ABSTRACT:
In a label printer printing on individual labels carried in spaced relationship on a surface of a longitudinally moving backing strip, this invention discloses apparatus for adjustably sensing leading edge positions of the labels. A stationary member is carried above the backing strip on one side of the backing strip. A movable member is carried by the stationary member for longitudinal movement along the path of the backing strip. There is provision for adjusting the longitudinal position of the moving member. A sensor is carried by the movable member for sensing leading edge positions of individual labels as a function of a change of thickness between the backing strip alone and the backing strip with a label on the surface. Both optical and mechanical versions are disclosed.
