Abstract
Disclosed is herein an initializing method for printing type rings in a printer having printing type rings, a sensor disc and a detector portion which constitutes a plurality of main detecting portions and an end detecting portion, the printing type rings being stopped in predetemined positions with pulses provided from the sensor upon opposition of the main detecting portions of the sensor disc to the sensor, followed by printing, characterized in that plural pulses provided from the sensor upon rotation of the sensor disc are counted to determine a minimum pulse interval and the pulse counted just after the omission of pulse counting for a period larger than the minimum pulse interval and smaller than the interval between the main detecting portion located at the terminal end and the end detecting portion is judged to be a pulse provided by the end detecting portion opposedly to the sensor, whereupon the printing type rings and the sensor disc are stopped.
