ABSTRACT:
A type band for a printer comprises a track of marks to be scanned (timing marks) at least one of which is obliquely positioned relative to its adjoining marks. The centers of all marks are equidistantly spaced. When the horizontally moving type band is vertically displaced, the time spacing of the scanning signal of the obliquely positioned timing mark is changed over the scanning signal of its adjacent timing mark. The magnitude of the vertical displacement of the type band is derived from the change in this time spacing. The displacement data thus obtained permit compensating for the vertical displacement of the type band (using, for instance, a stepper motor).
