"Working but needs new ribbon" is almost always seller's code for I have no idea if it really works, but I'm going to try to sell you this machine for the price of a fully functioning machine that was just serviced by a professional shop despite the fact that I just took it out of grandpa's barn and I'm not sure if the mouse inside is dead or not. Also, I can't afford $10 to replace an old ribbon to truly participate in the charade of the price I'm going to try to fleece you with.
Educate yourself a bit: <br /> - https://boffosocko.com/2025/03/29/first-time-typewriter-purchases-with-specific-recommendations-for-writers/ - buying typewriter ribbon: https://site.xavier.edu/polt/typewriters/tw-faq.html#q1 and https://boffosocko.com/research/typewriter-collection/#Typewriter%20Ribbon - typewriter 101: https://www.youtube.com/playlist?list=PLJtHauPh529XYHI5QNj5w9PUdi89pOXsS
If you want to tell people Tom Hanks taught you to change a typewriter ribbon: https://www.youtube.com/watch?v=GBbsNKaVAB0. There are lots of other YouTube videos out there for specific machines as well as reviews of them.
You can definitely test out a machine without ribbon, but if they're trying to charge you over $100 for a machine, it really should have fresh ribbon.
