Loss of funds prevention for postage meters and personal computer meters

摘要

In a postage meter, funds are requested from an accounting unit and transferred to a print buffer when a print registration sensor detects a mailpiece at a location that is sufficiently downstream of the printing mechanism in order to enable the meter sufficient time to compose the indicia. A presentation sensor detects the presence of the mailpiece just prior to printing the indicia; and a printing mechanism prints the indicia if the mailpiece is properly aligned with the printing mechanism, or stores the indicia data in a secure register if the mailpiece is not properly aligned with the printing mechanism to enable the operator to obtain a refund.
