The right margin on the Olympia SG3 is a known thing:<br /> - https://typewriter.boardhost.com/viewtopic.php?pid=27528#p27528<br /> - https://typewriter.boardhost.com/viewtopic.php?id=3521

They say roughly what my experience is with both of my Olympia SG3 right margins: - If you're typing characters, the line lock will engage and require you to hit the margin release to continue. - If you're tabbing, spacing, or using the carriage release you'll blow right through the margin and can keep typing.

The number of spaces from bell to margin will differ based on the pitch of the machine as will the number of spaces one would need to space past the margin before the line lock disengages and allows you to type in the margin again.

It was a change in design of how a right margin stop worked in late typewriter manufacture.

Correcting Bad Typing Habits with the Smith Corona Electric Typewriter 63024 by [[PeriscopeFilm]]

Motion should happen only at the level of the fingers and not at the wrist or even the arms. Type only with your fingers and not your wrists or arms.

Allow the carriage to glide to complete the carriage return rather than wasting addition time and energy on pushing it all the way. Let the momentum do the work.

Use the paper release when removing letters to reduce wear on your rollers and prevent ripping of the paper.

Drop the paper into the top of the platen and against the paper guide to improve alignment can save time.

Setting the right hand margin will help save huge amounts of time from the transcriptionist looking back and forth to get proper margins otherwise.

Using correct typing for numerals will speed up typing numbers as well.

For the top tabulator, use your index fingers alternately instead of hitting it with your entire hand.

Hugging the keys with your fingers allows you to type faster, much like a drummer keeps the sticks closer to the drumhead when drumming quickly.
