Swintec manufactures a variety of office and business machines, including electric typewriters with presets for adjusting margins and tabs on the typed paper. Clearing the preset margins on a Swintec typewriter takes only a few seconds.

Toggle the power button on the left edge of the Swintec typewriter to the "On" position.

Press the "Return" key on the right side of the keyboard to send the carriage to the far left starting position.

Press the "Clear" key to erase the margin setting stored in the Swintec's memory.

Press the "Tab" key repeatedly on the upper left corner of the keyboard to advance the carriage to the right margin, where it will stop.

Press the "Clear" key once more to erase the right-margin setting stored in the typewriter's memory.
