The present disclosure relates to methods of using a machine for manufacturing continuous toilet seat cover reels. Methods include: loading a continuous paper roll onto a shaft in a first end of the machine; threading continuous paper on continuous paper roll through a continuous paper reel transmission mechanism, a printing wheel, a modular cutting mechanism, a counting wheel of the machine, onto a reel at a continuous toilet seat cover reel output device in a second end; perforating continuous paper roll to form sheet perforated tear lines, a splash prevention perforated tear line, one or more vertical splash prevention perforated tear lines and horizontal splash prevention perforated tear lines; counting the number of toilet seat cover sheets generated on the continuous toilet seat cover; and cutting the last sheet of toilet seat cover sheet from the continuous toilet seat cover to produce the continuous toilet seat cover reel.
