ABSTRACT:
An improved lid for a forms feed tractor, which feeds successive interconnected sheets of paper having edge perforations (feedholes), the sheets having forms printed thereon or being blank, in printers, copiers and the like is provided with an improved lid mechanism having an extension outboard of the tractor and over the form. A transparent or translucent window section in this extension is provided with markings which are seen when the lid is pivoted down and closed so as to capture the form. Then the form can be moved so that the edge of each sheet or certain markings on the form are in proper alignment in the printer or copier. Then when printing occurs or when copying onto the form occurs, the printing will be located in line with other material on the form or properly spaced from the top edge of each sheet.
