Resetting the margins on a manual typewriter.

I can't be for sure if these are auto set margins, but it sounds like they might be. If they are, first move the carriage as far to the right as you can. Hold the Left Margin Set (not Margin Release) lever as you move the carriage all the way to the left. Release the Margin Set Button or Lever. Now hold the Right Margin Set Button or Lever (not the Margin Release), and move the carriage all the way to the right while holding the Margin Set. Once the carriage is all the way to the right, release the Margin Set. Move the carriage to the place you want to set your left margin. Hit the Left Margin Set and then release. Move the carriage to where you want to set the right margin. Hit the Right Margin Set and release it. It gets confusing, but Margin Release does not set margins. Its sole purpose is only to bypass the margins. Hope this helps.
