Electronic postage meter having microcomputer-controlled motor-printwheel alignment

Machine a affranchir electronique a commande du moteur de roue a caracteres par micro-processeur


A postage meter comprises a non-volatile memory and a microcomputer in communication with the non-volatile memory. The microcomputer is operatively coupled to a stepper motor. The stepper motor includes a rotor and is arranged for positioning at least one printwheel of the postage meter. The non-volatile memory has stored therein a value corresponding to a predetermined pulse width required for pulsing a coil of the stepper motor to position the rotor to a final position between step positions. The microcomputer pulses the stepper motor coil with a pulse of the predetermined pulse width for bringing the stepper motor rotor to a final position for positioning the printwheel.
