Vintage Sears Roebuck Word Processing Typewriter 10K40 W/ Owners Manual and Ink

Typewriter gets power and all keys and levers seem to work. I couldn''t get it to type anything but I''m not really sure how to use it. So I don''t know if it needs repaired or if it was user error. It is in good condition looks wise. It comes with 2 ink cartridges that are from 1995. I do not know if they are good anymore.
