Hi TTW
Your typewriter appears to be working correctly. The wheel to which you refer is the ribbon spool platform and is part of the ribbon advance system. In your short video, the system is effectively moving the ribbon from right to left. Only the take-up spool turns when keys are pressed, the other spool is allowed to rotate freely to feed ribbon off to the take-up spool.
If you look just above the spool platforms, you will see what looks like a small fork. The ribbon passes through both of these forks as it travels from one side to the other. The ribbon for these machines should be fitted with an eyelet about 6" from each end. When the eyelet reaches the fork, the fork is pushed sideways changing the direction of ribbon travel. Move the right fork towards the left until it clicks over (about ½") and try typing again. You should find that the right spool platform turns clockwise and the left spool spins freely. Hope this points you in the right direction,

We humans go through many computers in our lives, but in their lives, typewriters go through many of us.
In that way, they’re like violins, like ancestral swords. So I use mine with honor and treat them with respect.
I try to leave them in better condition than I met them. I am not their first user, nor will I be their last.
