Hi there - I have an old Smith Corona XL1500 typewriter that I've just started using. It was working really well using the old ink cartridge that was in from when it was last used by my grandparents in the 1980s.

But after I replaced the ink cartridge with one from Amazon, it stopped working as well. It worked for a while but then went completely kaput - I think because the cartridge and typewriter machinery aren't aligned properly? Whenever I try and type, it isn't typing words, just big marks from the wheel.

Does anyone know what might be wrong and how to fix it? I live in London and am struggling to find a business that can repair it. Any ideas gratefully welcomed! Thanks
