ABSTRACT:
A print media alignment apparatus is disclosed. An embodiment includes a first member configured to apply a varying force to at least one print media sheet of a print media stack. This force varies from a minimum below a first print media stack height to a maximum at a second print media stack height. The alignment apparatus also includes a second member configured to apply a constant force to the print media stack irrespective of the stack height. Another embodiment includes a print media width adjuster configured to be moveable adjacent a print media stack having at least one sheet of print media, the print media stack defining a plane. The alignment apparatus also includes a wall on the width adjuster. The wall includes a wall first print media contact surface configured to slope at an angle with respect to the plane. The alignment apparatus further includes a member attached to the width adjuster, the member including a member print media contact surface configured to be perpendicular to the plane. A method of aligning print media for use in a printing device is also disclosed. The method includes the steps of applying a varying first force to at least one sheet of print media at and above a first print media stack height and applying a second constant force to the print media irrespective of the print media stack height. The varying first force and the constant second force facilitate uniform alignment of the print media.
