That ghosting effect you're seeing may be down to your typing technique. Computer keyboard typing technique is different than typewriter technique. If you're pressing hard and/or bottoming the keys out, you may not be getting your fingers out of the way and causing the key to double strike while you're lifting your finger up.

Instead, type as if they keys are hot lava. Strike and release them as quickly as possible and that ghosting should clear up. For more on technique, try: https://hypothes.is/users/chrisaldrich?q=tag%3A%22typing+technique%22

If that isn't the issue, is that ghosting happening on all the keys or just a few? Cleaning things out certainly couldn't hurt: https://boffosocko.com/2024/08/09/on-colloquial-advice-for-degreasing-cleaning-and-oiling-manual-typewriters/

Joe Van Cleave hypothesizes that the slightly blurry and/or ghosting letters on typewriters may be the result of the typebar just hitting the typing guide and moving slightly as they do thereby creating issues with the type clarity.
