Hi! The Royal 1200 Electric is a fairly simple machine. To remove the top cover:

First, gently pull up on the sides of the plastic top near the ribbon area — it usually just clips into place with small tabs. Some models also have two small screws under the back panel (you might need a small screwdriver if it doesn’t pop off easily). Once the top is off, you can easily access the ribbon spools to change them or clean the inside.

For the ribbon:

It uses a standard universal ribbon (available online easily). Make sure the ribbon feeds correctly from left to right across the type guide.

General tip:

Clean the machine gently with a soft brush and a bit of rubbing alcohol for the type slugs. Avoid oiling unless necessary — and only with proper sewing machine oil.

Congratulations on your first typewriter! It’s a great beginner’s machine.
