Narrative:
We utilized the ACARS weight and balance procedure during pre-flight. We noted the ZFW to be 83.7 on the takeoff data provided by the ACARS and then verified it. During taxi-out we noted a scratch pad message; 'check ZFW.' I went to the weight initialization page and noted the ZFW was now 85.6. We informed ATC that we would need a few minutes prior to departure and held short of the departure runway.I went back to the ACARS and printed up the takeoff data and we inserted/confirmed the correct ZFW manually; confirmed the ZFW cg; tow; and tow cg; then re-inserted/confirmed the correct v-speeds and power settings. The flight continued without further incident.
