Hi Comma
As others have said, the Skyriter takes a standard ½" ribbon which is reasonably available. However, only Smith Corona series 3 spools fit the Skyriter, so if your unit came with spools, you're good to go. The trick to removing the old ribbon from the spool is simple, but a little care must be taken. The ribbon is held onto the core of the spool with a 'C' shaped clip which is easily removed by simply pulling the ribbon off the spool, just be sure to wrap your hand around the spool or the clip may go flying across the room.
To install the new ribbon onto the spool, lay the ribbon over the core of the spool with about 1" of ribbon to spare. Set the 'C' shaped clip over the ribbon and press it into place around the core. A little practice makes perfect. All the best,
Sky
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.
