The figure illustrates a combined cover and access door, where the door may be pushed against the platen to pinch and hold the paper just below a perforation for removal of a printed sheet from a continuous web. The figure is a cross-sectional view taken perpendicular to the paper path in a printer. The printing mechanism 1, such as a dot matrix print head located on one side of a sheet of paper 2, prints by reciprocating laterally across the surface of the paper. The paper is supported on the opposite side by a platen 3, which provides a smooth impacting surface. The paper may be single sheets or a continuous web having perforations 4 extending across the width of the paper to facilitate separation of individual sheets.
