ABSTRACT:
A postage meter module includes die protector blades to prevent fraudulent taking of postage meter imprints. A first plurality of die protectors are retracted to expose the adjacent printwheels when the meter makes a check on its internal condition. The remainder of the die protectors are retracted under different conditions while the first are still retracted in order to enable an imprint to be taken. Preferably the remainder of the die protectors are retracted only for a predetermined interval after a print signal has been received. The die protectors also serve to align the printwheels when the protectors are retracted.
