Insert the correction paper into the typewriter. This usually requires using the roller on the side of the typewriter to insert the sheet on top of the original document.
Set the typewriter to "stencil" mode. This will turn off the ink, facilitating the use of the correction paper instead when required.
Use the keys of the typewriter to align the paper for correcting the letter that was typed incorrectly. Use the space bar to move forward on the page and the delete key to move backwards.
Strike the letter while still in "stencil" mode. This will apply correction material over it, making the error unnoticeable.
Align the paper again to the same position as in step 3.
Set the ribbon of the typewriter to "print" in order to use ink again and type the letter correctly.
