ABSTRACT:
An articulating paper sensor for sensing the presence of continuous paper in a tractor drive assembly for transporting continuous paper along a travel path. The articulating paper sensor comprises a body having a portion including a sensing element for detecting continuous paper and producing a signal in response to such detection. The body is pivotably attached to the tractor drive assembly. When the tractor drive assembly is positioned to have continuous paper loaded therein, the body is moved to a remote location relative to the continuous paper travel path; and when the tractor drive assembly is positioned to transport continuous paper along the travel path, the body is moved to a location relative to the travel path such that the sensing element detects the presence of continuous paper in the travel path.
