I have a Smith Corona electronic typewriter. I got it a year ago and the keys worked, except the characters wouldn't show up. I replaced the ribbon, but now the keys won't work at all. What's wrong?

If your Smith Corona XD 5500 typewriter is only producing specific characters and some buttons are not working, there are a few potential issues you can investigate:

1. Check for Stuck Keys: Make sure none of the keys are physically stuck or jammed. Press each key to see if they respond properly and if any are consistently stuck in the down position.
2. Clean the Typewriter Mechanism: Over time, typewriters can accumulate dust, debris, or dried ink, which may impede the movement of keys. Use compressed air to blow out any dust and try to clean the typewriter mechanism.
3. Inspect the Ribbon and Correction Tape: Check the typewriter ribbon and correction tape. If the ribbon is improperly installed or the correction tape is stuck, it can affect the functioning of the keys. Ensure that the ribbon and correction tape are correctly threaded.
4. Check for Mechanical Issues: Inspect the internal components for any visible signs of damage or misalignment. Ensure that all the moving parts are functioning smoothly. If you notice any broken or misaligned parts, you may need to seek professional repair.
5. Verify the Keyboard Switch: Some typewriters have a switch to toggle between different character sets or functions. Check the user manual for your specific model to see if there's a switch that might be affecting the keyboard.
6. Test the Typewriter in Manual Mode: Most typewriters have a manual mode where you can type without the ribbon or correction tape engaged. Test the typewriter in manual mode to see if the issue persists. This can help determine if the problem is related to the typing mechanism or the printing elements.
7. Consult the User Manual: Refer to the user manual for your Smith Corona XD 5500 for troubleshooting tips and information about the specific features of your typewriter.
8. Professional Repair: If the issue persists and you're unable to identify or resolve the problem, it may be necessary to seek professional repair. Contact a typewriter repair specialist or a local office equipment repair service for assistance.

Remember that working with vintage typewriters may require specialized knowledge, and attempting to disassemble the typewriter without proper expertise can lead to further damage. If in doubt, it's advisable to seek professional assistance for repairs.

If you have the old spools your best bet is to wrap a new ribbon onto the spools.

Is the ribbon selector lever located on the right side of the keyboard switched to either red or black? If it's on white, the ribbon doesn't come up.

Did you buy an OEM or COMPATIBLE ribbon? If you bought a compatible, please make sure you have bought the correct design for your typewriter. Some compatible ribbons come with a lug that prevents them from sitting correctly.

I note that you posted this problem over a month ago. If you haven't solved the problem by now, i would advise you to contact www.inkribbonpaper.co.uk. I have used them a number of times with great success for our smith corona, brother and royal typewriters

Your keyboard assembly needs to be replaced.
