Mailing machine including methods and systems to reduce weighing errors when operating in a differential weighing mode

摘要

A mailing machine is provided, that when operating in a differential weighing mode, can detect if a user has replaced one or more mail pieces that may have been inadvertently removed at the same time back onto the scale. If the mailing machine detects such replacement within a predetermined time period after the scale has stabilized, the weight calculated for the mail piece can be reduced by the amount added back to the scale, or alternatively the user could be requested to confirm that multiple pieces were inadvertently removed from the scale at the same time and the user is trying to correct that error and a new weight determined.
