Abstract (en)
[origin: US4618275A] Method for resetting the print head of a typewriter or similar machine to a starting position. In a processor-controlled typewriter or similar machine, the steps of a vertical repositioning of the recording medium are added and stored. If the added value indicates an upward movement of the recording medium, this value is cancelled as a character is printed. If, contrarily, a downward movement of the recording medium is indicated, the value is retained. Moreover, the current horizontal position of the printing head and, when it is repositioned horizontally, also the position of the last printed character, are stored. Upon initiation of an automatic reset function of the printing head to the end of the printed text, after a repositioning in horizontal and/or vertical direction, for instance for purposes of a correction, the stored information is evaluated for activation of the printing head drive and the recording medium drive.
