The present method provides assurance in positioning a print head at the initial print position in a serial printer using only microcode programs. When any trouble, such as a mechanical failure, a drive logic failure or a feed back signal control logic failure, occurs in a head carrier calibration, the machine is stopped to indicate the error code of the defective area to be isolated.
