Abstract: An assembly is provided for adjustably aligning sheets of material, particularly sheets of print material fed into a printing apparatus. The assembly includes an alignment section adapted to convey the print material in a direction toward the printing apparatus. The alignment section includes first and second guide members for controlling the position of print material passing through the assembly. Each guide member extends generally parallel to the direction toward the printing apparatus. The assembly also includes a control mechanism for adjustably securing the position of the guide members. The control mechanism includes a first and second shaft extending laterally to the first direction. The first guide member is supported by the first shaft and the second guide member is supported by the second shaft. In this way, rotation of the first shaft selectively translates the first guide member longitudinally along the first shaft without translating the second guide member.
