Abstract
A method of detecting mailpiece thickness includes detecting a leading edge of the mailpiece, moving a detecting roller downwardly over a first predetermined period of time from a first position to a second position where it contacts the mailpiece, increasing a compressive force applied by the detecting roller to the mailpiece from an initial force to a predetermined measurement force over a second predetermined period of time, and applying the measurement force to the mailpiece for a third predetermined period of time. The method further includes applying the measurement force to the mailpiece for a fourth predetermined period of time and making a number of thickness measurements of the mailpiece based on a position of the detecting roller, and determining the thickness of the mailpiece based on the number of thickness measurements.
