Abstract
A die protection mechanism that prevents the taking of fraudulent, non-metered impressions from the value printing die surface of a postage meter machine. A linkage assembly is pivotally supported adjacent the print wheels of the postage meter machine such that a projecting portion will extend beyond the diameter of the print wheels when the postage meter machine is inoperative, but the linkage assembly will be pivoted during operation for the purpose of allowing the printing of postage on a mail piece. The mechanism is particularly useful in a postage meter having a reciprocating platen.
