Open the CIPO recordAbstract From the Canadian patent
A postage meter includes a printwheel setting mechanism which allows shortest path setting of the printwheel. Stepper motors are provided for each printwheel which drives the printwheels through a transfer gear having a large diameter and greater number of teeth so that there are multiple positions of the transfer wheel which correspond to a particular character to be printed by the printwheel. The stepper motors are microprocessor controlled and a routine calculates the shortest rotational path of the setting of a new character for printing.
