Air Carrier flight crew reported gate departure without required Final Dangerous Goods Summary.
