I have one of the later Robotron-made typewriters, an Olympia Regina de Luxe, that was produced around 1984.

Some webpages say, that the Robotron-Typewriters (like the Erika 100) were good machines until the production ended in the year 1991.

And although it makes a good overall impression and the mechanics are clean, I have a problem with the key press resistance. For example compared to the Nakajima-Typewriters from the same time period, on the Robotron-Olympia it is far more exhausting to type a full page.

Does anyone have some hints how I could to improve it?
