A machine that is operable to create a series of holes in at least one sheet of paper includes a base, a punch mechanism positioned on the base, and a tray coupled to the base. The tray includes a first guide and a second guide. The tray is configured to move between a first position and a second position. Movement of the tray between the first position and the second position adjusts a position of the first guide and a position of the second guide relative to the punch mechanism. |
