A method for processing output voltage from an optical basis weight detection sensor for a weight detection system. The method includes the steps of calculating an average voltage of all the output signals from the sensor for a given measured paper, calculating a standard deviation of these signals, and comparing the average to a predetermined range for light, average and heavy paper. If the average voltage is at a boundary between ranges for light, average and heavy paper, the standard deviation is used, and if the standard deviation is small, the heavier paper will be registered.
