The stepper motor drive positions value rods carried by the main shaft according to the value of the postage to be printed. The printhead assembly includes a value module mounted to an outer end of the main shaft so to rotate with the shaft. A dater/slogan module is also mounted to the outer end of the main shaft assembly and is positioned or indexed, such as using guide pins, to the value module. The components are housed within an enclosure including a separate printhead cover assembly. The printhead cover assembly includes an opening through which the field service personnel has access to the dater/slogan module to allow the them to remove the dater/slogan module, such as for maintenance or repair, without affecting the security of the meter.
