There were a couple of different kinds of machines. The mimeograph used “stencils” – you typed on them and the typewriter basically punched the letters through the stencil. The stencil was wrapped around a drum and ink came through and onto the paper as the drum turned around.
The machine with the nice smell was – I think – called a spirit duplicator. It was sorta like using carbon paper. You typed on a white sheet and the letters pressed onto a backing sheet. You couldn’t make as many copies with a spirit duplicator as you could with a mimeograph.
Both of them were messy and inefficient and it was tricky to correct your typos. You used this blue gluey fluid with the mimeo. You had to take the stencil out of the typewriter, brush the fluid over your mistake, wait for it to dry, put it back in the typewriter and line it up right.
With the spirit, you used a razor blade thingie to scrape off the mistake.
I remember typing wills using carbon paper. If you made a typo, you had to start all over again, because you couldn’t have an erasure or cross-out in a will. Gah!
You kids and your Delete keys don’t know how good you have it!

One small nitpik (let’s face it: our posts are the only info these whelps will ever see on the fine art of mimeography): the typewriter (usually) did not punch through the stencil, just shoved aside the waxy coating on the mesh backing material.
If you caught your typo when you made it and weren’t at the bottom of the stencil you could scroll down a few lines, do the correction fluid thing, then scroll back up and retype it without the registration problems. I always laugh my creaky arse off when some conspiracy-theorist type looks at an old mimeographed document and finds something sinister in what are obviously mere typo corrections.
Was the spirit duplicator the thing that produced copies in that hard-to-read purplish-blue ink? I remember they had a “funny” smell, but didn’t think it particularly pleasant. Gad, I hated taking exams printed that way.
I’d forgotten about carbon paper. Perhaps we should add familiarity with that (and with manual typewriters) to the list of FOGI prerequisites.
