Vintage IBM electric typewriter w/ font ball

Vintage IBM typewriter with a font ball in place. We've plugged this in, and it started, and then blinked on and off, most likely the terminal for the cord needs cleaning, or there's a short in the power cord? The cord looks fine.

I'm embarrassed to say that I don't really know how to use a typewriter, and I had a hard time figuring out any of even the simplest of the functions on this one!

This came out of an estate with a couple of other typewriters, all carefully kept, so we'd expect that it'll work? It's in very nice clean condition without wear, staining etc. to the housing, it doesn't look as though it's been used a lot or very hard. All the same, we're selling it as a machine in need of a tune up, because we can't assure you this works right now.

Please email us if you have further questions or need photos of angles or pieces we haven't shown. Thanks!
