Gauge needles not working properly

[Tbdavis]

Recently painted all the gauge needles in my '84 c10. Slipped paper behind them one at a time to protect the gauge face which seemed to work fine. In the process a few of the needles were bouncing around while positioning the paper and now aren't working properly. They work but the needles aren't positioned where they were originally. Not sure if they merely need to be re calibrated and if so not real sure how to go about that. Again, the gauges are working but the needles aren't positioned as before. Any suggestions as to how to go about correcting the problem would be appreciated.
