Abstract

A paper tray or fixed platform for loading paper includes an adjustable edge guide including a primary paper guide surface and a cantilever portion including an end surface, the end surface movable between retracted and extended positions, so that when the end surface is disposed in its extended position and the edge guide is moved to bring the end surface in contact with a supply of paper, the primary paper guide surface is sufficiently spaced away from the supply of paper to avoid paper pinching and excessive clearance conditions. The edge guide is molded as one piece with a living hinge, removed from the mold while warm, and a pin is inserted to prevent the cantilever portion from warping toward the guide surface during cooling.
