LETTERS TYPED ARE NOT THE ONES PRINTED - Olympia Mastertype 3 Typewriter

Usually there are stops that have rubber bumpers on them that rot off but can still be adjuste. They are at the ends of the segment.

Push down on both ends of the platen and see if it snaps back in place.

try other keyboard if the problem don't appear that's hardware problem, may be the rubber under the key responding each other, it is easy to open the keyboard casing then you can check the problem inside

Check slide knob lower left of keyboard is set to 10, 12 or 15 and NOT ps.

somewhere in your property settings there is a checkbox called "mirror". It sounds like this is in the checked position. Uncheck the box and try again. GOOD LUCK!!

If the characters at issue are the UIOPLKJM then press Fn + Numlock to turn it off
If other letters are effected Like " and - then go to Regional and Language settings in control panel and ensure you have the correct keyboard/language selected on all 3 tabs

If the characters are showing up different than the ones you pushed then your wheel is probably bent. First, open the clear cover on your ml100. Second there is a black lever that you pull towards you. Next, you pull the wheel out and if any of the arms on it are bent than straighten them out, and make sure none of the arms are over lapping. Next, return the wheel, push the black lever back into place, close the clear cover and then hold down the code button and press the reset key (the "q" key). If that does not work then you need a new wheel. This is what just worked for me, I hope it helps.
